STM CircleOS forum / USART problem with implementation

korczi · 2010-09-09 12:14:00

I'm trying to run USART1 without CircleOS. I've handled with TXE interrupt. When debugging i can see that when my program is entering USART_SendData Data is 0x2B witch is correct but state of USART_DR is not changing.
Have I forgot about something?

Please help it is very important for me to set this connection today

Be carrefull, the USART1 is connected to the IrDA on Primer2.
I'm not sure that you can read the DR register after write it. You only can read the received bytes.
Can you give us your code ?
