#101013 - AT89S8252 programmer Responding to: ???'s previous message |
Hello Slobodan Mandaric,
Its great to hear that you were successful in making your own programmer. Well I have tried a couple of times to program AT89S8252, using my own programmer. But failed everytime. So finally designed a programmer for AT89S51/52. Its working good. I have followed a little different sequence from what is given in the datasheet. If you follow the same sequence it might not work (has not worked for me). Did you bit-bang SPI to program AT89S8252 or did you use another uC with inbuilt SPI? It would be great seeing my AT89s8252 programmer working atlest once :o). If its ok, can you please share a few info here? Regards, Raj Shetgar |
