Hi,
Last time i worked with ATMEGA32 I Accidently Programmed my Chip (in ISP mode) Wrong and
i Disabled the SPI Enable fuse Bit and i think I had programmed my Fuse bit Wrong that i Can't Program
(read or Write )My chip any more(i checked it with ISP Programmer).
Is there any solution To Change My fuse bits and unlock the chip and make it usable for further programming .
Some One told Me Programming ATMEGA32 in High Voltage Parallel Mode will Help me to Change the fuse bits .is it possible ? If So Please Send the schematic and software.
Hello!
That is right. u can enable the serial mode by programming the microcontroller in parallel mode. I made the same mistake with ATmega8. I worte a program for Pic16F877 and reenabled the serial mode of programming by only reprogramming the fuses of ATmega8. Just read the pdf of the controller, write a program for 8051 or any other controller and reprogram the fuses(remember just the fuses,no need to program the whole microcontroller).
Regards.
