Part Number:TPS57060-Q1
Hello Team,
we need more detailed description about the internal switching frequency tolerance of our part:
In our datasheet there is a range of 450 to 720kHz for Vin=12V and RT=200kOhm.
Is this including a resistor tolerance? and which value?
What about the complete Vin range of the device? Is there also a change?
There is also a chart available about junction temperature but only for Vi=12V and RT=200k. What about deviation across Vin and RT?
Many Thanks
Josef

I imported spp_BLE_server_cc2650lp_app from GitHub Example 2.2 into ccsv9 with both boxes checked for "Automatically import referenced projects found in the same directory" and "Copy projects into workspace". There are no issues building spp_BLE_server_cc2650lp_app.
I used copy/paste on project spp_BLE_server_cc2650lp_app and renamed the project GENII_spp_ble_server_cc2640genII_app. I used copy/paste on the CC2650_LAUNCHPADXL folder to create a new CC2640_GENII folder so that I could modify the board files. I changed a Predefined Symbol from CC2650_LAUNCHXL to xCC2650_LAUNCHXL and added CC2640_GENII. The only other changes I made are to pin assignments in the board files.
When I build GENII_spp_ble_server_cc2640genII_app, I get one error "#20 identifier UARTCC26XX_HWAttrsV2 is undefined." I have verified that my CC2640_GENII.c file is identical to the CC2650_LAUNCHXL.c except for the filename.
I put my modified board files into the CC2650_LAUNCHPADXL folder and I get the same error.
I'll be darned if I can't figure out why this one constant is undefined in my copied project but not the original. Maybe there's a path somewhere that I need to update, but where?

Hi,
I tried to debug my code using "xds 200 usb debugger" in the target board while i started to debug there was no error, while i tried for the second time i got "target device in low power mode" and then cannot debug,
this thing continues for so many iterations initially board gets detected after a 5 to 10 seconds delay board gets into target power loss mode. Kindly help me to resolve this
Thanks

I'm using AM3358 SoC on Beagle Bone Black compatible board. I want to use DM timers (timer 6 and 7). But I can't read from timer 6's control register. I do it the following way:
.....
#define TIMER6_BASE_REG 0x48048000
.....
....
printk(KERN_INFO"!!!Trying to read Timer6 register manualy with readl...\n");
printk(KERN_INFO"!!!Timer6 control register address:%x...\n",TIMER6_BASE_REG + (OMAP_TIMER_CTRL_REG & 0xff));
void __iomem *io = ioremap(TIMER6_BASE_REG + (OMAP_TIMER_CTRL_REG & 0xff), SZ_4K);
printk(KERN_INFO"!!!Remapped address:%x...\n",(unsigned long*) io);
printk(KERN_INFO"!!!Trying to read...\n");
....
//omap_dm_timer_enable(cpts->odt);
//omap_dm_timer_enable(cpts->odt2);
unsigned int address = 0;
address = readl(io);
printk(KERN_INFO"!!!Value:%x...\n",address);
printk(KERN_INFO"!!!Reading done succesfully...\n");
This causes page fault as far as I understood. Here is dmesg output:.... [ 116.075307] !!!Trying to read Timer6 register manualy with readl...

I tried to read from ethernet registers the same way (from 4a100000 physical address) and it's working fine... My guess was that I couldn't access the DM Timer control register because the timer itself (or the clock of the timer) were not enabled and I tried the following before accessing register:
omap_dm_timer_enable(cpts->odt); omap_dm_timer_enable(cpts->odt2);
Also I tried to comment the following string in /drivers/clocksource/time-ti-dm.c in omap_dm_timer_prepare function:
//omap_dm_timer_disable(timer);
Nothing seemed to help...

Part Number:CC1352R
Hello,
I am using CC1352R REV E boards with SDK3.0.1.
I followed these guide dev.ti.com/.../dmm_integration.html.
I followed complete steps successfully and ran both example i.e. rfSensor and ble5_simple_peripheral_cc13x2r1lp_app.
As mentioned in these guide i opened two UART ports one is for "BLE" and one data port is for "Collector".
The output on BLE port is fine but i am not able to see anything on "Collector" data port and
also when i am trying to connect through "Light Blue" mobile app i am not able to connect it and showed these message "No Data available" on mobile app.
So,Can you help me in knowing how to resolve this issue?
Thank you,
Kartik.
The most common example of this question comes from the fact that Standard Logic devices are specified at 1.65V, 3V, and 4.5V, however most engineers use our devices at 1.8V, 3.3V, and 5V.
Supplies are not perfect in any system -- they can fluctuate up or down significantly. MOSFET resistances increase at lower voltages, so the datasheet specifications are not tested at the nominal supply values , but at approximately 10% below nominal. I can't tell you why it's not exactly 10% -- these values have been used for decades and have become standardized throughout the industry. At 5V, it's exactly 10% (0.5V), but at 3.3V it's rounded to ~9%. At 1.8V it's ~8%. My assumption is that these values were rounded a bit to give easier values to work with -- 1.62V isn't as "nice" of a number as 1.65V, and in the end, they both achieve the same goal, which is to provide a 1.8-V supply lower limit for testing.
In many cases, the best option is to use the datasheet values for your design -- even if you know your supply is exactly 3.302V and will never change. They provide a 'worst case' value that will prevent errors in the design.
If, for some reason, you really need a value between those given in the datasheet, linear interpolation is the TI approved method for getting intermediate points. You might be saying "but not all those specs are linear" -- and you'd be right. The fact is though, that across a small range (for example, between 1.65V and 3V), the variation from linear will be minor, and the datasheet values provide some headroom to the specifications. This method gives a safe approximation that is backed by TI and our characterization process.
The equation for linear interpolation is:
Most typically, the "x" values will be the supply, and the "y" values will be the spec, with "y" being the value you are trying to get, and "x" being the specific supply value at which you are trying to get it.
I have already implemented this into an example Excel file if you would like to use that:
(Please visit the site to view this file)
If you need values beyond the datasheet specs, for example, if you need a 5.1V value and the datasheet only gives 3V and 4.5V values, then linear extrapolation is used. The equation and method are the same as above, except your data point will be outside the range of the given supplies. I would recommend only doing this for values very close to the given datasheet specs, since this method becomes more inaccurate the farther the supply is from the given values.

Hi,
When I use my code inside the first 64k everything works fine. But If I start moving data above it, I got strange behavior.
The default memory model is large so that is not the problem.
Any suggestion what can cause this?
I use compiler: c2000_18.1.5.LTS
Thanks!
Part Number:MSP430FR5969
Hi
I am using MSP430FR5969 with Dual Image, One image for Application code and second for extra image.
At startup bootloader checks image CRC and starts application.
But I received some devices from field Dead and when i read code from Dead device using FET pro.
Then i compared with memory of healthy device and i saw some bytes changes in FRAM section where code is saved.
So under what conditions this can happen, because this is memory where actual code is saved.
Please help.
Thanks in advance

Hi All,
I'm working with EVM430F6736 energy meter. Software part: For calibration of energy, to set the energy threshold like (#define ENERGY_100MWATT_HOUR_THRESHOLD (SAMPLES_PER_10_SECONDS*3600L*10L)). If the accumulated energy is greater than this threshold means, energy consumed to be incremented. The accumulated energy attained the threshold level for every 10 seconds. How the energy threshold is fixed?. ( I referred the EVM development board document. As per the document, this threshold calculation isn't same. In document, it takes samples / sec. Here in this software, samples per 10 sec. )
Thanks & Regards,

Part Number:MAX3221
Hello,
we use a MXA3221CPWR and have problems in the series.
It happens again and again on some boards the -V voltage at the MAX3221 is only -1,5V. The boards come from our PCB assembler and put them into operation in an ESD environment and assemble the device. The IC does not break soft, but during production. The default rate is about 20%. We exchange the IC after that everything is OK again. Do you have any advice as to what could happen.
Many Thanks
Hello everybody.
I have such a question.
I worked with 'MULTIROLE' project on cc2640r2f. It handles multiply connections to cc2640r2f board.
Also I 've got HID keyboard example also using with cc2640r2f, but only with one device connected.
My question is, does it possible to mix this two projects to have cc2640r2f as a HID keyboard, to which can connect up to 4 devices (mobile phones)
and it can act like a HID keyboard simultaneously for all this devices in one time.
All my best.
Ivan.
Part Number:TMS320F28067
Hello,
colleagues of mine identified that the CAN communication stops in a test setup at a random time with a TMS320F28067 processor. We connected to the non-communicating CPU via JTAG (without loading a new firmware image and also without resetting the CPU in order to preserve the error situation).
We use Mailbox 0 in Tx direction. We see that Mailbox 0 holds a message and the corresponding transmit request bit inside register CANTRS is being set but never cleared by the peripheral. So it looks like the CAN controller stops transmitting the message located inside Mailbox 0. We also measured via oscilloscope that the CAN_TX pin of the CPU has always a high level, so no messages are being transmitted.
Here is a screen-shot of the relevant registers:
The registers that we checked are:
CANME = 63 -> Mailbox 0…5 are enabled.
CANMD = 62 -> Mailbox 0 is selected as a Tx Mailbox.
CANTRS bit 0 -> TRS0=1, which means a transmit request has been set for Mailbox 0. We expect this bit to get 0 after the message is being shifted out but this never happens.
CANES = 16 -> No power down or bus-off state. So no error indication that would prevent a transmission of a CAN telegram.
CANTEC = 0 -> No transmission error.
CANTIOC = 9 -> CANTX pin is used for transmission.
CANTSC is incrementing, which means CAN controller is clocked.
Can you please help us to check why the CPU stops suddenly shifting our messages on the CAN bus? Is there any further register we can look at?
Best regards,
Andreas

Hello,
I have a project to charge 24V lead-acid batteries. I am not sure whether BQ24650 can meet my needs. I watched the process of lead-acid charging. When the overvoltage of lead-acid batteries is 29V in the process of overvoltage charging, I hesitated a little whether BQ24650 can meet my needs. If not, can you recommend other charging chips that can charge 24V lead-acid batteries?
Part Number:BQ28Z610
Team,
Are there ways to read the BQ28Z610 registers to identify which "system level protection" have kicked in?
For example can BQstudio + EV2300 / EV2400 be used for that? Or do you need an external MCU board to run customer SW to access I2C?
Can the EV2300/EV2400 connect to a custom board or only to the EVM?
Are the some guidelines on how to debug problems during developments?
The actual problem manifest itself with the BQ28Z610 that open/close the FET at a 25ms rate that make the pack voltage level oscillating between 3.8 and 4.2V:
Thanks in advance,
A.
