Can you suggest any better solution other than bit banging

HI 

I have to sending a sequence of 768(96 bytes) bits to program a custom piece of hardware on a single data line. Initially the line is low for 500ns and then each bit is represented as a square wave with the timing as follows:- 

'0'  300ns High , 700ns Low     COuld possibly make High period 350ns , not sure if this helps

'1' 700ns High , 700ns Low 

Do you have any suggestions how I could possibly do this , I was thinking of bit banging a GPIO but I dont think I can get the required timing from the provided timers as it seems to only go down to resolution of 1us.

Also I have BLE running , would this affect the timers ?

Thanks RObin

If you are on NRF52x or newer, try using the PWM peripherial.

These are based on16 MHz clock frequency, and one of the "loading" modes can change the duration of each PWM period.
