Very Simple ICSP Programmer

[NavMicroSystems]

The chip CAN be programmed without any programmer ,eg. JDM etc, just the right serial to chip connections and IC-Prog right?

You need to make sure the voltage levels on all pins used for programming are within the specs.
This is actually all the JDM-programmer does.

AGAIN:

have you checked the levels on your COM-port yet?
have you read all specs?
Have you understood the concept of JDM?
are you sure your PIC is ok?
(you might have killed it with your experiments)

As long as you haven't understood what you are doing you will never get this working.

The time we all have spent on this thread is worth far more than the $9,95 a working programmer would have cost.

Why don't you just go and get one?

[JoeCJK]

The serial port voltage levels are about 5V.(notebook)

And you're probable right, I should just go and get a programmer, althought it will cost some time and a bundle in shipping fees. Will try with a smaller value resister and other stuff just one more time.

Thks.

[NavMicroSystems]

Joe,

the PIC-PG2 is a JDM-type of programmer and will (most likely) NOT work on a 5V COM-Port !!

If you had told us you are working with a 5V COM-port,
we would have told you that the method you are trying is not going to work.

You must tie RB4 on the F628 to GND (or at least pull it low)
and you must apply high voltage (~13V) to the Vpp pin to make it work.

The links posted on this thread would have given this answer.

[JoeCJK]

Thanks Nav,

I tried it on a desktop and it works. But I think we are talking about different programming modes. Here is my rundown: (16F62X series)


Low Voltage Programming : MCLR is low(+ 5V) , MCLR is shorted to RB4 as
RB4 needs to rise to 5V also.

High Voltage Programming : MCLR is high(~ + 13V),
RB 4 has to be grounded



Voltages to Vdd of both modes are +5V. High voltage programming is better than low voltage programming in that all I/O pins can be used. (RB4 can't be used for LVP) But the downside is that it is harder to get 12 V source.

Yes, buy one before you blow up the serial port of your computer!

I am not able to Program any PIC using the Simple Interface suggested. I am using Windows XP (SP2).

I get Programming failed at Dataaddress 000000h. Any help or suggestion. I am using ICP, Windows API , I/O delay 1. I tried changing these setting to diffrent settings but could not get the Chip to Prog. I am trying to Prog F72, F873A and F876

[charudatt]

I just found out a good explaination to the possible problem I could be facing with my programing software.

Just thought of sharing the link with the Thread.

http://www.talkingelectronics.com.au...-03-Using.html

I shall post my findings later when I overcome my problem.

regards

[Art]

I have just set up a 16F877 circuit for ICSP using this interface
with my desktop PC. (XP service pack 2 BTW). No problem with
read, verify, or erase

I used the settings with IC prog suggested earlier in the thread:
I/O delay 20, JDM programmer, Direct I/O with nothing inverted.
Have you have also powered the pic seperately with 5 volts while trying
to use this interface?

Cheers, Art.

Hi Art,
Please, could you tell me what are the connections that you have made between the Serial port and the PIC16F877 ?.

PIC Serial Port
MCLR/Vpp ---- ?
RB3/PGM ---- ?
RB6/PGC ---- ?
RB7/PGD ---- ?

Thanks a lot !.

[amane]

I've been using WinPic800 to program PIC18LF4620 using my PC's serial port. It's working fine. I used JDM programmer as the hardware settings. I connected the PC to the programmer using DB9 to ICSP cable. I'm thinking of getting myself a development board with PIC18LF4620. The board comes with ICSP connector that uses PGC, PGD, /MCLR, 3.3Vdc and GND to connect to the PIC and program it. I'm wondering whether will I be able to use the JDM programmer settings using a DB9 to ICSP cable to program the board. The board is going to cost me a huge sum of money and I wanted to be sure that I have the necessary tools to program it. Thanks!

Hi Charudatt,
1. please check whether the programmer has external 13.5 volts for Vpp if the derived voltage from COM port is used, pl ensure its value by measurement.

2. Please try winpic800 programme and see. www.winpic800.com

That 1st post was over 1 1/2 years ago... Ya think he might have it figured out by now or had moved onto a different project... I'd doubt if he's sitting in front of his monitor staring into it waiting for another answer

Hi Skimask, you are right-- i too noticed it jsut after posting-- however, even if it is useful to anybody else, it serves-- coming to using winpic800 (ver3.60)programm, the hardware under concern is to be treated similar to propic 2 while configuring the hardware under winpic800 - this what the orginal hardware designer suggested.

i agree and this helps only to locate winpic800 drivers, which are really good.

[Squibcakes]

Bearpawz,

Show us your basic blink code and maybe we can figure it out. BTW did you use a dropping resistor on that LED? If not you may have blow up your IC. Don't suppose the polarity is around the wrong way?

Oh yeah, Winpic800 is a much quicker at programming than IC prog.. I suggest using that now days.

DTR/CTS lines connected to the data I/O are for Program reading and writing of the chip.

Cheers and....


Happy New Year to All

[bearpawz]

Ok, I don't know what Im missing here....

I used the circuit after reading through this thread... actualy seems to be no problems with programming. Im using IC-PROG, load a simple hex file made from the pbp samples code to blink an LED on port 1. Im not using any external oscilators.

When I program, no problems. Read back it verifies correctly. Just to be sure I shut the whole thing down, restarted IC-PROG, and reloaded from the pic and there is indeed code in there.

When I pull pic out of the circuit and try to plug into simmple LED blink circuit, nothing happens. Blink circuit is nothing more than 5V+ on VDD, GND on VSS, Cathode of LED to ground, and Anode of LED to Pin 6 (RB0)..

Im using PIC16F818... Am I missing a config fues some where? its been over two years since ive toyed with these things so I cant remember what my set ups were back then

thanks in advance


oh yeah, and I already bought the programmer off e-bay... just waiting for it to show up from Hong kong... mean while this is all ive got and i have to start getting work on this project going.

MCLR pulled up to +5?

[bearpawz]

Actually, its not programming as nice as I thought. Not it seems hit or miss as to weather or not it fails. This is the scheme I have:


+12V------- LM7805 -------+5V------O |-- ->VDD(14)
| (switch)
|
GND/Vss




RS232 PIC16F818
TXD (3) ------[4.7] -------- VPP (4)
GND (5) -------------------- VSS (5)
DTR (4) ------[4.7]--------- PGD (13)
CTS (8) -------------------- PGD (13)
RTS (7) ------[4.7]--------- CLK (12)



ICPROG SETTINGS:
JDM Programmer on COM2, I/o Delay = 20, Direct I/O

I created a small program to blink an LED: Progam with these settings:

Oscilator = INTrc
Code Protect = OFF
Write Enable = OFF
Fuses:
WDT = 1
PWRT = 1
MCLR = 0
BODEN = 1
LVP = 0
CPD = 0
DEBUGGER = 0
CCPMX = 1


All in all just a head ache of problems... I sure hope my JDM programmer I bought of ebay comes in tomorrow... been over a week for "Air mail" to show up...

[Steffen44]

Hallo@all

I need help to connect my 16F877 PIC with the Resistors/Serial Port.
I does not work with the 5 Volt Power Supply.

what i have for 16F877 is :

TXD (3) ------[4.7k]-------VPP/MCLR

GND (5) -----------------VSS (GND)

DTR (4) -------[4.7k]----RB7/PGD (DATA ???)

CTS (8) -----------------RB3/PGM (DATA ???)

RTS (7) -------[4.7k]----RB6/PGC/CLK

are the Connetions wrong ? I dont know ?
IC Prog tells me the Error Code on 0000h.



What stands the two data lines for ?!
DTR (4) -------[4.7k]------DATA (????)
CTS (8) ------------------DATA (????)


Regards
Steffen

I've tested this very simple programmer with a PIC16F88 and it worked fine. Just programmed a PIC18F2550 as well and it seems to work (I programmed it and then read back the code, tried verifying etc and it worked). If it doesn't work, I'll post a follow-up post later on

The software I used was WINPIC800 version 3.55b, and I just chose JDM.

For once off stuff, this is wonderful. Thanks for the great programmer!

It does look like hardware issues. How are you connecting the JDM programmer.

1) - USB to RS232 converters can be problematical and don't always work.
2) - Serial ports on laptops (mainly older generations) tend not to be able to generate the voltages required to get the PIC into programming mode

Are you selecting the correct chip in the Winpic options ?
Have you tried Winpic800 (I'll let you google that one) or a different programmer that has support for JDM hardware.

[togum2000]

Hello Malcolm


I already tested all of the programs of Pic (Winpic, winpic800, wxpic, icprog,.... ) and all with the same problem, My Motherboard is a MSI KM4M-V ( VIA KM400+8237 Chipset ) the Processor is an AMD DURON 1.1Ghz. As to select the correct options of the chip, this everything correct. I hope somebody can help myself with the solution of the problem

[Gusse]

How much voltage you will have on MCLR/VPP pin when you enable Vpp (+13V) from Interface Test (Interface sheet)?
With JDM and standalone PIC I have 10.4V and with ICSP (PIC on applicatio board) 9.3V and it is still working. Sometimes ICSP needs more flashing trials to avoid errors. I think it is because of lower VPP voltage..., but not sure.
When it says "Initialising PIC-Programmer: Success." is should have all setting correct.

BR,
