I'm trying to implement a software that will allow me to send additional one pulse (on the data wire and clock wire). After one pulse I should send data (32 bits) over spi.
Frame should look like:
1 bit + 32 bit
clock pulse every bit
I tried to send 0x80 over SPI and USART but no luck - for 0x80 i have 8 clock pulses. How to implement one clock pulse? PWM? Timers? Dma?
I would be grateful for every idea !
