Hi Everyone,
I hope this is the right section to post this.I would like to create my own circuit to program ATTiny45 and Atmega8 chips.
I have an FTDI cable and would like some guidance to what circuit is required.I was hoping I could connect RX to MISO and TX to MOSI directly, but it appears I need other components.
Many thanks,
Justin
A FTDI cable/module/or board mounted can only program avr chips if there is already a bootloader burned onto the chip. What is required if not using a bootloaded chip is a AVR harware programmer. Note that one simple AVR programmer is another arduino board running the IDE example sketch aruinoISP. Then wire the SPI pins required between the arduino board and the chip to be programmed.
