icd2 mc34063a
I have built ICD2 from **broken link removed**
Now MPLAB can connect to it and Vdd voltage is right, but Vpp voltage is ~8V.
When I measure at the mc34063 dip ic, my voltmeter tells me there are only ~8V on the output where it normally must have 13V.
The second thing is: The first time I connected ICD2 to voltage, the DG411DY IC got very very hot and finally smoked away.
I found out that PIN 10 and 11 put 13V and GND over an internal MOSFET together. But only when PIC16F877 output RC2 is low. Now I have bend the 2 pins up.
DOES ANYONE KNOW WHAT IS WRONG IN MY ICD2 CLONE from MCU.CZ????
Thanks
