Using the Demo Software
3.2
FIRMWARE ROUTINES FOR COMMUNICATING WITH MICROWIRE EEPROM
USING SYNCHRONOUS MODE OF USART MODULE
The PICDEM LCD board also helps you to use the Synchronous mode of the USART
module to communicate with a Microwire EEPROM device. Before using these
functions, the MWMEE.Def and USRTPol.Def files need to be edited as per your
requirement.

Description
This function erases a location in the EEPROM. The
location should be specified in AdrsReg.
This function writes the data specified in DataReg into
a location in the EEPROM. The location should be
specified in AdrsReg.
This function reads a location in the EEPROM. The
location should be specified in AdrsReg. The data is
available in WREG.
This function enables the write to EEPROM.
This function disables the write to EEPROM.
This function erases the entire EEPROM.
This function writes the data specified in DataReg into
a location in the EEPROM.
3.3
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
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 5.10V on the
LCD using the LCD module. Voltage is continually updated until the mode is
exited by pressing either the S1, S2, S3 or S4 switch.
2. Thermometer
This mode uses the A/D module to measure the voltage of the thermistor R11
through analog channel AN1 and converts to temperature in Celsius 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, S2, S3 or
S4 switch.
3. Battery Voltage Indicator
This mode uses the HLVD module on the PIC18F8490 device to find the battery
voltage range and displays the voltage (4.5 V+, 4.25 V+....2.0 V+) on the LCD
using the LCD module. Battery voltage is continually updated until the mode is
exited by pressing either the S1, S2 or S4 switch.
4. Clock
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.The clock keeps running continuously until the mode is exited
by pressing either the S1 or S2 switch. By exiting the Clock mode, the Voltmeter
mode is entered.
