I've never had any problems like that before. The only EEPROM write problem I have had, is in a 16F876 running at 20MHz. Sometimes the write fails. I haven't been able to nail why, but dropping to 16MHz cures the problem. -- Best regards Tony mICros http://www.bubblesoftonline.com mailto:sales@bubblesoftonline.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
