Posted on November 19, 2015 at 18:32 Hello,
I'm wondering if it is possible like with the pic32 to initiate a DMA transfer from peripheral to peripheral. So far the documentation I've read specifies periph to memory, memory to periph, or memory to memory.
The idea is to forward every bytes from USART2_RX to USART6_TX and vice versa.
I'm currently doing it with interrupts, but I would like to lighten the MCU a little bit because it does a lot of things in background.
Should I use a small buffer in memory and do periph to mem, then mem to periph?
Thanks for your input.
Dan.
