hello guys! im new with arduino, i have bay the arduino uno with mega328 chip!
i have also some mega8 chips blank!
please tellme how to program the bootloader on blank chips and if i can use this on arduino uno board!!!
i have a usbstk500 programe and i have work with codevision!
can i aupload the boot loader with this programme if yes please send me instructions!!!
Yes, you can burn bootloaders onto them.
You will need a solderless breadboard, 16 MHz xtal, two 22pF caps, 10K resistor, a 100nF cap, and some jumper wires.
Read this thread regarding burning of bootloaders
You will download the sketch from the thread above and run that to download a bootloader into a blank part.
yes works thanks i have burn on mega8 chip
also i have upload the bootloader with codevison chipblaster programer by open the hex file D:\arduino-0022\hardware\arduino\bootloaders\atmega8\ATmegaBOOT.hex
and set manual the fuses to bootrst=0 bootsz1=0 bodlevel1=0
and this works well but i dont know if is the correct way!!!
one more question exept mega8 i have mega88pa, mega32, mega16, and mega8535,
in this chips can i upload the boot loader?? if yes what file and fuses can i use??
"mega88pa, mega32, mega16" For these I think yes.
mega8535 - maybe. It looks similar to atmega324, with less memory.
Can't help you on the fuses, need to look them up on the datasheets.
