Setting up the Terminal Program
If you are an expert at setting up serial terminals and connecting serial devices then you can skim this section, but if
you’re not then follow along. There are two parts to this demo:
The first problem is fairly straightforward, simply connect your Chameleon PIC to your PC with the mini-USB serial cable.
The FTDI driver on the PC’s side virtualizes the COM port, so from the PC’s point of view it’s just another serial port.
Once you have the physical connection made then the next step is to get a terminal program up and running on your PC.
There are literally dozens if not hundreds of serial communications programs that you can find on internet, 99% of them
are free for a reason -- they are junk. There are a few that are actually very good such as:
You can also find them on DVD located here :
VT100 terminal running, the Chameleon’s serial port connected to the PC with the following settings on your terminal:
What we are going to focus on here is taking full advantage of the serial UART code and making a little “Guess My
Number” game that runs on the Chameleon PIC, but communicates via serial to a VT100 terminal running on the PC.
Figure 31.2 shows the demo program running.

Make sure that you have the serial selection switch in the DOWN position on the Chameleon (PIC mode).

However, in most cases, the only serial device you need to connect to the Chameleon is
the PC, and thus the USB to serial connection suffices for most applications.

"N81", no parity, 8 data bits, 1 stop bit.
115,200.
None.
80x24 or larger, 120x50 is a good choice.
