This documentation written April 17, 2004.

Kit 149D has added the 10K resistor needed to program

the 16F88 PIC chip supported with diypack22.zip (R25).

It also has the 3 protection resistors, uses a USB ‘B’

connector and adds a sixth pin to the header and harness

for ICSP programming added earlier.

Parallel ports are slowly disappearing from PC’s and

laptops which means that our current PIC programmers

are all facing extinction. So this is our first PIC

programmer using the USB port. It can also accept input

from a serial port at the flick of a switch. Note the PCB

has a presoldered surface-mount IC on the top of the

PCB. This is a FT232BM chip and details about what it

does can be found at

Software

Download the User Interface for the firmware from

http://www.crowcroft.net/kitsrus/diypack22.zip

Run setup.exe. The program will unpack in

C:\diypgmrp. Make a desktop icon for MicroPro.exe.

This is the User Interface software to run with K149. (It is

also used for our other PIC Programmers: Kits 128, 149A

& B, and 150.) MicroPro.exe will auto detect the Kit

149C so long as the correct COM port is selected. Pre-

programmed firmware is supplied with the kit in the

PIC16F628 IC. This firmware will only run with

MicroPro.exe from diypack22.zip. If you are upgrading

earlier diypackxx’s reprogram the firmware with the

supplied diyk149bc.hex file in diypack22.zip.

NOTE: if you log onto this site and find later versions of

diypack.zip then make sure you still download

diypack22.zip and not the latest version. After you have

KIT 149 (version D/E) USB PIC PROGRAMMER

http://www.ftdichip.com/

the kit working then you can download the latest version,

upgrade the firmware & run with the latest MicroPro.exe.

Assembly

Look for k149bc.pdf in C:\diypgmrp. Solder the lowest

height components first: the resistors, diodes and IC

sockets. Do not put in any of the ICs. (Note component

designators C2 & C3 were omitted.)

Make sure you do the 5V check at the TEST points in the

lower right-hand side of the board before putting in the

ICs. Make sure the ICs are around the correct way. (The

notch on the firmware and the 74LS06 ICs are in the 6

o’clock position.)

16V-18VDC is needed to power the programmer. Since

the FT232 draws about 50mA this means that the 7805

will get a little warm. Note that the FT232BM will turn

off when it is not in use to save power.

USB drivers. These can be downloaded from my

website. The PIC programmers communicate with the

FTDI device (FT232 IC) using a Virtual Com Port

device driver (software). This driver NEEDS to be loaded

onto your PC before you can use the programmers.

Currently, (April 17, 2005), the latest Windows XP USB

driver (unMicrosoft Certified) is r9052154.zip (October

2004.) The latest Microsoft Certified driver (July, 2002) is

p8002104.zip. Use either one.

Power. When you connect power the Power LED will

light up. Plug in a USB or serial cable. Select the DPDT

switch accordingly. Then start the program. Make sure the

correct COM port is selected. Note that if you switch

between USB & serial modes you will have to reset the

COM port. Exit the program to reselect the COM port. If

you forget which USB com port is installed you can

always look it up at Start>Settings>Control

Panel>System>Device Manager >Ports

to a folder C:\diyprgmp\USB then did

Start/Settings/Control Panel/Add Hardware.

programming then use the 3 x 20 pin IC sockets

provided. Break one of the sockets to make pins

21-40 of the 0.6” wide socket as shown in the

photo on p4 of the k149a.pdf docs. However, if

you program a lot then please buy a wide-slot 3M

ZIF socket as shown in the photo to the left. We

sell them at $US10 plus $US3 postage. You can

order it direct from me at

Or buy the socket from one of my distributors. If

you use an Aries ZIF socket with smaller pins

then do not feed to much solder into the pin/pads

when soldering. You will just short-circuit to an

adjacent pad with excess solder.

In my PC I just extracted the driver (either one)
