Is this an ISP programmer for AVR or STM?
(lemmy.world)
Bought it a long time ago and can't remember. There's a jumper cable and I remembered using it to flash something. I only dabble with Atmega32U4, Atmega328p and stm32 blue pill, so it's probably either of them.
Or maybe my brain short circuited and it's a totally different hardware.
I actually needed an AVR flasher to fix a pro micro with corrupted bootloader that cannot enter dfu mode. So I want to make sure I don't have it before buying a new one.
Thank you!
Neither. It's a USB-to-Serial converter with what might or might not be an FTDI chip.
Thank you
With some finagling, I believe ATMegas with the Arduino bootloader can be programmed using straight serial - you just have to time the reset pulse carefully.
I don't think you can use it as an actual AVR programmer for new bootloaders, fuses etc. though. You need a full MCU for that. If you have a spare Arduino or ATMega that is happy, you can use 'Arduino as ISP' to do it.
