6 PWM, 6 SAADC, Timers allocation question

[wpb3dm]

Hi, nRF52 Board, S132. Now, I want 6 pwm, 6 adc .

nRF52 has 5Timers, Timer0-Timer4. Now, I allocation these timers as follows:

//TIMER0 is used by softDevice

APP_PWM_INSTANCE(PWM1,1); // Create the instance "PWM1" using TIMER1.

APP_PWM_INSTANCE(PWM2,2); // Create the instance "PWM2" using TIMER2.

APP_PWM_INSTANCE(PWM3,3); // Create the instance "PWM3" using TIMER3.

static const nrf_drv_timer_t m_timer = NRF_DRV_TIMER_INSTANCE(4); // TIMER4

It can not work. But, if I remove the timer4, it can work normally. Why ? I have enable it in nrf_drv_config.h. #define TIMER4_ENABLED 1

Thanks!

Hi

Hmm, not sure. What does not work exactly? everything? does it not advertise, or does the PWM or SAADC not work? If you start the debugger and then stop the debugger(the red X in Keil), where is the execution at? Also try to enable Debug as described here and set a breakpoint in the error handler. If execution ends up in the error handler, then you can see in the call stack viewer where the error occured and the error code. Another error handling guide is here.
