Jesus,

You do not need to have any other program up and running except the Hyperterminal
program when testing the prototype card. The PIC micro controller is already loaded
with the software. We can discuss later on how to load a new software into the micro
controller.

First find the new port number that Windows did install when you installed the driver
for the USB to serial dongle.

1. Right click on My Computer icon on screen and select Properties
2. Click on Hardware folder
3. Click on the right middle button (right of small computer icon).
4. Click on the + on Ports (COM and LPT)
5. Make a note on WHAT new PORT windows has made for your USB dongle.

Use this port number when you set up Hyperterminal program.

Now, connect the 9 volt battery to the prototype board.

Groundloop.

Thank you @groiundloop!

If what you explain is to look on the device manager, I did it yesterday and today again and added the com3 to the hyperterminal.

Yesterday I tried to detect the device with the Mplab ide and could not. But you say that it is not needed at this stage.

Screen captures follow.

Jesus,

OK, it seems that your USB to serial dongle is correctly installed.

Select port 3 in Hyperterminal.
Now set up the Hyperterminal to 2400 bits/Sec, 8 data bits,
No Parity, 1 Stopbit, and None on the last entry.

Then check that you have a connected status in Hyperterminal by
looking at the bottom of the program frame.

Now connect the 9 volt battery to the prototype board a couple of times.
A menu should appear in the Hyperterminal window.

You do NOT use MPLAB to connect to a serial device. You use MPLAB
to make programs for the PIC micro, you then compile the program in MPLAB,
thus producing a HEX file. This HEX file must be transferred to the PIC16F88
by the use of a programmer hardware like the PicKit2 or similar.
You then use the PIcKit2 program to transfer the HEX file to the PIC micro controller.

Groundloop.

@groundloop

I have the pickit2 board and programmer. Can I put the pic16F88 on the pickit2 board and reprogram the pic controller with one of your downloaded files?

If so which one I must try first?

Jesus
