> I'll rerun the test cases when I get back to my office this afternoon > and report the new times. Here are the newly measured programming speeds for 16F630 after fixing the programming times for program memory and EEPROM. Times are in seconds. 1 Verify 2 Verify ------------- ------------- Empty Full Empty Full USBProg (USB) 2.0 5.3 2.6 5.9 USBProg (ser) 1.6 4.8 2.2 5.4 ProProg 4.6 8.3 6.7 10.4 EasyProg 2.7 6.3 4.5 8.0 I have the default not set to 1 verify pass for the 16F630 and 16F676. Even so note that you're only saving 600mS by skipping the second verify and the associated voltage switching with a USBProg. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
