Click
[File] -> Port
or double click the
COM x
label on screen to bring up
the COM port window. Select the COM port that you will use for serial
communications, then [
OK
].
Re-check the power and PC connections and turn on the programmer board.
You should see
Board connected
appear on screen. If not, check your cable,
the PC port setting and also that the switch is set properly.
If all is well, then as a simple system test, select
16F84
from the chip select
menu and click on
Read
. You should see some LEDs light and the programmer
will read from a non existant chip. The screen will most likely fill with
0000
's.
Now you can turn off the PCB and prepare it for the USB test.
First off, disconnect the serial cable and move all of the switch to the [USB] side.
To enable USB capability for your PC and this project you will need to install a
special driver. This is a piece of software that handles the communications
between the PC and the special USB chip on the programmer PCB.
Create a USB driver sub directory into the directory where your programmer
software was installed.
C:\diyk149
was the default. Therefore you would have
a new directory called
C:\diyk149\usb
.
The drivers come in 2 flavours, plug and play support and no plug and play
support. As this programmer does not have plug and play support, that narrows it
down to 1 choice.
You will need to visit this web page and download this driver.
VCP drivers for Win 98/2000/ME/XP (without PNP support)

Download and unzip the file into the newly created USB directory.
Now visit this other web page and download the PDF application note that
describes how to install the driver for your particular system.
