TMDXICE110: ePWM issue

Kiselev Dmitry

Part Number: TMDXICE110
Other Parts Discussed in Thread: AMIC110

Hello.

I use TI-RTOS and I want to use the PWM module in AMIC110. Unfortunately, I could not find control and configuration drivers such as for GPIO, EMAC, I2C, SPI and another. How can I configure and manage PWM?

I found the starterware software in SDK, but it’s not yet clear how to integrate these pieces of code into the TI-RTOS.

Could you help me figure out how to start PWM? Maybe there are examples of simple projects, such as for I2C?

Hi,

GPIO, EMAC, I2C and SPI Low Level Drivers (LLDs) are documented here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/Device_Drivers.html#device-drivers

There is Starterware (bare-metal, no OS) code for ePWM located here:

<PDK>\packages\ti\starterware\dal\epwm.c
<PDK>\packages\ti\starterware\include\epwm.h

There is Starterware ePWM example code located here: <PDK>\packages\ti\starterware\examples\epwm

To build the example:

Environment setup: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_overview.html#setup-environment
cd <PDK>\packages\ti\starterware
gmake epwm_app_haptics_motor PLATFORM=am335x-evm (replace "gmake" with "make" if building on Linux)
Build result is located in <PDK>\packages\ti\starterware\binary\epwm_app_haptics_motor

I suggest using the Startware example as a starting place for your RTOS development.

Regards,
Frank
