Hello all,
I'm new here and in the Arduino's world!
I have one question, hope you guys can help me...
I have a .hex file to stuck into a Atmega8... I search a lot on the net, tried to build several programmers to put the program inside the Atmega8, but all the DIY stuff I reach if for Paralel ports or RS232 serial ones... nothing in USB... I tried an old pc too, that have some serial port, but one time is the hardware don't work, othe the software don't find the AVR... well it´s a mess...
Tthe program is a simple multimeter (Voltimeter, amperimeter and measure power and etc) for a Regulated DC PSU 0-30V. The goal is to display in a 2x16 row's LCD... and I just can't put the damn program inside the Atmega8...loool
I bought the Duemillenove Arduino, and I need to know if I can switch the Atmega 328 by the Atmega8 and with another software like AVRdude or PonyProg, stuck the program in the chip!
Any Ideas???? I'm trying to don't to program from the beggining another AVR as long I already have a .hex file tested and running
No need to have a special programmer with ARDUINO, that is one of the MAIN reasons why the Arduino solution exists. It does not need a special programmer because it has a serial bootloader onboard.
If you are talking about HEX files, you are talking about PLAIN OLD AVR chips with no bootloader... and those require you to have a special programmer. Installing a HEXFILE into an ARDUINO (BOOTLOADER enabled chip) will make it an EX-Arduino. You will have to program it with an external programmer like TINYUSB if you have no serial or parallel ports.
Well, if I had to program the AVR, once I finishing programming, Could I take the Atmega328 from the Arduino and stuck into my board? regarding of couse if the pinout is the same...
