Half-duplex one wire hardware UART on ATmega
You cannot short TxD to RxD and expect it to work because TxD is driven all the time and you will always hear yor own transmissions. To convert to half duplex you need a...

Multiple device targets in one project?
With a "Solution" in AVR Studio 5 you can have multiple related projects on the same set of source files. In those source files you have conditional compile blocks in them. In...

Asynchronous Serial TX
9600 baud is the right answer. The second part of what I said was that you showed seven 8-bit characters C0 00 3C C7 3C 87 00 So if the terminal was set to 19200, then each...

Assembler: Where are the labels ?
The AVR32 has no "native" assembler precisely because it was easier for Atmel to modify the open source 'as' than it was to roll their own from scratch. Forty years ago, in 1971...
