Question

I want to make a frequency of 750khz, 50:50 duty ratio. 
 How do I use pwm? 
 I use it. nRF52832 PCA10040 
 I used the PWM library example but it failed. 
 The frequency that I could generate was 1Mhz 500khz.

Hi, 
 With a timer running at 16 MHz, the closest you could get to 750 kHz would be 761.9 kHz, with a compare value of 21 (16 MHz/21 = 761.9 kHz) 
 Best regards,
