Hey guys, I finally got around to programming a PIC again, and need some help. I was wondering if anyone had an Inchworm Plus could verify their VPP voltage for me. In MPLAB it tells me the ICD 2's VPP is ~12V, while at the PIC I am measuring -4V, sometimes 7V, once it was 5V...sigh.. I am thinking my programmer is damaged (or wrong setting) and was wondering if someone has seen this before. Unfortunately I need to get this PIC programmed by Sat, as it is going into a motorcycle light controller for a parade this weekend!
Here are the errors I get:
Connecting to MPLAB ICD 2
...Connected
Setting Vdd source to MPLAB ICD 2
Target Device PIC12F683 found, revision = Rev 0x3
...Reading ICD Product ID
Running ICD Self Test
...Passed
MPLAB ICD 2 Ready
Erasing Target Device...
ICD0152: Failed to read all of requested bytes (0x0 of 0x8)
...Erase Failed
ICD0152: Failed to read all of requested bytes (0x0 of 0x2)
ICD0082: Failed MPLAB ICD 2 operation
It also seems to read just fine. Is it safe to simply use my power supply to get 12V to VPP and bypass the Inchworm?
COM1 settings: FIFO, bps = 57600, data bits = 8, no parity, 1 stop bit, no flow control.
Thanks so much for any help!
