Hi, I am new to ARM, I am working with IAR in a Windows environment. I have been playing with it quite a lot and succeeded to learn quite a lot from the examples I found on IAR and the web. However, there is a few things I'm trying to figure out and I can't find any information about. First, the DBGU port. I have connected the port to a USB port in my laptop and opened up a connection using Putty. Nothing comes through. I am looking for some explanation on how to see the DBGU output. Second, I would like to open a USART port to send and receive messages. But all the examples I find are very complicated. I want to be able to send a message at certain events and receive messages from the computer. Does anyone know of simpler examples for such a project? Thanks a lot.
