atmega8 and rs485

[sherazi]

. i am new to usart programming... and i have to impliment a program that has to run on atmega8 and communicate to a far off (more than 50 m in some cases)trminal. i plan to use the 485 standard... and plan to code in asmbly...

can any one help in coding... i have never coded for usart befor... i would have to send the status of gate,(opneneing, closing, closed etc)from the control panel of gate opner to the terminal

Can't help with this directly, but why not program in C? There are libraries to do all the serial comms stuff.
