You can only program a pic via serial if you load a bootloader....
To program a pic you need to use PGC, PGD, MCLR Vdd and Vss.... Via a pickit2/3 or home made hardware.... Using software to suit the design..
The MCLR is HVP ( high voltage programming pin) this is the one that needs 12.5v+ whilst programming... Look at the circuit I showed you.
The other option is to use Nigel's hardware ( in my tutorial ). I don't think Nigel's maintains the software anymore but I'm pretty sure it does the pic16f877a
in nigel's P16Pro40 what kind of connector that he use? Sub-D 9 pin or USB type A?
for the link that u give i cant find that transistor model number in my country BC557, IC that look like comparator( i do not know the model ), 74LS06 and 4013 cant find either...
what i prefer is 1 usb to power the PIC and can also program... i make RS232 programmer board because i thought it the basic but it harder than what i think...
Or you make the other one, on the same site, the USB one .... Its a pickit 2 clone.... But!! you'll need someone to forward you a chip with the pickit2 software on it
at my lab i can program my PIC... how to program it with the pickit2 software in it so i can use on my laptop... beside software what i need more? bootloader? firmware? how to get it and how to implement into the chip?
I built a relatively cheap pickit2 clone... It cost me less than a tenner.... pickit2's are the best way to go...
Have you used MPLAB? With MPLAB and pickit2 or 3 you can program all pics.... I have a 40 pin programming socket and two 28 pin sockets... With these I can program most chips

MPLAB is not a language. It's a development environment. You can write mikroC in MPLAB. MPLAB actually makes the programming of the chip much, MUCH simpler.

MikroC Pro For PIC is a software of debugger i think...
back to my main question...
The training kit got 40 pin ZIF socket, if i want to program it on the Training Kit without use the ZIF socket(i think this is it name), which pin that i need to connect to the socket... what i done before i connect one ground pin(12), MCLR pin(1), RB07(40) and RB06 pin(39), both VCC pin(11,32) = PIC16F877A... result is error 10.47v... sometime i got different PIC detected... did my connection miss/misconnect?
ya it use USB type B that commonly use for printer in this year... for power supply it has dedicated power supply i guess... use 230V to smaller(i dun know)...
