Hi everybody,

I think I have burned the dsPIC33FJ.. on my Full-Flex board when I was trying to acquire same analog signals from a potentiometer (I am not a beginner in Electronics, but this thinks happens if you start to interface the device with something)..



I am no sure about it because seems (due to the led _b_link__ing) that my application inside the micro-processor is still running.

The problem is that I can not program anymore the board, MPLAB ICD2 application tell me that the target device (dsPIC33FJ) is wrong:

Running ICD Self Test
...Passed
MPLAB ICD 2 Ready
Connecting to MPLAB ICD 2
...Connected
Setting Vdd source to target
ICDWarn0020: Invalid target device id (expected=0xBF, read=0x0)
...Reading ICD Product ID

My question is, because I have some maschines to soldering SMT components, can I just buy a new chip and change the one on the board?

On the DSC microcontroller there is installed a special operative system when I buy the (FLEX) board?

Thank you in advance for opinions.

Ciao.
