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 have used a 16F628A instead of 16F628.
Can some body help me about this problem. Is there an thing missing in (...)

hi all,
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?
thanks

has anyone successfully used a P16PRO to program a PIC 16f877a ???
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.

I would say to start with the newer devices, like 18F252. The 16F84 is quite old and although learning it will still teach you the basics, the 18F parts work differently. Why not learn on something more modern that is more likely to be used in new designs?

Hi,
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.
MPLAB would be connect to the ICD2 modu

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.

More I/O means ,easy programming (in a way!!!)
Purchase or construct (Only depends on time available and budget) a programmer with ICSP support So that each code change can be easily tested in target..
Start doing as in 8051..

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
