i need jdm usb circuit

[buntheun]

dear all please help me i need it so much na.....!!!

[mackrackit]

Why do you need this?

[skimask]

huh...
I type this into Google...
jdm programmer usb
and on the first hit, I get a standard jdm programmer circuit with a serial port at one end.
I type in usb converter, and I get lots of hits for a USB-serial converter...and get this...I also get hits for USB-serial adapter chips...like one from FTDI, a CP2102, a CP2103...
Amazing isn't it...!!!
That Google is one neato search engine ain't it?

Why do you need this?

cos my computer dont have com port so i need it

Refer to post #3...

The JDM, while easy to make is very iffy in the best of circumstances (with a proper serial port). With a USB-to-serial converter, it will NOT work.

If you insist on building your own programmer, google for PICKit2 clones.

If you work really fast, or your time is not to valuable, then build one.
Or save the headache and buy a PICKIT2 from microchip. Plugs into the USB port.

i realy want buy it but my country dont have the market that sell all of that ....that why i try to fine the circuit for build it myseft and it can improve to know my about it ...
thank!!!

i live in Cambodia!!!

sounds like a fairly weak excuse to me. A quick Google search tells me that there's more than one country out there that'll ship to Cambodia...

Then how do you plan on ordering the pieces/parts to build said PICKIT2 clone?

Money orders or cashiers checks are also handy...

[buntheun]

please help me...how i do?
thanks!!!

I need it too...a want a simple USB programmer for my laptop like JDM to program few pic..84/628 and serial eeproms...

i don't need complicated programmer like pickit or junebug since it seems overkill to used the above programmer to program 3 to 5 pic/eeprom in 3 months...

Take a look at the PICKIT2 from Microchip anyways...
$35USD, programmer, logic analyzer, serial communications windows, well supported, no headaches, and is saving the extra $10-$20 really worth the pain?

Hey guys, I'm new to this forum but would like to share my thoughts and experiences and this subject as well...

I followed the posted link to Microchip's "PICkit2", and if my computer hadn't been giving me trouble last night, I would have bought it right then. I would seriously consider paying $35USD for the "PICkit2" before trying to gather parts and components to build an iffy clone-type programmer that may not even program the PICs you're using or going to be working with. The best feature of the PICkit2 is the ability to load a hex file into the PICkit2 itself, and program MCU's in the field (with an appropiate USB power supply), without the need for a PC! I really wish I would've looked more into what Microchip Technologies offered before buying the programmers I have now...
