Hello guys,
I have a mind-blowing problem:
Situation:
Trying to upload the classic blink sketch to ATtiny84A chip with my USBtinyISP programmer in Arduino IDE.
Settings:
- Board: ATtiny84
- Processor version: ATtiny84A (according to my chip)
- Programmer: DIY ATTiny: USBtinyISP
- Proc. Speed: 8MHz internal.
Ctrl+Shift+U --> rc=-1 error
I checked the wiring many times.
And here comes something interesting:
- I can program the chip via an Arduino NANO board
- I can program an ATtiny13 chip via USBtinyISP
Where is the problem with the combination I need?
Thanks for any help!
