Guest Carel Posted May 3, 2003 Report Posted May 3, 2003 Hi all,I’ve a problem with the jdm programmer, the voltage between Vss and MCLR# seems to be on the low side. After I received my pcb from mike I started stuffing the jdm-board. After playing with that multimeterthingy I found these value’s. “Click on "Enable MCLR", measure voltage between Vss (Pin 12/31) and MCLR# (Pin 1) : ca. 14 Vâ€Reading: 12,60“Click on "Enable Vcc", measure voltage between Vss (Pin 12/31) and Vdd (Pin 11/32): ca. 5 V “Reading: 4,73“Click on "Enable clock", measure voltage between Vss (Pin 12/31) and RB6 (Pin 39): ca. 5 V +/- 1 V“Reading :5,52“Click on "Enable Data Out", measure voltage between Vss (Pin 12/31) and RB7 (Pin 40): ca 5 V +/- 0.5 V “Reading: 4,24Al the voltages seem to be stable, so there is no leak or something. Does anyone know what is wrong? Thnx , Quote
LO Posted May 4, 2003 Report Posted May 4, 2003 just try burning the PIC?my voltages are similar and Ive burnt 10+ PICs now, but maybe I was just lucky?LO Quote
Guest Carel Posted May 4, 2003 Report Posted May 4, 2003 Ok, it’s definitely worth a try! I have had sleepless nights because of this problem, couldn’t find a thing wrong. ??? Quote
d2k Posted May 4, 2003 Report Posted May 4, 2003 yes, my test voltages for the JDM were slighty off too and it's burnt pics fine - just follow the instructions to the T! and u should be good...BestDan Quote
