Part Number:UCD90160A
I am having an issue with connecting to the UCD90160A. When I select Fusion Designer Online I get a "No Device Found" error.
I had a telecon with Russ W. recently 5/1 and I do not remember what we did to fix this one. My address bins are 8 and 8.
I can see the SCL and SDA lines are toggling but the program gives me a "No Device Found" error.
Part Number:OMAP-L138
I am using the ARM of the OMAP-L138
Code Composer Studio 5.5
I am using SYS/BIOS
Target processor version is set to 5e
Designate code state is set to 32
Floating point support is set to VFPv2
When I change floating point support from vfplib to VFPv2, I get the error:
Tag_ABI_VFP_args attribute value of "0" that is different than one previously seen ("1"); combining incompatible files
If I remove some of the functions that use floating point numbers, I do not get this error. I read some of the previous posts about this error. Most of them talk about using a library that was not compiled with the correct flags. I am not using any libraries like that.
If I try to use --diag_suppress=16004 then my code crashes and says “ti.sysbios.family.arm.exc.Exception: line 180: E_undefinedInstruction:”
Is there something else that I need to do to use the floating point coprocessor of this ARM 9E? Thanks.
Part Number:PGA281
In PGA281 data sheet "logic low threshold" minimum for "digital I/O" (see datasheet pag 5).
Datasheet reporting 0,1V as minimum voltage, is it possible to connect the pin to GND directly? Or it would be necessary to use an impedance to GND? In affirmative what value of impedance? Can someone please give us confirmation quickly as customer has been waiting with no replies. Thanks.
Part Number:CC2640R2F
I am using CC2640R2F as a network processor that communicates with our application processor. I am trying to set the SNP_GAPBOND_PAIRING_MODE to GAPBOND_PAIRING_MODE_INITIATE but it does not work as expected. I am setting this option from both the network processor and the application processor without success - the passcode request does not pop up on my phone app. I could only make it work if I am not using it as an network processor (using the simple peripheral example). Any ideas on how to solve this?
Thanks,

Hello,
I am trying to send integers over serial communication with the following PIC controlled LCD display
www.sparkfun.com/.../SerLCD_V2_5.PDF
I am using the UARTecho tutorial for the TI microcontroller, and attempting to send integers, because special integers/ characters are allocated for the PIC microcontroller to do things such as clear/ reset the LCD display.
I have been using the following library:
#include <ti/drivers/UART.h>
and the following code to send the data
UART_write(uart, 194, 1);
UART_write works with characters, but how does it work with integers?
Thanks,
Ben
Part Number:CC2640R2F
Tool/software: TI C/C++ Compiler
I am developing an application for the CC2640R2F based on the simplelink_cc2640r2_sdk_1_50_00_58 OAD example project.
I was able to port the application to my platform and had it compiling and performing updated over the air just fine.
However, when I added some C++ code that uses templates and some virtual functions, the project compiled, but would not link. A #10234-D error was generated and the console indicted the "Virtual function table" is missing. I would have expected the compiler to generate and include this table. Is there some configuration in CCS I need to do to get the compiler to generate/link this table during the build?
Note: The simplelink_cc2640r2_sdk_1_50_00_58 OAD example project uses compiler version TI v16.9.1.LTS

The DSP2833x_usDelay.asm file included with C2000Ware 1.00.03.00 has the following line of code:
.sect "ramfuncs"
The "ramfuncs" section was replaced by ".TI.ramfunc" in the F28335.cmd file provided with CCS v7.4.0.00015.
#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000
.TI.ramfunc : {} LOAD = FLASHD,
RUN = RAML0,
LOAD_START(_RamfuncsLoadStart),

#else
ramfuncs : LOAD = FLASHD,
RUN = RAML0,
LOAD_START(_RamfuncsLoadStart),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
PAGE = 0
#endif
#endifThis results in a Warning when trying to link the code because the "ramfuncs" is not defined when using a newer compiler:
"#10247-D null: creating output section "ramfuncs" without a SECTIONS specification"

Hi,
Our goal is to control a single-phase converter using the ePWM of DSPF28335 with CCSV7 and Matlab 2017b.
We are starting with 2 basic test: 1) by injecting only sine signal into the ePWM. At the beginning, the output signal is not giving the attending result and the high frequency switching disappears after 2 or three hours as shown in Figure 1 and 2;
2) Test by generating a control signal using a percentage including in the ePWM (CMPA=7500 which corresponds to duty cycle of 50 % and switching frequency fs = 5kHz). The output signal remains constant even after 1 day of operation. See the Figure 3 and 4.

I was recently asked to upgrade my development projects to CCS 8.0 and the latest compiler. 18.1.0 at the time. The port went smoothly until the compiler reached a module that contained class definitions whose member function declarations contained forward references to enum types. These modules compiled without errors with compiler ver 16.3 but starting with ver 17.9, they no longer will due to the forward declarations, (it generated a compiler fault because its use is non-standard).. I looked through the various compiler options but couldn't see any way to re-enable the ability, but couldn't find anything.
Is there a way to allow the compilation to complete or must I remove the forward declarations.
Thanks in advance,

Hi,
I'm having a problem importing examples from resource explorer to my IDE. I already downloaded the package and installed, but it seems that the program doesn't detect it, even in the resource explorer classic (but there I can manually add the MSPWare). There is a way that I can manually add the necessary packages to work with resource explorer?
Already tried to reinstall the package, to remove "tirex-localserver-3.1.3" that I read in another post (but this folder doesn't exist for me).
I'm using Windows 10 x64, CCS v7.4.0.00015.
Thanks and regards,
Helder
Part Number:AFE4404
I found an AFE4404 sample code from TI website that calculates the HR but no SpO2 calculation. Basically the SpO2 function call is commented out. So I am wondering if I can get the source code of the SpO2 calculation, as well as the all register configuration for the SpO2 using AFE4404. Thanks!

As the title suggests, I'm looking for email contact information for Field Application Engineer dealing with CC1352. If anyone from TI can help me get connected it will great. FYI I'm located in Dallas and would prefer to talk to someone who is local.
Thanks!
Part Number:MSP430FR2632
I am unable to get either UniFlash or MSP-FET to communicate with the microcontroller. I have double checked the configurations and tried both the 2-wire and 4-wire method with no luck. I also hooked up a generic JTAG and I don't see anything coming out of TDO.
The part is powered on 1.8V and is not drawing irregular power as far as I can tell. I double checked the pins and do not see an issue but I do not see the crystal oscillating and I do not have an output on VREG.
Please let me know if there are suggestions or things I should try. Very confused why it is not responding to anything.
Part Number:TMS320F28069
C2000 Team,
We have a customer observing something unexpected on the I2C Clock pin and the same kind of thing on a GPIO pin.
They looked at the I2C Clock and saw a spike on the rising edge. They scoped a different pin, configured as output, toggling with GPIO_writePin(), and see the same spike. (This is an F28069, and they have modified DriverLib from F2837x to support the F28069.) On the GPIO pin, the only thing connected to that trace is a 100 kOhm pull-up.
I’m attaching a couple scope plots so you can see what I mean. Is this something familiar?
Thanks,
Darren
Part Number:TMDSEVM6657
Tool/software: Code Composer Studio
Hi,
I'm developing a simple PCIe test application on the TMDSEVM6657LS eval board. I need to change the state of the PCIe CLK_MUX_SEL line controlled by the FPGA. The FPGA control register for this signal resides at address 0x50 in FPGA register space. Unfortunately, the versions of fpgaReadConfigurationRegister and fpgaWriteConfigurationRegister in the library Platform_Lib do not support register addresses above 0x3F. Therefore, I have to change the value of FPGA_MAX_ADDR_OFFSET (0x3F) in evmc665x_fpga.h and rebuild the library. This is where I've run into all sorts of trouble. What is the recommended technique for rebuilding this library? I've tried importing the Platform_Lib project into CodeComposer (V7), but that generated a ton of errors regarding missing #define parameters. Next I tried to build the project from the command line w/gmake, but that too was fraught with errors. Any suggestions would be greatly appreciated.
Regards.

Hi,
a customer is asking if during power up sequencing (where the 1.2V rail comes up before the 3.3V rail) the leakage from the 1.2V charging up the 3.3V rail to <1V is considered normal and safe operation.
Thank you!

Re: high accuracy lab
I understand part of the reason for multiple receive antennas so you can get angle. Why do your have multiple transmit antennas?
Per your tutorials:
S=4Ghz/40µS=100Mhz/µs=100e12
d=fc/2S=f*(3e8)/(2*100e12)=f*1.5e-6
The distance "accuracy" (i.e. <1mm) I think is 1/T where T=chirp time=40uS 1/T==25kHz
d=25e3 * 1.5e-6=.0375m=37mm which is >>1mm
Obviously, my math must be incorrect??

I am having an issue with Vacant Memory Access in my code. My code sometimes works fine for hours, sometimes stops at VMAIFG flag within 2 minutes and restarts. I want to know exactly which part of my code is responsible for this Vacant Memory Access.
I tried creating a watchpoint (and a breakpoint) on the address range of vacant memory and an ISR handler for SYSNMI. After that, I deliberately read a value from an address within the vacant memory. Upon execution, the watchpoint did stop my code but only after the code had already entered the ISR for SYSNMI. I wanted to catch the code at the point where I read a value from an address within the vacant memory.
Is there any way to detect the exact point in the code that causes the VMAIFG flag to switch on? Or is there any way to backtrace the code from a breakpoint/watchpoint?
I am using Code Composer Studio Version 7.
Thanks
Shaaina
