Guest Sam6 Posted August 12, 2003 Report Share Posted August 12, 2003 I've built the sid device , but I found when tying to run the voltage regulator on the core module ???got very hot and the device wouldn't run. I checked the circuit and finally found that the Pic had a dead short between the + & -the Vdd and the Vss (out of the socket) is this a dud chip or have I programed it wrong? How dose one test the chip to see if its a good one? I've built my own Pic programmer. any help and I'll be most pleasedthanks Quote Link to comment Share on other sites More sharing options...
Steven_C Posted August 21, 2003 Report Share Posted August 21, 2003 Yes, it appears as if it is faulty, I just checked one of my chips, and it is not a short between pins 11, 12. Quote Link to comment Share on other sites More sharing options...
pilo Posted August 21, 2003 Report Share Posted August 21, 2003 are you sure it's on the 18f452??? not on the pcb?? remove the 18f and test the pcb too be sure!It's strange if the pic has a short on VSS and VDD... Quote Link to comment Share on other sites More sharing options...
