hi,

i have a signal to rate at 3mbit/s. The clock and signal are separate on two line.i tried to use connect EXTI on the clock. When i have a interrupt, i read the PIN where the signal's. This solution don't work.So, i want tu use the TIM external clock, and Input capture for read my signal. but this solution is more complicated.have you other idea?

SPI Slave, or Synchronous USART

My signal is continus and isn't a SPI format. is it possible to use the periph SPI for other signal type?

 if i use the synchronous USART, 

the

start bit and

stop

going to

bother me

because my

signal

will not have

the right structure

You say you have a clock and data signal, would seem like a good fit. Perhaps you need to be more specific.

I read more the datasheet and i think your solution is good.

I will tried this solution, monday.
