Hi there,
I am writing my own app for reading data from TI GasSensorEvm module. However, I am unable to.
This module exposes unknown service and unknown characterstics.
Could someone please tell me details on how is data (gas sensor values) sent to mobile phone using TI GasSensorEvm module?
Thanks alot!

Hi all,
I am developing on TM4C129X Development board with TI-RTOS 1.20.00.28 and TI-NDK 2.23.00.00, CCSv5.5.0.00077.
I am finding if TI-NDK 2.23.00.00 supports both IPv4 and IPv6 simultaneously in one network application.
There are 4 ethernet examples: Tcp/Udp Echo IPv6/IPv4.
In Tcp Echo IPv4 example, I tried to set Global.IPv6 = true in tcpEcho.cfg file and it still worked well. But when trying to set Global.IPv6 = true in udpEcho.cfg, it seems that the udpEcho application cannot get IP address from DHCP server any more. Then I tried to set static IP address for the board ( Add Ip.address = "192.168.1.148"; Ip.mask = "255.255.255.0"; Ip.gatewayIpAddr = "192.168.1.1"; Ip.domainName = "abc.net"; to file udpEcho.cfg)
but this did not help, I couldn't ping to the board from my PC.
In file tirtos_1_20_00_28\products\ndk_2_23_00_00\packages\ti\ndk\config\package.xs, I see that libs are linked depends on Global.IPv6 value.
Do you know if I can enable both IPv4 and IPv6 in my network application?
Thanks in advance,
Viet Hoang.
For the BQ24295 charger, when the /CE pin is high (disable charging), the input does not supply any current to the Vbat pin, correct? With this, is the input pin still connected to the Vsys output pin? And is the Vbat pin isolated (not connected) to the Vsys?
Is it possible to even bypass the charger IC by using a supervisor and a FET to pass from the input to Vsys if the input drops below the minimum 3.9Vbus operation (which I assume the part will not operate)? Are there any reverse protection on the output for this case?
Thanks
Hi,
I'm getting frequent "JVM heap low detected!" warnings while doing MSP430 development. I recently updated my CCS install from 5.3 to Version: 5.5.0.00077. Prior to the upgrade I do not recall ever seeing a heap warning. I could step back to 5.3, but the debugger seems to be better behaved under 5.5, so I'd like to stick with it if possible. Is anyone else seeing this problem? Is there anything I can do to reduce or eliminate it? Ignoring it seems to lead to an eventual crash of CCS. I haven't tried increasing the heap size, but I'm just doing basic debugging, nothing fancy, so it's hard to believe that I really need a larger heap just to do MSP430 builds and debugging.
The host system is CentOS release 6.5 (Final), and the kernel is 2.6.32-431.el6.x86_64 #1 SMP. The target device is an MSP430F5308, and the emulator is an MSP-FET430UIF, version 1.4a.
I could shift to an Ubuntu 12.04 machine if that will actually help, but if 5.3 didn't have this problem under CentOS, I'm a bit surprised that it started showing up with 5.5.

Hi,
I am using custom board with F28069U and trying to Debug example usb_host_msc (controlsuite\v135).
I have connected USB flash drive to F28069 and can successfully read/write.
While testing, if USB connector is shaken or there is loose connection program goes into an endless loop shown below.
Even if USB is reset, connection is not reestablished.
unsigned long USBHCDPipeWrite(unsigned long ulPipe, unsigned char *pucData,unsigned long ulSize)
{
....
....
// Wait for a status change.
while(g_sUSBHCD.USBOUTPipes[ulPipeIdx].eState == PIPE_WRITING){} // here program gets in loop
....
....
}
or at
unsigned long USBHCDPipeRead(unsigned long ulPipe, unsigned char *pucData,unsigned long ulSize){
....
....
// Wait for a status change.
while(g_sUSBHCD.USBINPipes[ulPipeIdx].eState == PIPE_READING){} // here program gets in loop
....
....
}
This is my fourth post in forum with this problem, but I am not getting perfect solution. This is my pending issue for many times. please help me to solve this problem.

Currently, if no bluetooth 4.0 devices are detected by the sensortag within 30 seconds, advertising will stop and the sensortag will go back to sleep. I have to press the side button to re-activate it.
Hi,
I have two boards with a cc2520 on each one. I'm using the default configuration for GPIO4, which outputs sfd to the pin(GPIOCTRL = 0x2a). When I send a packet from one board to the other, I see that the receive sfd is delayed from the transmit sfd by roughly 3.3 to 3.5 us. I was expecting the two signals to be more closely aligned. What causes the receive sfd to be delayed? Will the length of this delay be consistent? I'm trying to time align some sample data that is sent between the two boards, so I would like to compensate for this delay if possible.
thanks,

I've downloaded the latest version of TI's SDK, ti-sdk-am335x-evm-06.00.00.00 and now I'm using AM335x-PSP 04.06.00.11 as my Kernel. The new version also changed the cross-compiler it uses, so I had to change the whole file system on my board to get the libraries my applications uses working.
One inconvenience, though, is that the bash is not as it used to be with the older versions of the SDK. After changing the whole file system, one of the most annoying things I ever saw started happening: the line on my terminal doesn't wrap anymore. Now, when I type a long line, it does not wrap to a new line as it should (and used to do). Instead, it just goes back to the beginning of the line and starts replacing the characters I already typed. The commands still work, but you can imagine the inconvenience.
It looks like this: if I type a long line, I would expect it to be shown like this:
[my prompt]$ ls -l file1 file2 file3 file4 file5 file6 file7 fi
le8 file9
And what actually happens is this:
le8 file9t]$ ls -l file1 file2 file3 file4 file5 file6 file7 fi
Worst yet, when I type the up arrow to go back in the command history, minicom (computer side) starts going up in the terminal I use (Konsole), erasing the previous lines every time there is a long command in the history. It's complicate to explain this issue, but it is more or less like a Carriage Return (\r\n) backwards, moving the cursor up (and not down).
I searched everywhere and the closest I got was some guy who had the environment variable PS1 wrong due to a color problem, but the PS1 line in /etc/profile haven't changed from the older file system to the newer. I also tried changing the terminal I use, first linux, then vt100, then xterm, but none changed this behavior. stty wasn't a lot helpful either (at least so far).
One final thing I noticed is that every file under /etc/terminfo/ is exactly the same on both file systems. That got me wondering if that is the reason why I can't get the terminal working. If I had to change the file system in order to get the libm working, for example, wouldn't it be necessary to re-compile every terminal with the new cross-compiler?
Is there any way to check if the terminal is working? So far I can just see which one I'm using echoing $TERM...
Anyway, thanks for the patience. An help would be really great!!

Question:
When adding elements to a Q, can I declare one Q entry, put it in the Q, and then rewrite the data of that object, and put it in the Q again?
For example:
void task(void)
{
Queue_record qEntry;
//etc declare vars
while(1)
{
for(i=0;i<8;i++)
{
newData = GIO_read();
qEntry->data = newData;
Queue_Put(myQ, &(qEntry.Elem));
}
Sempahore_post( processingTaskSem);
}
}
or, do I have to declare a new Q object every time I put new data into the Q?
Hello All,
I am using the Launchpad to read serial data from an instrument. Each reading from the instrument is prefixed with the '~' character. I am trying to read this serial input (via UART5). However, I have some trouble parsing this data. Here is the portion of code I am using:
int b=0;
int noofreadingstoaverage5;
while (b<noofreadingstoaverage){
//c=UARTCharGetNonBlocking(UART5_BASE);
c=UARTCharGet(UART5_BASE);
UARTprintf("%c",c); // echo character
if ((c=='~')||(c==126)) {
b++;
UARTprintf("\n%i",b);
}
}
The trouble is the input '~' is not being counted. So b remains 0. How do I fix this?
Thanks.

I have been working with the BeagleBoard xm with ICS running on it for some time now but I now need to switch to using Windows as my host machine. adb has been giving me some trouble. I have been able to successfully use my Android installation with an Ubuntu machine but I am having some trouble getting it to work with Windows7 64bit. I followed the instructions at
http://processors.wiki.ti.com/index.php/Android_ADB_Setup#adb_over_USB_on_Windows_Machine
but this is not working for me. After I plug my board in, to force Windows to let me manually select a driver I must go through the device manager and then select "Update Driver." From there I select "Browse my computer for driver software" and then find the altered android_winusb.inf file. This comes back saying that "Windows could not find driver software for my device"
I checked that the VID and PID used in my .inf file are correct with the BeagleBoard and Android installation I am using, and those do match up.
What am I missing?
Thanks,
Doug
I would like to use the EMIF16 of the C6672 as an interface for I/O devices such as FPGA. Is it possible?
Sysbios 6.37.00.20
BiosPSP 3.00.1.0
Just some background, I'm using Mcbsp with issue/reclaim GIO model to aquire a signal from an ADC. I have a heapBuf declared where I allocate a block, and pass the data to a DSP algorithm, which frees the memory after I've processed it.
I'm getting a "ti.sysbios.heaps.HeapBti.sysbios.knl.Semaphore: line 207: assertion failure: A_badContext: bad calling context. Must be called from a Task." error during runtime.
It seems the cause of this is usually due to having a Semaphore_pend in a SWI or a HWI. I've searched my project and all of my Semaphore_pend calls are located inside tasks. When the execution terminates, the ROV tells me that the thread type is Main.
I do see a pair of semaphores in the ROV that I didn't create, and they have no label. I know the GIO issue/reclaim uses semaphores, so I'm assuming that's what they are from.
This error occurred when I added some extra instructions to DSP algorithm. With some count variables thrown into the DSP algorithm, I see that it consistently runs 15 times before it errors out. First thought was that these extra instructions are causing the heap to fill up before I can process the data, but looking are the ROV, I have 2 allocated blocks out of 32 total... so probably not a heap full error.
However... I increase the heap to 48 blocks, and the algo runs 23 times before the error. A heap size of 64 will let the algo run 31 times before the error. In each case, the ROV says that only 2 blocks are allocated, but there seems to be a linear relationship between the number of blocks in the heap, and how many times the algo will run before the error is thrown.
Hello there,
I am having trouble in porting Bluetooth stack on TIVA 129X board
I am following some guidelines from this post but it doesn't help much as lack of knowledge in this Controller.
http://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/p/307474/1080723.aspx#1080723
I would require your expertise on this subject.

I'm configuring my MSP430F5438A Bluetopia Stonestreet One stack as a SPP server
with a PC connecting directly as a master based on BDADDR (no
pairing).
To detect connections from the PC I am handling etPort_Open_Indication
and etPort_Open_Confirmation events in my SPP_Event_Callback().
To detect disconnections from the PC I am handling
etPort_Close_Port_Indication events in my SPP_Event_Callback().
When the PC (running Bluecove's stack under Java) disconnects
gracefully (presumably with some sort of disconnect command - I don't
know the Bluecove stack or Java), I detect the disconnection just
find.
However, I cannot detect other types of disconnects, for example,
if I just pull the PC bluetooth dongle out. The Bluetopia stack
still thinks it's connected.
How can I detect "ungraceful" disconnects?

Hi, I would like to use the EMIF 16 Peripheral to link to an Altera FPGA. I want to know the maximum bandwidth for the EMIF 16 link. I'm looking over the data sheet for the TMS320C6655/57 on page 201 and 202 and Table 7-69 and the equation for Tc(CEL) (WS+WST+WH+TA+4)*E-3 is for the minimum time and the max time is (WS+WST+WH_TA+4)*E+3. The trouble I"m having is I don't know where to look to find the values for WS, WST, WH, TA and E. Does anyone know where I can find these values?
Thanks,

I am working with the F28M35x Concerto, and the RAM Management example provided by controlsuite (v201) seems to have some problems.
After importing the projects, and adding additional path variables, the M3 project still has a build error:
Description Resource Path Location Type
object files have incompatible byte orderings RAM_management_m3 C/C++ Problem
Also, the #pragma directives do not correspond to anything in the linker file. The pragma directives are:
#pragma DATA_SECTION(m3_r_array,"SHARERAMS0");
#pragma DATA_SECTION(m3_r_w_array,"SHARERAMS2");
Neither SHARERAMS0 nor SHARERAMS2 appear in the linker. The only linker command file in the project is F28M35x_Headers_nonBIOS.cmd, whereas searching in the forums seems to indicate that there should be another one. The M3 project does not have any linker files.
Any help in getting this project to work is appreciated!
Thanks
Hello,
I am running a simple transient test for checking overshoot and stability with OPA2188 driving a capacitive load.
The reason for that is OPA2188 will be buffering a 1.25 V as input reference for INA330, and datasheet of INA330 asks for a 0.1uF cap.
So here is the circuit:
Now, when I use a load (R1) greater than 250Mohms, curve goes ok, like this:
But if I use a load lower than 200Mohms, down to 50Mohms (give or take) a weird dip happens:
At 1Mohms curve goes back to "normal" overshoot.
Other input voltages also made output curve switch like this.
What am I missing??
Dear support,
We have Concerto F28M35H52C1 Loader M3 that prform M3-application programming.
But we have to program C28 firmware also and as result of it our loader should be dual (include M3 and C28 parts).
C28 firmware run from the flash only if its start address = 0x13FFF0.
FLASH : origin = 0x100000, length = 0xFFE0
BEGIN : origin = 0x13FFF0, length = 0x2
If I change this address to another one – C28 doesn’t start after booting.
FLASH : origin = 0x100000, length = 0xFFE0
BEGIN : origin = 0x10FFE0, length = 0x2
How to run C28 firmware with begin-address different from 0x13FFF0? How M3-loader/application know what C28 program to run (our C28 flash include two programs – C28 loader and C28 application)
Could you help us with it?
Thanks, Sabina

I tried to updated firmware using ROM_UpdateEthernet() function in ROM. I wrote the code as following:
void FirmwareUpdate (void)
{
// Set the clocking to run from the PLL at 50 MHz
// ROM_SysCtlClockSet( SYSCTL_SYSDIV_4 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN | SYSCTL_XTAL_16MHZ );
// Disable all processor interrupts.
HWREG(NVIC_DIS0) = 0xffffffff;
HWREG(NVIC_DIS1) = 0xffffffff;
ROM_SysTickIntDisable();
ROM_SysTickDisable();
//
// Clear any active interrupts. If the boot loader uses any
// interrupts, they will therefore respond as expected.
//
HWREG(NVIC_APINT) = NVIC_APINT_VECTKEY | NVIC_APINT_VECT_CLR_ACT;
ROM_UpdateEthernet(ROM_SysCtlClockGet());
}This function is executed inside a Task.
I configured LM Flash Programmer with with correct MAC addr. and then opened Tera Term and typed the cmd to update the firmware. The LM Flash Programmer starting programming. It is a good sign. However, It stopped during programming for some reasons. I believe some other Tasks crashed the programming.
I also tried use BIOS_exit(0) before FirmwareUpdate(). However, the FirmwareUpdate() wont execute.
Is there any solutions to successfully update firmware via Ethernet?
Thanks
