hello majoka sir,
i m confused with first one & PIC-and-EEPROM-Programmer pcb layout . i hv made pcb of (which was in pcb folder ).i made 2 times bcs first time yr pcb layout was not fit for 40 pin controller. at last....
(1)what is d purpose of second one.
(2) is the programmer got supply from pc? there is no external supply.
(3)what is d meaning of JDM & RCD programmer.
plz remove my confusion . i m little bit far to complete.
thanku very much!

hi yashshailesh
i make it and i am using that

(1)what is d purpose of second one.


i use female header that normally used with lcd
or u can use bases of round holes that r in goodquality
purpose was because every pic ic has its own pin configuration
so 40 pin has outer boundary header and small ic uses inner boundaries header
connections r also different for different rows

(2) is the programmer got supply from pc? there is no external supply.


yes it sucks power from serial port of pc may not work with lap top that has less power port and usb to serial converter can not be used here

(3)what is d meaning of JDM & RCD programmer.


these r named of programmers
see this
http://feng3.cool.ne.jp/en/rcd.html
header or ic base should be as

sir thanks 4 repply ,
sir i hv made programmer and when i m burning through ic prog ther is no indication on programmer ckt (led is not glowing).
plz help sir,

one thing more , d icprog messaging every thing (erase device, sucessfully varified,etc) without connecting programmer board. i think prog not getting acknoledge from progm board. sir plz see my pcb layout.

hi yashshailesh
ru make it on pcb board or varoboard
even if not connected it should show verified successfully
ru set the com port no in setting
many software can be used with this check with other
picpgm programmer software
winpic prog
winpic etc
this hardware supported by these software and check hardware once more

hello majoka sir,
i hv used winpic800 it still not getting acoknowledge . a made hardware.
sir i have no camera otherwise i can send image of hardware. sir i hv checked hardware connection ,there is no error.
sir can u tell me process- from conecting it pc port to running program with either prog r win800.

Dec 4 2010, 12:39 PM
, i made programmer as majoka send me doc.i hve used first pcb . i hv send dis in earlier post n then made hardware . sir problem is dat, when i m connecting programmer wd pc n starting ic prog there is no indication on progammer.

Hi Yash,

Majoka has posted 2-3 circuits of programmer. which one you've built? and what programmer software are you using for them?

also the olimex programmer circuit is simplest


you can make a six pin header and connect device to it. check olimex website for frontend software too.

hello sir sorry for late ,
i use pcb which is in pcb folder .i hv attached in earlier post. i made hardware . sir i hv used icprog1v06. when i m burning program there is no indication (acknowledgement). plz sir help me wt i m ding wrong. i m waiting yr response.

hi yashshailesh
i make it also on pcb and it work in first attempt
check ur connections once again
specially check transistors
all detail is given here
http://feng3.cool.ne.jp/en/pg5v2.html
in documentation 2 things are clearly mentions


1) I recommend checking to see if there is enough output voltage at the serial port your personal computer. If TxD, DTR, and RTS do not have more than +7.5V(or -7.5V), this programmer will not work well, especially, with the latest laptop computers that using low power RS232 interface ICs.

2) The GND line of a serial port forms relative VDD on a PIC programmer. All the GND symbols in a circuit diagram are a PIC programmer's GND. Never connect them with GND line of a serial port.


other important points r also available on above link

hello sir ,
i want to ask,
(1) i hv 2 type of crystal 12MHz & 24MHz. i m using Pic 16f877a. which one is suitable .
(2). what will be capacitor combination with that.
