Hi
I’m using LPC1837 running at 180MHz in my project, I need to use USART2,3 as high speed half duplex RS485 (baud rate = 6Mbits). I’ve configured my hardware and got it running up to 3Mbits without any problem but any speed above this receives incorrect characters in without any framing errors. i.e. if I transmit 0x55 I receive 0x5B. Has anyone come across this problem or has anyone got a suggestion.
Your help be most appreciated. Thanks
