lf352 Programming the AVR microcontroller with GCC libc 1.0.4


Posted on Feb 6, 2014

The AVR 8-Bit RISC microcontroller from Atmel is a very common microcontroller. This microcontroller is one chip with EEPROM, Ram, Analog to Digital converter, a lot of digital input and output lines, timers, UART for RS 232 communication and many other things. I wrote already in March 2002 an article about the same subject. A lot of things have c

hanged in the avr-libc development and the AT90S4433 microcontroller which I used in 2002 is no longer manufactured by Atmel. This is therefore an update of the March 2002 article. I will use libc-1. 0. 4 and the ATmega8 microcontroller. Many people where interested in microcontroller programming after the article which I wrote in 2002. However this first step to get the development environment up and running is the hardest. If something does not work then you have absolutely no clue where the fault is. Programmer cable wrong Circuit faulty Installation incorrect Parallelport disabled in bios Kernel modules for ppdev compiled wrong There can be a lot of reasons why things don`t work. To make the entrance to the exciting world of microcontrollers easier shop. tuxgraphics. org offers now a bootable CD with a manual and the programmer hardware. All you need to do then is boot from this CD and everything is up and running. No software installation is required and nothing is modified on your local computer. Even I use such a CD now for a while because the hardware I build often survives several generations of kernels and software installations on my PC. If I want later on to update some microcontroller software then I do not have to worry if the development environment on my Linux PC is still working. I just boot from the CD and it is up and running. Independent of this CD I will explain the installation of the GCC avr...
