>> My suggestion is to program 5 times in a row to insure data integrity (while monitoring the temp with a finger to protect against cooking the device), until they come up with a patch for the programming software. << This probably won't work at all on PICs. First, the flash parts have a self-timed write. All the programmer has to do is wait the maximum time the write could take. Second it is unlikely that a programmer will surface to the user interface the ability to re-write the data without first erasing the part. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
