ChibiOS Free Embedded RTOS

Hi,

I would like to be able to change the usage of a timer at run-time between GPT and QEI (encoder). Both are not used at the same time.
I know that QEI is not (yet?) part of ChibiOS HAL, only ChibiOS-Contrib, but as a general question, is it possible to change the usage of a timer at run-time?
My issue for now is that if I enable both GPT and QEI on the same timer in mcuconf.h, I get the error:



So, do I have to comment out this check in the ChibiOS source code or is there a workaround for that issue?

as of my knowledge: timers are defined/assigned statically to either the

• GPT (gerneral purpose timer),
• PWM or
• ICU (input capute unit - to measure duty cycles)

driver; and that assignment can't be changed / dynamically assigned during runtime.

Correct, timers assignment cannot be changed dynamically.

Ok, thank you.

I will try to use another timer for GPT. A basic timer like Timer6.
