Hi everybody,
I wanna know if its possible to use DMA SPI for drive the ADS1256 or similar where I can "stop" the tranfer to wait until the time to convert T6 (Delay from last SCLK edge for DIN to first SCLK) of the ads.
I tried a interrupt in TX (with a TC flag and a fuction hanlder) but it wont resolve the problem, the SCLK doesnt stop.
