Hello
I want to configure the UART0 as an interrupt driven full duplex connection to my computer.
At baudrates up to 115200 sending and receiving works fine.
At higher baudrates following problem occurs: After getting an Receive Interrupt, in LPC_UART0->RBR is not the byte i have sent from my computer.
Sending data from the LPC1227 to the computer works fine, also at higher baudrates. So i think the baudrate is configured correctly.
My questions are:
What are the max UART0 baudrates of LPC1227 for sending and receiving? I can't find it in any datasheet.
Is there anything different at higher baudrates, when reading from the ReceiveBufferRegister in my UART0_IRQHandler .
Any ideas?
