Part Number:MSP430F5659
Hello everyone,
In our project we have a requirement that the MSP430F5659 will be flashed via UART (PIN P1_1,P1_2) also it can be flashed from USB .
For this requirement factory loaded bootloader is enough ? else what all are the changes needed in MCU side ?
or need a custom bootloader for this ?
Could anyone please explained on this, it will be very helpfull.
Kindly Help !
With Regards,

Dear all,
we are developing our own DLP Projector based on TIDA-01226. After minor fixed on the controller PCB we managed to start the projector (At least M_HOST_IRQ and S_HOST_IRQ leds are ON) but the DMD is not showing anything.
I attached the schematic for the DMD PCB for revision and I have few questions :
Schematic :
Questions :
1- On the configuration table there are 2 options (One for Master and one for slave). I followed those connection with the DMD. Is that ok ? Will the DMD start with the default firmware ?
2- We tried to set a test pattern on the DMD but we got reading error on the computer. Could that be because of a bad connection on the DMD side ?
Any help is appreciated

Hello,
I integrated the sensor controller generated code with an example project from Resource explorer. I have mentioned the app code below:
void capTouchTaskFxn(UArg a0, UArg a1) {
// Initialize and start the Sensor Controller
scifOsalInit();
scifOsalRegisterCtrlReadyCallback(scCtrlReadyCallback);
scifOsalRegisterTaskAlertCallback(scTaskAlertCallback);
scifInit(&scifDriverSetup);
scifStartTasksNbl(BV(SCIF_CAPACITIVE_TOUCH_TASK_ID));
// Main loop
while (1) {
// Wait for an ALERT callback
SemaphoreP_pend(touchSem, BIOS_WAIT_FOREVER);
// Clear the ALERT interrupt source
scifClearAlertIntSource();
// For each output buffer ready to be processed ...
while (scifGetTaskIoStructAvailCount(SCIF_CAPACITIVE_TOUCH_TASK_ID, SCIF_STRUCT_OUTPUT) != 0) {
SCIF_CAPACITIVE_TOUCH_OUTPUT_T* pOutput = (SCIF_CAPACITIVE_TOUCH_OUTPUT_T*) scifGetTaskStruct(SCIF_CAPACITIVE_TOUCH_TASK_ID, SCIF_STRUCT_OUTPUT);
if(pOutput->pTouchDet[0])
{
Led_toggle(0);
Led_toggle(1); // breakpoint 1
//GPIO_write(Board_PIN_GLED, Board_GPIO_LED_OFF);
}
if(pOutput->pTouchDet[1])
{
Led_toggle(0);
Led_toggle(1); // breakpoint 2
//GPIO_write(Board_PIN_GLED, Board_GPIO_LED_ON);
}
// Hand the output buffer back to the Sensor Controller
scifHandoffTaskStruct(SCIF_CAPACITIVE_TOUCH_TASK_ID, SCIF_STRUCT_OUTPUT);
}
// Acknowledge the ALERT event
scifAckAlertEvents();
}
} // capTouchTaskFxnThe above code works properly while debugging(when the two breakpoints are set or even when a breakpoint is set in the ScifAlertCallback()) It detects touch 10 out of 10 times. As soon as the breakpoints are removed, the responsiveness of the touch degrades significantly and it detects touch only 3-4/10 times. If breakpoint 1 is removed, touch 1 degrades but touch 2 works properly and vice versa. Please let me know if I am missing any configuration in Sensor controller studio. I have pasted the current config:

Hi,
I need CPU2 to use SCI. To do that I set correspondig bit, from CPUSEL5 register, to 1 using bitfield libraries. I would like to be able to do that using SCI driverlib module but I haven't found any API that does that. Can anyone tell me if there is one which does it?
I work with driverlib integrated in a SYS/BIOS project. But if I also integrate bitfield libraries then I get warnings of redefined typedefs. I think that if there is a specific SCI module within driverlib, it should have an API to select the CPU. I though this API would be GPIO_setMasterCore() but it doesn't work.

Adria

Part Number:BQ27510-G3
Hello,
i am just preparing the automatic testing and programming of series production of our boards with BQ27510.
The GoldenImage is well created as prescribed and I'm not sure if there should be a calibration of the Board Offset for every single board during the testing process.
I have understood that the CC-Offset is calibrated automatically.
What would you recommend? What makes really sense?
Best regards

Tool/software: Code Composer Studio
Hello, I'm testing Code Composure Studio v6 to see whether data of flash memory are same or different.
I compiled and debugged uC/OS-II both on Windows 10 and Linux(Ubuntu 16.04 LTS) using CCS.
But when I checked data of flash memory using Uniflah, there were somthing different... Most of data were same. Some were different.
Absolutely same uC/OS-II codes, ccs version(ccs 6.2.00050), compiler version(TI v18.12.1.LTS) on both OSes.
In this conditions, is it right to get different data depending on OS? Or something wrong?
Thanks.
Part Number:TMS320F28069
Dear all,
I'm working with a timer configured as one-shot (id=1). Part number: TMS320F28069.
Start mode:timer will be started by user.
Inside the ISR, I reload the period by calling the "Timer_setPeriodMicroSecs()" function with desired timeout. The value provided is between 1000 and 21000 usec. After that, I start the timer again.
Once in a while (May come after few hundred cycles and may come after hundreds of thousands of cycles), I get an interrupt about 80 usec after the previous one.
I'm sure (verified by debug tools) the value provided to Timer_setPeriodMicroSecs() at its last call, was at least 1000.
Please advise.
Alex.

Where can I find the certification number of the BLE chip? I want to sell our design in Canada, so I need to state: "Contains IC Number: xxxxxxx" on the product. Its FCC ID is 2AB6YHM-1011V1.
Thank you.
Part Number:LDC1614EVM
Hi Team.
I have been using your LDC1614EVM Inductance to Digital Converter to measure displacement on a simplified test model. I’m now looking to increase the complexity of my model and integrate the sensing coils into my test rig. However, would like to reduce the outer diameter of the coil size to 4mm and measure displacement on the micrometer scale (i.e. sensitivity of about 1um), within an aqueous environment.
My background is mechanical entering and have fairly limited experience with electronics. Is it possible to buy an integrated Inductance to Digital Converter Evaluation Module with the sensing coils that I can snap off that fit that description?
Thanks,
Abi
Part Number:TLC5940
Hello,
Is there a TI-maintained Python library available for interacting with the TLC5940 chip? I'm especially interested in Python libraries that allow Raspberry Pis to interact with the TLC5940.
I found at least two libraries on Github:
1) https://github.com/AidanHolmes/tlc5940
2) https://github.com/lrvdijk/tlc5940-raspberry
Which does TI recommend?
Thank you

My issue is that I do not undersetand how to retrieve the data using the BLE characteristics. In request , the guide says that I must indicate intent to read without sending any data. I do not understand how to do it.

Part Number:AM5708
Tool/software: Linux
Hi,
I'm using AM5708 based custom board.
We have SD card slot on MMC1 and EMMC mounted on MMC2.
Previously, we were booting with kernel 4.4.41. In that kernel, when we have SD card attached in our board, then SD card was detecting on mmcblk0 and EMMC was detecting on mmcblk1. And when SD card was not attached on the board, then EMMC was detecting on mmcblk0. So, we were always booting using mmcblk0 because our priority was SD card -> EMMC.
Now, we are trying to upgrade our kernel to 4.14.79. In this kernel version, even when SD card is not attached, EMMC is detected on mmcblk1. So, kernel is stuck at "Waiting for root device /dev/mmcblk0p2".
If SD card is attached, it is successfully booting from it, but we require to have both option (SD/EMMC) working so we can't change the command line argument for rootfs.
Is there any way I can put any fix in kernel to start detecting mmc like the previous kernel.
Thanks,
Gunjal
