I have made a K149A programmer, it programmes the 16f84a very well but donot programme the 16f877a .I have checked the hardware many times through out but there remains some problem it donot even detect the 16f877a .

i want to connect 4 7-segment display to PIC 16f877a
the 1st is 4 digit
the 2nd is 3 digit
the 3rd is 3 digits
the 4th is 2 digits
and i want to use the minimum number of ports beacause i need it to connect sensors and the PWM port to motor
so i tray to do that with one PIC
is it could>? and how?

if so please post how you did this.
i can not get it to work.. it programs perfectly when compiled for a 16F84. then i re-compile for 16f877a and change the picall software (regged version) to 16f877a and it don't work.

You must program the ?c on the ICD2 module with the correct bootloader. You can use bootloader from Zaphod42 if you use 16f877a. Connect your ICD2 module to the serial port with no-crossing cable and your target board to ICD2 module. POwer the boards. Run MPLAB and select in debugger menu the ICD2 tool.

First, maybe your programmer can program only 16F84 not 16f84a. For example, programming methods are diffrent between 16f877 and 16f877a.
Second, I used to use JDM programmer with ICProg. For ICProg, I had to run a reg file for winXP. If you are using WinXP or NT system, you should do that. You can find this reg file from ICProg web site.

VoltageDrop, you could uncheck 'blockade configuration' and use the test feature to check your JDM (Vdd, Vpp in programming mode). PIC16f877a has a little lower Vpp threshold than that of PIC18F4550, so your JDM may not work with 18F4550 while it works with 16f877a. JDM configuration of WinPic800 is exactly for this Olimex PG2C, you don't need to c
