I'm trying to communicate at 2.5Mbps using uart1 on mk10d.

I want to use uart1 and dma to communicate rs485 at a transmission rate of 2.5mbps.

After the data is sent, it takes approximately 30 us seconds for the response to start in slave.

At this time, the first byte fills up with 0x00 intermittently, so can you suggest a solution for this?

Hi @tj_P

Can you tell me the clock speed of you MK10? 120MHz, 100MHz, 75MHz or 50MHz.

Can you provide me more details please? What do you mean with " for the response to start in slave"? UART does not uses master/slave modes.

Best Regards, Miguel.
