#156609 - The real problem is... Responding to: ???'s previous message |
...that these stupid, ridiculous, handmade programmers very often do violate the programming specifications of flash micros! So, for ISP programming, for instance, it's of ultimative importance to have the reset line logic high during power-up and power-down, at least for the AT89S52 and similar. I don't know any of these crap programmers which provide this. Only the ATMEL's ISP programming cable does it, to my knowledge. For this I have measured and verified it.
Keep your hands off this crap and buy something useful, especially if you are so unskilled, that you even don't know what a decoupling cap is. Kai |
