#158443 - why do you think it IS the code? Responding to: ???'s previous message |
Also, as I have already said, try to separate the problems: write the EEPROM in known good programmer or hardware and try to read it out using the '51; and then the other way round. This might shed some light on where lies the problem.
Also, separate possible compiler problems: try to write/read 4 *bytes* at a time (e.g. an array of 4 bytes, or simply, 4 separate bytes), rather than float. If you succeed in this, you can then proceed to the float. JW PS. You said a single byte works - is it on this very hardware? Post the related code. |

You are right Henry. It should be 'bit'. | 01/01/70 00:00 | |
