Basic Functions
Starting Communications
Select the Pull-down menu Options → Enable Eval Board to begin communi-
cations between the GUI Control Panel and the PICDEM ? MSC1, as shown
in Figure 2.4.
Figure 2.4: Enable Evaluation Board
Select the Input/Output tab and note the Port A and Port B functions to verify
that the GUI is communicating with the Evaluation Board.
Note:
The MCLR function in Port A and the Dgtl Out: RB4 and DGtl In:
RB5 functions are shown in gray when the GUI software is initially
communicating with the Evaluation Board.
Serial Communications with the PICDEM ? MSC1 Evaluation Board
Since the PIC16C781/782 does not have a UART peripheral, serial communi-
cations are "bit-banged" with software timing loops. Timing calibration is per-
formed automatically each time the board is enabled. The Evaluation Board
clock is the internal RC oscillator.
One characteristic of this oscillator is that it may drift slightly in frequency with
changes in temperature. If you expect to use the Evaluation Board over a
wide temperature variation, you will need to recalibrate the communication
timing at each new operating temperature.
You can recalibrate at any time by de-selecting the PICDEM MSC1 board by
selecting Options → Enable Eval Board, then selecting Options → Enable Eval
Board a second time to recalibrate and re-establish communications. When
the connection is made, all registers will be initialized to the values set in the
GUI. This procedure of disconnecting, then reconnecting, is also useful if you
accidentally RESET the PIC16C781/782 with a stray probe or ground strap.
PERIPHERAL ORGANIZATION
The PIC16C781/782 peripherals are organized as tabbed pages (see Figure
2.1), one for each major peripheral function. These include:
? Input/Output
? Analog-to-Digital Converter (ADC)
? Digital-to-Analog Converter (DAC)
? Comparators and Operational Amplifier
? Programmable Switch Mode Controller (PSMC)
