Making 4 regular PWM signal.

[JWY]

Hello, guys. I'm using the PCA10040 and the SDK 16.0's BLE UART peripheral example. I am trying to make PWM signal below.

When PWM0 stops, PWM2 works, and when PWM2 stops, then PWM3, and in the same way, PWM4 works. And this signal is constantly repeated.

I tried to implement it only with the PWM SDK example, but I thought I needed other things to make it works, so I asked a question. please give me an advise.

 

Thank you for reding my issue.

The simplest may be to use the nRF52833 and nRF52840 which have 4 PWM peripherals. You would need to configure all 4 PWM, and then delay the START for each of them with 200us, then they should produce the signal you show. That should be pretty straight forward I believe.
