Hello,
I have one question. I have two CPUs (STM32F407 + STM32F103) and I need to "share" (or better say "synchronize") 64 bytes between these CPUs every 100us. So every 100us the CPU must send 64 bytes to another CPU and also read 64 bytes from the second CPU. Is it possible to do with DMA without any CPU load?
Thank you
Petr
