PORTC of microcontroller is not working
This tutorial is taken from the book MY EXPERIENCE IN PROGRAMMING AVR MICROCONTROLLER IN C USING WINAVR/AVRGCC. you can download it free from the files section(FILE-AVRBOOK.RAR) of yahoo group-booksbybibin http://groups.yahoo.com/group/booksbybibin/ comments about this book on www.booksbybibin.blogspot.com DISABLING JTAG After disabling JTAG you can use PORTC properly. Pins C2,C3,C4,C5 are set for JTAG When I brought my new microcontroller for the first time I thought that the microcontroller was not good because PORTC pins are not working, then I later came to know that it is due to JTAG only. Here is the fuse setting to disable jtag
