Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

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 Development Systems Ordering Guide” (DS30177).

2.1 PICDEM LCD 2 AS A STAND-ALONE BOARD – PREPROGRAMMED DEVICE

The PICDEM LCD 2 may be demonstrated immediately by following the steps listed below:

• Apply power to the PICDEM LCD 2. For information on acceptable power

microcontroller compatible ICEs or ICDs, please refer to the “Microchip

sources, see Appendix A. “Board Technical Information”.

Note: In the event that the preprogrammed PICDEM LCD 2 Demonstration Board

with the PIC18F85J90 PIM does not operate, check the following conditions:

- The jumper, J15, is configured as per the power supply used. The slide switch, S6, is switched to C.

- JP1, JP2, JP6, JP18 and JP19 are connected.

- The middle two jumpers of J14 are connected.

- JP9 and JP10 are connected.

- J11 connecting POT to AN0 and JP17 connecting V

The status of all other jumpers will not affect the preprogrammed demonstration.

Refer to Figure A-1 in Appendix A. “Board Technical Information”.

CC to I/O.

To reprogram the sample device, the following will be necessary:

1. User source code may be programmed to the device or the sample program may be restored from the file on the included CD-ROM.

2. An assembler, such as the MPASM™ Assembler (available with MPLAB IDE), or a compiler, such as MPLAB C18 C Compiler (PIC18XXXX/18XXJXX devices only) must be used.

Source code must be assembled or compiled into a HEX file before it can be programmed into the device. Microchip Technology’s MPASM Assembler or MPLAB C18 C Compiler may be used. Both are compatible with MPLAB IDE; however, other assemblers/compilers may be used.

3. Once the sample program is in the HEX file format, it can be programmed to a Flash device using an MPLAB ICD 2 or PM3 with an ICSP™ module. Microchip Technology’s MPLAB ICD 2 is compatible with MPLAB IDE.

If the code protection bit(s) have not been programmed, the on-chip program memory can be read out for verification purposes.

PICDEM™ LCD 2 DEMONSTRATION

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. The PIC microcontroller’s internal RC oscillator is used as the system clock source.

1. Voltmeter (F1) This mode uses the A/D module to measure the voltage of the R44 pot through analog channel AN0, and displays a voltage between 0.00V and 3.30V on the LCD using the LCD module. Voltage is continually updated until the mode is exited by pressing either the S1 or S2 switch.

2. Thermometer (F2)

This mode uses the A/D module to measure the voltage of the thermistor R11 through analog channel AN1, and converts to temperature both in Celsius and Fahrenheit and displays the temperature on the LCD using the LCD module. Temperature is continually updated until the mode is exited by pressing either the S1 or S2 switch.

3. Clock (F3)

This mode uses the Timer1 module and a 32 kHz clock crystal. Once this mode is entered from the main menu, the Real-Time Clock will start counting from 00:00:00. The S3 switch is used to increment minutes and the S4 switch is used to increment hours. To perform the increment operations, press and hold the switches. The clock keeps running continuously until the mode is exited by pressing either the S1 or S2 switch.

4. Charge Pump and Software Contrast (F4) This mode is available only for the PIC18F85J90 and PIC18F87J90 families of devices and uses the on-board charge pump and LCD voltage regulator. The LCD module is configured in Charge Pump mode and software contrast is achieved by either pressing S3 to increase the contrast or S4 to decrease the contrast until the mode is exited by pressing either the S1 or S2 switch. By exiting this mode, the Voltmeter mode is entered and retains the contrast level.

Since the glass used on the PICDEM LCD 2 operates at 3V, there is a voltage protection circuit on the LCDBIAS3 pin, which is enabled in the default configuration. When enabled, even if the V

DD is greater than 3V, it regulates the LCDBIAS3 voltage such

that it always maintains the value to 3V. This is not necessary for operation of the LCD module, but it is a protection circuit to prevent accidentally applying voltages higher than 3V to the LCD glass present on the board.

A.3 LED DISPLAY

Shaded cells indicate the pins that are remapped to the corresponding pin on the PIM.

Two green LEDs are connected to RC3 and RC4 of U1A through the J14 pins, 1, 2 and 7, 8 (outer ends), respectively.

One green LED is provided to determine whether there is power to the LCD 2 Demonstration Board (LED on) or not (LED off).

Note 1: For the PIC18F85J90 and PIC18F87J90 PIM, the RG2 and RG3 pins are

connected to RC3 and RC4 of U1A, respectively.

2: For the PIC16F17 PIM, the RD1 and RD2 pins are connected to RC3 and

RC4 of U1A, respectively.

3: For the PIC18F8490 PIM, the RC3 and RD4 pins are connected to RC3

and RC4 of U1A, respectively

A.4 CHARGE PUMP AND VLCAP

For charge pump mode operation in PIC18F85J90 and PIC18F87J90 devices, it is required that RC3 and RC4 of U1A connect to charge pump capacitor C7 through the J14 pins, 3, 4 and 5, 6 (inner pins), respectively.

A.5 RESISTIVE LADDER VERSUS CHARGE PUMP

The switch, S6, allows the connection of either the resistor ladder or the capacitors to the BIAS pins to generate the BIAS voltages for the LCD operation. For the Charge Pump mode operation in PIC18F85J90 and PIC18F87J90 devices, it is required that the S6 switch is flipped towards C and the VLCAP is connected through the inner jumpers of J14. For the resistor ladder, S6 must be flipped towards R. The R45 potentiometer controls the contrast to the LCD in the Resistive Ladder mode.

A.5.1 Jumper JP21

When jumper JP21 is on, the LCDBIAS0 is physically tied to ground. The jumper needs to be on for PIC18F85J90 and PIC18F87J90 devices when the bias voltages are generated through the resist or ladder.

VLCDBIAS Regulated (Default): This is the recommended jumper setting to operate when using external supply. This configuration allows the VLCDBIAS to be regulated to 3V even if the V

of the board is higher than 3V.

VLCDBIAS = 3V, External Power

b) Battery Operation: This is the

recommend jumper setting when operating on a battery. In this configuration, VLCDBIAS is directly connected to the battery voltage.

c) External Supply with VLCDBIAS

Unregulated: This is not recommended to use with on-board glass as voltage higher than 3V may damage the glass. If an external glass is connected to J2 and is capable of handling higher voltages, then this jumper setting allows V

CC to connect

directly to the VLCDBIAS when an external power supply is used.

EXAMPLE A EXAMPLE B EXAMPLE C

Note: For all examples shown above, the voltage regulation on the VLCDBIAS for 3V is not required for the

regular operation of the module or device. It is added here for additional protection for the glass since the board is capable of generating 3.3V or 5V depending on the PIM being used.

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. This

jumper must be correctly connected to select the required power supply. Refer to Figure A-11 for jumper setting examples.

MPLAB ICD 2 users may use the ICD to power the target board to 5V, up to 200 mA, for the following devices only: PIC18F8490, PIC16F/LF/1946/7, PIC16F946 and PIC16F916. The PIC18F85J90 and PIC18F87J90 families of devices do not support this capability.

The default power on the board is 5V. The board voltage can be varied based on resistors populated on the PIM in conjunction with the processor being used.

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.

The reason an adjustable voltage regulator is provided is so that the PICDEM LCD 2 Demonstration Board can be used with a wide range of LCD PIC microcontrollers. The PIC18FXXJ90 family of devices tolerates a maximum V PIC18FXX90, PIC16F91X and PIC16F946 tolerate a maximum V adjustable voltage regulator allows a different V

DD to be provid ed for PI C18FJ device s

and PIC18F and PIC16F LCD devices. The switching between 3.6V and 5.5V parts is very convenient. The plug-in module

boards are populated with the R101 and R102, appropriately, according to the processor module requirement which mates with the daughter board/emulator header that surrounds the ICE module (U1A). J10 on the PICDEM LCD 2 board is intended to connect with the 3-pin header on the plug-in module. This allows the resistors, R101 and R102, on the plug-in module to be connected in parallel to the resistors, R25 and R26. This way V

DD can automatically be adjusted to the voltage appropriate to the part

soldered onto the plug-in module . The plug-in module is prepopulated with the values shown in Table A-22:

DD of 3.6V, whereas the

DD of 5.5V. The

For V

(1% resistors are recommended for precise adjustment of V Now, let’s look at how to determine R101 and R102 if a different V

DD.)

DD is desired. First,

it is a good idea to look at the data sheet for the LM317 to understand how the voltage is adjusted. We will not duplicate all the details here. The following equation is taken from an LM317 data sheet:

EQUATION A-1:

VOUT = VREF (1+ R2/R1) + IADJ * R2

ADJ is minimized by the LM317, so it can be assumed to be zero or at least very small.

REF =1.25V; it is the reference voltage developed by the LM317 between the output

and adjustment terminal. That gives us the following equation:

EQUATION A-2:

VOUT = 1.25V(1+R2/R1) R2 = R25 || R102 = (R25* R102)/(R25+R102) R1 = R26 || R101.= (R26* R101)/(R26+R101)

DS51662C-page 50  2010 Microchip Technology Inc.

Board Technical Information

As stated previously, R25 = 1K and R26 = 330. You can see that without R102 and R101, V

For a desired V R25, solve for R102. Determine the nearest available resistor value for R102 and recalculate the resulting V part you will be using.

Table A-23 shows values for R101 and R102 for different V R25 and R26 on the PICDEM LCD 2 Board are left as their default values of 1K and 330R.

OUT = 1.25V(1+ 1K/330R) = 5.04V.

OUT, first solve for R2, given R1 = R26 = 330R. Then, knowing R2 and

DD values, assuming that

DD VALUES

Recommended operating voltages for the various PIMs are:

• PIC18F85J90 and PIC18F87J90 families of devices – 3.3V

• PIC18F8490 family of devices – 5V

• PIC16F917/914 devices – 5V

• PIC16F946 – 5V (when operating on an external 9V DC supply)

• PIC16F1946/7 – 5V

• PIC16LF1946/7 – 3.3V

A.14.2 Slide Switch (S6)

The slide switch allows choosing the BIAS values, either generated by the resistor ladder, or by the capacitive charge pump. When S6 is switched to the left, the LCDBIAS pins of the microcontroller are connected to the resistor ladder. When S6 is switched to the right, the LCDBIAS pins of the microcontroller are connected to the capacitor network.
