#100131 - Am I missing something ? Responding to: ???'s previous message |
Richard Wiglinski said: i don't have EPROM. just the EEPROM (the same as in the source list of the circuit above.) I don't SEE an EEPROM, just RAM in the circuit ? the problem with the VCC is the following. i don't have a exact 5V Vcc at home. I bet you have 10 5V sources at home ! Take one of the wall-wart power supplies for your printer or an old fax machine or something - look for one that give 9V < Vout < 12V. Get an LM7805 regulator and attach that to the PSU. Are you using NVRAM instead perhaps ? Steve |
