#Mplab icd 3 usb driver software#
So I use the Microchip software to program the microcontroller. When it comes to programming the microcontroller, ICD3 is not even in the list in the CCS C Compiler GUI. Is ICD3 even supported by CCS C Compiler? Note that I am able to program my microcontroller via the Microchip "Integrated programming environment" but not via CCS C Compiler. The problem is that the CCS C Compiler is neither able to program the PIC18F Microcontroller via ICD3 nor does it execute the debug function. I used this compiler before at the university as well. I have recently bought ICD3 since I think that being able to debug a microcontroller program requires that we be able to see what is happening inside it. Refer to Section 24.0 “Electrical Characteristics” for additionalįix up your decoupling and let us know what happens.
The VCAP pin must not be connected to VDD, and must have a capacitor between 4.7 μF and 10 μF, 16V connected to ground. You can see that for every \$V_\$ (which is very bad.) Per page 20 of the datasheet:Ī low-ESR (< 5 Ohms) capacitor is required on the VCAP pin, which is used to stabilize the voltage regulator output voltage.
Your _MCLR resistor and use of ICSP port 1 should pose no issue with the debugger.ĭo you have sufficient decoupling, per the PIC24 datasheet? Decoupling capacitors must be installed as physically close to the PIC24 as the layout and pinouts permit: I'll trust that your 3V3 rail 'works' for now. Either a bad device, bad connections on the ICSP or power issues. Edited per the updated information provided.Ġx0 generally means no communication.
