Hi, i've used arduino to program a lot of ATtiny85, no problems. Now i need more pins, then i need attiny84. Connect it to my arduino uno, recheck the connections, select Attiny84 8mhz in boards, load blink example ...
1- burn bootloader = no errors (the same output messages with attiny85)
2- upload sketch = no error (same output messages with attiny85)
and the led is not blinking. Check again, change to 1mhz for test ... same result. Have test with 3 attiny84, with an attiny85 (and selecing the board) it's working.
Why i can't get my led blinking with attiny84?
-try another attiny84 core
-check fuses are correct
-check reset pin is high
Here are some suggestions.
