#108637 - HC is wrong. Responding to: ???'s previous message |
Dear Abhishek,
Atmel Adapter uses 74HC244 that doesnt work with all PC parallel ports some newer pc ports use 3V signals and this is where HC244 fails. To avoid problems HCT should be used. Asims programmers works very well, I have used it myself. Regards, Prahlad Purohit |
