No cześć.
Sprawiłem sobie programator USBasp 2.0 w celach oczywistych. Podpiąłem go do ATtiny85-20PU aby wgrać program korzystając z avrdude i nie ważne, co bym wgrywał - dostaję ten sam błąd:
avrdude: verification error, first mismatch at byte 0x0000
0x00 != 0x29
avrdude: verification error; content mismatchKwarc 8 MHz wraz z dwoma kondensatorami 15 pF są wpięte tak, jak na schemacie w dokumentacji ATtiny85 (p. 6.2.6). Dodatkowo jest elektrolit 22 uF między VCC a GND.
Próbowałem programować 3 sztuki ATtiny85 - na każdym jest identyczny błąd. Przy ATmedze 8A oraz 328P wszystko jest w porządku.
Próbowałem zewrzeć w programatorze zworkę JP3 (Slow SCK) - bez skutku.
Co robić?
