Purchased K8048 kit some time ago. I only built it recently. I am confident that it has been built correctly. I have tested all the static voltages and tested the effect of changing the inputs manually at the D-Type connector. I get the same error what ever i do.
The error message is:
“NO PIC ON BOARD,
PROGRAMMER MUST BE SET TO PGM MODE,
PIC TYPE MISMATCHED WITH SOFTWARE”
Below are the test conditions.
Power Supply 18.5V Regulated(laptop PSU). Volatges measured on K8048 board are Vpp=13.3V, Vdd=5.02V.
PIC Programmer Version= Rev:2.6.0
I am trying to use the demof627.asm demonstartion program to test the build.
Test1
SW5=Standby, LD7=On,LD8=off,LD9=off
Click Write and i get the message above.
Test2
SW5=PROG LD7=On,LD8=off,LD9=flashes
Test3
SW5=PROG LD7=On,LD8=off,LD9=flashes
Click Write and the following happens
LD7=On,LD8=on,LD9=flashes
and the above error is displayed.
Test4
SW5=Standby LD7=0n,LD8=off,LD9=off
Press any of the SW1-SW4 switches and LD9 flashes.
I have read through all of the posts on the forum but cannot find anything that solves the problem.
Any help or suggestions would be greatly appreciated.

Hi, Test 1: LED’s OK. The error is reported beacuse the PIC can not be read and identified in the standby mode.
Test2: behaviour OK.
Test3: LED’s OK, error should not be reported. Possible reasons are:
The MCLR (pin 4), PGD (pin 13) or PGC (pin 12) connections to the programmer socket are not ok. This includes T1 and T2 and their surrounding components.
The wrong type of PIC is selected in the programmer. This type should match the type defined in the program source file that generated the hex file used for the programming.
?
Test4: The behaviour is normal (but somewhat illogical) for the K8048 (this is because the PIC gets its Vdd through the switch pressed and the PIC input pin.). See [url]K8048: PIC not fully made voltageless in "Sleep" m]. This behaviour is no part of the problem anyway.
Yes, I am having the same problem - the software can’t find the pic chip in the K8048 programming board, even when everything is set the way it is supposed to be. I have no way to check the chip (16F627) supplied with the programmer kit, but, I did install a 16F628A, configured the soft ware for that and the software could not find that one either. I think that there is some kind of incompatibility between the software driver and the com port or the comm port (1) which is known to be good is not correctly connected to the K8048 board, via the DB-9 female to DB-9 male (straight through) cable.
Also, I tried to access the board with Microchips’s MPlab software and it did not work either.
Also tried Prog9000 and it did not work either. So, I am at mu wits end. I think that there must be something I don’t understand. but, the documentation I have had access to is too incomplete and fragmented to know if that is so. My current experience with the K8048 is taxing 30 years of microprocessor programming experience to the max and I still am clueless! I guess I have a classic case of the computer blues!
