Hi everyone,

Atmel's website offers application note AVR304 (interrupt driven software UART) and it has an included C code implementing the appnote. However, the example code does not use codevision, i've been trying to "convert" it to codevision syntax but i found i could not continue because the header files used are not for codevision. Does anyone have a software UART code written for codevison?

Im a begginer so i need to a code to start from.

Any help will do. Thanks in advance.

Hello xolang1

Do you actually need a software UART? there is already an on board UART and you can drive this under interrupt. It is much easier to use the onboard peripheral than to use a software UART.

hi marke,

Yes i do need a second UART. My design is currently connected to a PC via the on board UART. It requires another communications port to connect to another device. The appnote from atmel is really great but i haven't yet "converted" it for codevision. Maybe some one out there can help.



Thanks again.

Hello xolang1

Attached is the software UART ported to Codevision.
This is not fully debugged and tested, but is almost fully there and is something to work on.

Best regards
