Hi!

I'm stucked programming with Keil environment as I didn't find any PWM example code for the EK-TM4C123GXL LaunchPad board.

I found some interesting code for Code Composer Studio (CSS) but I can't use it in Keil, could you give me some tips to do so?

Specifically it's about this Labs at TM4C123G_LaunchPad_Workshop:

http://processors.wiki.ti.com/index.php/Getting_Started_with_the_TIVA%E2%84%A2_C_Series_TM4C123G_LaunchPad

and the labs that are inside:

http://software-dl.ti.com/trainingTTO/trainingTTO_public_sw/GSW-TM4C123G-LaunchPad/TM4C123GLaunchPadWorkshopSetup.exe

I'm trying to use the PWM code in Keil but I can't use it.

Even better if you have code to run a PWM module in the EK-TM4C123GXL LaunchPad board.

Thanks!

P.S.: after searching several days in Internet for a solution for PWM module at a EK-TM4C123GXL LaunchPad board I didn't find any solution for Keil, so I think it needs a proper and good solution.

For the time investment understanding, coding and testing I found a bit more useful up to now doing by registers, also more optimized and resource control.

The advantage of using C API's is portability, readability, faster development time.

Hi Kel!

Thanks for your tip!

You are right, but as I just started programming with Keil based on registers, I'm more comfortable by now with it. I learnt it with the online edX course you saw I explain in Let's Make Robots and I started five months ago...

I indeed had a look on the Tivaware C API's (TivaWare_C_Series-2.1.0.12573 right now), and checked the example board's projects:

C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\ek-tm4c123gxl

I found them more abstract, even just starting from blinky.c to check how it works.

I also checked its documentation: TivaWare™ Peripheral Driver Library for C Series User's Guide

and its documentation at:

C:\ti\TivaWare_C_Series-2.1.0.12573\docs

But it's estrange how there is not a practical example for pwm with this libraries...

However I also believe that Tivaware libraries approximation has its benefits and I would like to try it, it i can have some guidance or tips about it.

Thanks!

Kind regards,

Francisco

Hi Kel and Amit,

I have started to use TivaWare C API's functions with PWM disable dead-band, but I'm finding an issue, maybe you can help me. As it's different from this thread I have open a new one here: http://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/t/344897.aspx

Thanks!

Kind regards,

Francisco

There are also PWM example codes at "\\examples\peripherals\pwm"

Hello Francisco,

Wise move. I would thank Kel for initiating it..

As usual the project files would be useful.

Regards
