Did I just fried my PIC?
How easily is it to destroy a PIC18F?
Look at the schematics below. When soldering the components, I accidentally did some mistakes.
I solder the capacitor connected to the 78L12 with its polarity reversed.
I solder the BC556's Emitter and Collector in reverse.
I accidentally swapped the Pin 7 and 8 of the DB9 connector.
Before I fix all the mistakes, I tried WinPic and it says the data voltage is too high(which i assumed is PGD).
I tested the computer serial port and the cable as well by shorting Pin 4 and 8. WinPic then said programmer has been initialized. I tried to toggle the Vpp, Clock and Data checkbox. Toggle Data, I get 1. Toggle Vpp and Clock, I get 0.
After fixing all the mistakes, I tried again and the same data voltage too high error is still thr. I measured the MCLR voltage and it is 14.2V. Is this too high?
The Vdd id around 5V. I don't know what else to check and I don't want to test it with my other PIC chip fearing that it might be destroyed.
