PICDEM™ LCD 2 DEMONSTRATION KIT USER’S GUIDE Chapter 2. Getting Started The PICDEM LCD 2 may be used as a stand-alone board with a preprogrammed device, with an In-Circuit Emulator (ICE) or with an In-Circuit Debugger (ICD). For a list of PIC® microcontroller compatible ICEs or ICDs, please refer to the “Microchip Development Systems Ordering Guide” (DS30177). 2.
PICDEM™ LCD 2 Demonstration Kit User’s Guide 2.2 PICDEM LCD 2 USED WITH AN IN-CIRCUIT EMULATOR OR IN-CIRCUIT DEBUGGER To use the PICDEM LCD 2 with an In-Circuit Emulator (ICE) or In-Circuit Debugger (ICD), refer to the tool’s user’s guide for instructions on how to power-up and configure the ICE/ICD, as well as how to connect to target boards. Configure the PICDEM LCD 2 for the desired oscillator as described in Table 2-1. Refer to the ICE/ICD user’s guide for any oscillator configuration requirements.
PICDEM™ LCD 2 DEMONSTRATION KIT USER’S GUIDE Chapter 3. Using the Demo Software The demo programs are preprogrammed into the sample devices. Also, this program is included on the CD-ROM program disk for user reference. This demo program uses the functions or macros provided by the firmware LCD driver module to display the required characters, strings or icons on the LCD. 3.1 DEMO FIRMWARE OPERATION The demo firmware is made up of four components, which are individually displayed on the LCD.

Board Technical Information A.6 OSCILLATOR OPTIONS The on-board firmware uses the internal RC oscillator running at 8 MHz. • Internal RC oscillator running at 8 MHz can be used. • Pads provided for user-furnished crystal/resonator (Y2) and two capacitors (C16 and C17). • Socket provided for a canned oscillator (Y3). This oscillator can be disabled by removing jumpers, JP9, JP11 and JP12. • 32.768 kHz (watch-type) crystal for Timer1 (Y1) is always connected to RC0 and RC1. A.
PICDEM™ LCD 2 Demonstration Kit User’s Guide A.11 TEMPERATURE SENSOR A 10 kTC thermistor (R11) is provided to sense the temperature. It is connected to AN1 (RA1) through the jumper, JP5. An optional unpopulated TC77-based circuit is provided to read the temperature serially using the USART module. The jumpers, JP15 and JP16, are to be connected and RA1 of U1A should be made digital to be used to enable TC77.
Board Technical Information A.14 POWER SUPPLY There are four ways to supply power to the PICDEM LCD 2: • A 3V button cell (CR2032) can be plugged into BT1. • A 9V, 100 mA unregulated AC to DC supply can be plugged into J5. A power supply can be purchased through Microchip Technology (Part Number AC162039). • A 100 mA regulated DC supply of maximum +5V can be connected to the hooks provided. Note: There is one J15 jumper associated with the power supply circuit.
PICDEM™ LCD 2 Demonstration Kit User’s Guide A.14.1 Using the Adjustable Voltage Regulator The PICDEM LCD 2 board features an adjustable voltage regulator, the venerable LM317. It is U3 on the board, and can be recognized by the SO-223 package on the upper left side. Nearby, there is a header, J10, and two resistors, R25 and R26. R25 and R26 are used to set the output voltage of the LM317. By default, R25 = 1K and R26 = 330R, which results in an output voltage of 5.0V.
Board Technical Information As stated previously, R25 = 1K and R26 = 330. You can see that without R102 and R101, VOUT = 1.25V(1+ 1K/330R) = 5.04V. For a desired VOUT, first solve for R2, given R1 = R26 = 330R. Then, knowing R2 and R25, solve for R102. Determine the nearest available resistor value for R102 and recalculate the resulting VDD to make sure it does not exceed the maximum VDD for the part you will be using.
