#108680 - Mine works with LS Responding to: ???'s previous message |
I do rememmber that mine had worked wit both HC and HCT . I also rememmber that I've tried to use a LS541 someday.
But those seried resistances are a must. I was not aware that you have built the Asim Khan's circuit! . About The postscript problem try to search for a postscript Viewer software , then you can print out that PCB. Still we need to look into the schemaic of your target board(the board with your AT89S51) and see how did you managed to connect the SPI lines. Farshid |
