HI,
I want to use the internal flash memory for my sensor example of the stack 15.4.Internally already functions developed to access the memory.
my question is in this example he used the ID's(system id,item id,sub id). like wise how many id's i can create and what is the maximum allowable data size for each id.
and is all the items stored sequentially

Hi,
I am using DRA7XX EVM board with DRA75 SOC. So I followed

RTOS/CC1310: Long range mode for CC1310
Part Number:CC1310
Tool/software: TI-RTOS
Hi,
This is regarding SmartRF Setting for Long Range communication using CC1310 Launchpad. I tested out with the 625bps legacy and the 2.5 simple link mode. Both gave similar range performance. In a dense non-LOS urban setting I was able to reach up to 300m and with up to 800m in clearer environment. I have the following question regarding the range improvement.
1. What is the difference between the two settings and which one is recommended?
2. I understand that lower data rate can provide longer communication range. What is the lowest supported data rate for CC1310?
3. How can I modify the 625bps or the 2.5kbps setting from the SmartRF setting to support even lower data rates. Something like 100bps of Sigfox, etc for increased range.
4. Is there some recommended SmartRF setting file that I can use for observing the longest possible range that the community here has tried?
Thanks for providing such an active forum.

CCS/CC1310: CC1310_LAUNCHXL_shutDownExtFlash() change PIN
Part Number:CC1310
Tool/software: Code Composer Studio
Hello Support Team,
i have a Problem with the CC1310_LAUNCHXL_shutDownExtFlash().
I want to shut down the external Flash in my application with this function.
My problem now is, that my colleague have made a mistake at our own designed Layout.
The GPIO 20 is used, to power up the coil of our relai.
So when i activate the function CC1310_LAUNCHXL_shutDownExtFlash(), the coil is powered up all the time, because the DIO20 is set High in the function.
PIN_setOutputValue(pinHandle, CC1310_LAUNCHXL_SPI_FLASH_CS, 0);
uint8_t i;
for(i = 0; i < 8; i++){
PIN_setOutputValue(pinHandle, CC1310_LAUNCHXL_SPI0_CLK, 0);
PIN_setOutputValue(pinHandle, CC1310_LAUNCHXL_SPI0_MOSI, (byte >> (7 - i)) & 0x01);
PIN_setOutputValue(pinHandle, CC1310_LAUNCHXL_SPI0_CLK, 1);
}
PIN_setOutputValue(pinHandle, CC1310_LAUNCHXL_SPI_FLASH_CS, 1);
I have to shut down the external flash, because the current consumption is otherwise to high in sleep mode with out it.
Is there a solution, to turn off the external flash, with out using the DIO20?
Thank you very much!
Bester regards

Hello,
my problem is, if I change the value in "EPwm1Regs.CMPA.bit.CMPAHR", the output "PWM1A" on the board but does not change.
That's why I want to ask:
Does not in the example "hrpwm_slider" need to define the MEP scale factor in the register HRMSTEP?
If so, where can I find this assignment?

Hi All,
I am working on CC3200-LaunchXL board with mqtt_client example as a reference to develop my final application.
Here in my application, i want to update the username, password along with other parameters of MQTT broker on user demand.
So to execute the above task, i am planning to use memory address to write and read address and use in my application.
I want to assign specific memory address to user macros or variable and which i can also update the data via serial communication.
If any one can suggest me, how to assign and read data it would be very helpful for me?
Thanks and Regards

BQ24072: Battery over discharge shutdown.
Part Number:BQ24072
Hi,
I wanted a battery charge managing IC for a typical 4.2V Lithium-ion cell. I was looking at the datasheet of this particular IC BQ24072, and found that it has over charge automatic shutdown, but couldn't find anything on over discharge protective shut down or any similar feature which will disable the battery from discharging below a voltage threshold.
Does this IC has any such feature or can be implemented using any reference design which is available?
Thanks

Hello! I applied the library Ti_aes_128. However, I encountered such a problem. If you use a function aes_enc_dec(*state, *key, dir) once, everything works fine. But in the second use, encryption occurs differently (if you look at the control known array from the example). Next and decrypts incorrectly. What could be the problem?

TMS320F28377D: IDDK_PM_Servo_F2837x project (III)
Part Number:TMS320F28377D
Hello,
We purchased the DesignDRIVE Development Kit IDDK v2.2.1 and I have a question on the IDDK_PM_Servo_F2837x project.
I am presently evaluating on the build level of LEVEL3 with the associated Estun PMSM motor.
I have connected the U,V,W phase wires of the motor to the main board and not connected any position sensor to the main board.
When I choose QEP_POS_ENCODER as POSITION_ENCODER and run the build level of LEVEL2 or LEVEL3, the project works fine.
Meanwhile, when I choose RESOLVER_POS_ENCODER as POSITION_ENCODER and run the build level of LEVEL2, the project works fine.
However when I run the build level of LEVEL3, something goes wrong with the project. The motor rotates around one turn and then stops rotating.
I can not figure out why the build level of LEVEL3 does not work fine when I choose RESOLVER_POS_ENCODER as POSITION_ENCODER.
How can I resolve this issue?
Thank you for your guidance.

CCS/CC2640R2F: XGCONF can't find import file
Part Number:CC2640R2F
Tool/software: Code Composer Studio
Hi all.
When I open file - app_ble.cfg with XGCONF, Code Composer Studio show me an error message:
```
Can't find import file: 'common/cc26xx/kernel/cc2640/config/cc2640_r2_csdk.cfg' (not found along '${WORK_SPACE}\simple_peripheral_cc2640r2lp_oad_offchip_app\TOOLS;C:/ti/xdctools_3_50_07_20_core/include;C:/ti/xdctools_3_50_07_20_core/packages')
```
I don't know how to fix it.
Here is my setting
----------------------------------------------------------------
Environment one:
IDE: CCSv8.20
SDK: simplelink_cc2640r2_sdk_2_20_00_49
Environment two:
IDE: CCSv7.40
SDK: simplelink_cc2640r2_sdk_1_40_00_45
Reproduce procedure:
1 open ccs with new workspace
2 import app/stack split project from SDK example list
for example, import project from
C:\ti\simplelink_cc2640r2_sdk_2_20_00_49\examples\rtos\CC2640R2_LAUNCHXL\blestack\simple_peripheral_oad_offchip
this will import three projects, bim, app and stack
3 open the window - project explorer,
and find the file app_ble.cfg in folder imple_peripheral_cc2640r2lp_oad_offchip_app/TOOLS/
4 now, right click on the file - app_ble.cfg, and choose "Open with XGCONF"
and you will see error message in window - problem
It shows :
---
Can't find import file: 'common/cc26xx/kernel/cc2640/config/cc2640_r2_csdk.cfg' (not found along '${WORK_SPACE}\simple_peripheral_cc2640r2lp_oad_offchip_app\TOOLS;C:/ti/xdctools_3_50_07_20_core/include;C:/ti/xdctools_3_50_07_20_core/packages')
---
Although, cc2640_r2_csdk.cfg is not found by XGCONF, this project still works well.
It is OK to build it, flash it, and run it on develop kit.
But this make me confuse while tracing XDC configuration.
Is there any way to fix it?
