Hi all
I recently bought an assembled Inchworm programmer. I connected it to my computer via COM1 port and tried to connect to MPLAB 7.5.
Here's what I did after connecting the programmer physically
In Windows Device manager
1) Set it to COM1
2) Changed Byte per second to 19200
3) Row control=Hardware
4) Turned off FIFO buffer
In MPLAB
1) Programmer -> Select programmer -> MPLAB 1cd2
2) Programmer -> MPLAB ICD2 Setup Wizard
In the wizard:
i) Set it to COM1 and Baud rate to 19200
ii) Select "Target has own power supply"
iii) Check "MPLAB IDE automatically connects to the MPLAB ICD 2"
iv) Check "MPLAB ICD 2 automatically downloads the required OS"
When the wizard is finished this warning is displayed:
"ICDWarn0034: Please ensure that your system's serial FIFO buffers are disabled."
3) Programmer -> Connect
Output: Displayed the following warning:
"Connecting to MPLAB ICD 2
ICD0021: Unable to connect with MPLAB ICD 2
MPLAB ICD 2 Ready"
4) Programmer -> Download ICD 2 OS -> Select (ICD01020701.hex)
Output:
"Downloading Operating System
ICD0021: Unable to connect with MPLAB ICD 2
...Download Operating System Failed
ICD0286: Unable to communicate with ICD
ICD0286: Unable to communicate with ICD
ICD0286: Unable to communicate with ICD
ICD0286: Unable to communicate with ICD
ICD0286: Unable to communicate with ICD
MPLAB ICD 2 Ready
"
I am sure that there is nothing wrong with both programmer and serial cable connection.
Because..
I) I hocked up my oscilloscope to the COM1 pins and used some other program to see the program's out put on the oscilloscope properly.
II) The programmer was checked by some other guy and he told me it was working fine.
III) Oscilloscope didn't show any signal when MPLAB trying to connect.
I need help badly. I am pretty sure someone here can definitely help me.
