It all depends upon your pain threshold. BASCOM/AVR has got to be the easiest development systems for the AVR out there. Great hardware abstraction, good support (The update wizard is a bit testy though) and lots of users. But it is basic. If you want to move to C then Codevision

Having some startup issues here with the M168 and new JtagiceMkII on an STK-500. I'm porting my bootloader from M128 to the 168, and I thought I'd take the easy way, and use a DIP 168 on the STK500. So after a lot of searching again, I finally found a ref to installing the 168 in

To Clarify - Bidirectional RS232 requires at least 3 connections - Rx, Tx, and Common or Ground. If your cable has no ground wire, it could have worked through the JTAG ground. Removing JTAG would then cause the RS232 to fail. Check your cable with an ohm meter or continuity chec

It might be a good idea to give some info on what crystal frequency you're using, what values you've initiated the UART registers with, and the parameters of the UART you want to use (e.g. 9600 N 8 1, etc.) Do you have hyperterminal set up for the same parameters? Zack On Mon, 14
