Programming Atmel Atmega 8L

programming atmega8

Anyone have experience in programming Atmel Atmega 8L for serial data communication? What I want to do is just programming the Atmega to receive and send data to the serial port of a computer. I have already written a pc program to send data to serial port but I don't have any idea in programming the Atnega.

Any ideas are welcome. It is great if there are sample codes.

hi,

what do you want to use ?

C Compiler or Assembler

TX/RX via interrupts or polling mode?

programming in atmega8

I prefer Assembler, and I have to comparing using interrupts and polling mode operation.

I have downloaded AVR Studio 4.0 from the website of atmel. Is it the right tool for developing program for atmega8L??

atmega8 interrupts

take a look at the application notes from atmel

Interrupt driven UART:

With the AVR Studio u can develop our program and test it with the simulator

i think you'll get good information

Hi SC/MP,

Your information is helpful. I am now studying the boot loader.

atmega8 uart assembler code

hi guys i need your help

i have a ATMEGA8-16PI already programmed, and i want to extract from it the corresponding code because i want another PIC with the same code and features for a college project.

how i could extract the code from it in order to program another ATMEGA8-16PI 28 pins?

any suggestion will be welcome
