Konstrukce TV terminál s Atmega8

Tak díky té NE555 už jde přečíst signature toho procesoru. Ale divná je ta zapisovací doba. Pokud kmitá na 155 Khz, tak by dle mého měl zapisovat mnohem pomaleji. Zápis by měl probíhat 1/4 kmitočtu procesoru. V avrdude lze k tomuto účelu pravděpodobně použít parametr -i delay

Zde vysvětlení
For bitbang-type programmers, delay for approximately delay microseconds between each bit state change. If the host system is very fast, or the target runs off a slow clock (like a 32 kHz crystal, or the 128 kHz internal RC oscillator), this can become necessary to satisfy the requirement that the ISP clock frequency must not be higher than 1/4 of the CPU clock frequency. This is implemented as a spin-loop delay to allow even for very short delays. On Unix-style operating systems, the spin loop is initially calibrated against a system timer, so the number of microseconds might be rather realistic, assuming a constant system load while AVRDUDE is running. On Win32 operating systems, a preconfigured number of cycles per microsecond is assumed that might be off a bit for very fast or very slow machines.
