I am using Multi PIC JDM programmer version 5.2 and PICprog4u for programming my PIC 16F628A. I had been using this for quite some time and it had been working alright. Now suddenly a problem has cropped up. Now when I open PICprog4u and select JDM programmer it is telling the message “Couldn’t open COM port” and after cliking OK from some 6 to 7 times it was detecting the programmer with the message “JDM programmer was found on COM1”. There after the programmer works alright. Picprog4U version I am using is 0.8.2
When I checked up the hardware tab of the PICprog4u programming window COM ports 1, 3,4,5,6,7,8,9 were ticked.
On checking up the COM ports of my PC from the device manager window, I found that the same ports were present and additionally COM ports 10,11,12,13 were also present. I disabled the COM ports 3,4,5,6,7,8,9 and tried programming and now my programmer works alright. Now in the first instance itself I get the “JDM programmer was found on COM1” message.
Can somebody help me to understand this:
- Why only on disabling COM 3,4,5,6,7,8,9 my programmer worked alright whereas there were 4 more ports (10,11,12,13) present on my computer.
- How this problem didn’t occur initially and has suddenly started coming.
Also I have observed that in my PC ports only COM1 is Communications Port all others are listed as blue tooth serial port (3,4,5,6,7,8,9,10,11,12,13)…
Can anybody help me out!!!!!
Thanku friends
