PWM and Softdevice

[Oscar]

Hi,

I am trying to get the PWM example (github.com/.../nrf51-pwm-library) to work with a Softdevice (S110) that advertises.

There have been several Questions on the topic, but I still don't understand how I make sure that the timer used to trigger the PWM is placed through the sd_ppi event management.

Two different setups:

1. Only using the example code quoted above works fine, as long as I keep #define USE_WITH_SOFTDEVICE
0 When set this to 1, the PWM doesn't work anymore. As far as I understand (following this question), this is due to the SD not being initialised. Thus, I moved to the second setup:
2. I copied all of the PWM example into the nrf6310\s110\ble_app_template example. Now the SD works fine, but the PWM does still not trigger. I then increased #define APP_TIMER_MAX_TIMERS by one (as I thought would be the additional timer for the PWM and then uncommented err_code = app_timer_start(m_pwm_timer_id, PWM_INTERVAL, NULL); in the function timers_start(void).

But that still does not work. I am still missing something, could you please help me, what?

Thanks!

Edit: To make things clearer, please see my main.c, where I tried to put together the BLE_template and the PWM example. It advertises, but the PIN20 is not toggled by the PWM.

Anybody can help?

Found it!

I chose the max_pwm value too low compared to the actual values in the pwm. As such, nrf_gpiote_task_config was never called and after the first interrupt no task would be scheduled.
