#105931 - I did test it Responding to: ???'s previous message |
I tested it with the actual device and i got the error "Error. Device did not acknowledge the PROGRAM ENABLE instruction."
I then tried programming the chip using my parallel programmer i was able to program it, so the controller was programable. I used the parameters ats5xisp -BEPV -D52 -H test.hex but without no sucess, tomorrow i will check the actual waveforms. but the thing is when i am able to use the circuit as a simple RS232 convertor for the TX and RX lines what could be worng with the hardware. I was able to recieve and transmitt upto 57600 bps. I looped the RX in to the TX out and was able to use the circuit without any problem. The readme file says it has not been tested with the S51 and S52 devices, is the programmer capable of working with the s51/52? |

Doesn't work | 01/01/70 00:00 | |
it works only for the AT89S8252 | 01/01/70 00:00 | |
Are you certain it's a software problem? | 01/01/70 00:00 | |
i have tested the hardware | 01/01/70 00:00 | |

Only TX? There are 3 more to test. | 01/01/70 00:00 | |
