What? Why couldn't an MCU interface with my computer? It's not like it has special electrons or something in it. I regularly program atmega chips with a cable I made that plugs into the parallel port on the back of any computer that has one. If you have a couple GPIO pins on a motherboard, you can probably program almost any MCU with with it.
The only exception is if the motherboard GPIO was say 3.3v and you had a 1.8v only MCU, but level shifters aren't exactly expensive.
- ticklemyelmo 5y agoSo do you jam the chip into the parallel port? Or do you...use an adapter?
- selcuka 5y agoI don't see the difference if it's just a parallel cable. Do you jam an STM32 into a USB port?
