Which Pin only used to program the PIC

[Ragens]

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...

 

[Ian Rogers]

He uses this one..

 

[Ragens]

owh my... that one extinct already...

 

[Ian Rogers]

It will still work with your pic16f877a...

okay... how to convert it to the connector that usable at my laptop?

 

[Ian Rogers]

You buy a cable **broken link removed** about £7

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

 

[Ragens]

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?

 

[Ian Rogers]

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

i still not use MPLAB yet... i need learn MikroC Pro For PIC first... because MPLAB more complicated...

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.

 

[Ian Rogers]

I think mikroC IDE is more complicated than MPLAB IDE... Just me... but then I've been using it for years..

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?

 

[Ian Rogers]

Which board have you got? Are you using the ICD from MikroE?

 

[Ragens]

it not international board... it just custom made from a company that supply few component in my country... but ya... they use ICD from MikroE...

 

[Ian Rogers]

I still like to see a close up picture or something

 

[Ragens]

It called Micro Controller Embedded System...

 

[Ian Rogers]

Cool piece of gear.... Where does the PC connect for programming? Is it USB?

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)...

To get a "MCLR is low voltage" error means you have too much loading on the MCLR pin. Do you have a pullup resistor from MCLR to Vdd?

u mean need to put 47K ohm from pin MCLR to both VDD?
