TEMPERATURE SENSOR
Three switches provide the following functions:
• S1 – MCLR to hard reset the processor
• S2 – Active-low switch connected to RA4
• S3 – Active-low switch connected to RB0
Switches, S1 and S3, have debounce capacitors, whereas S2 does not, allowing the
user to investigate debounce techniques.
When pressed, the switches are grounded. When Idle, they are pulled high (+5V).
• RC oscillator (2 MHz approximately) supplied. This oscillator may be disabled by
• Pads provided for user-furnished crystal and two capacitors.
• Removable, 4 MHz, canned oscillator.
• 32.768 kHz (watch-type) crystal for Timer1.
A 5 kΩ potentiometer is connected through a series 470Ω resistor to AN0.
The pot can be adjusted from V
an A/D module.
By way of the modular connector (J5), the MPLAB ICD 2 can be connected for low-cost
debugging. The ICD connector utilizes RB6 and RB7 of the microcontroller for in-circuit
debugging.
This is a serial digital thermal sensor (TC74) connected to the 28 and 40-pin
microcontrollers via RC3 and RC4.
Communication is accomplished with the TC74 via it’s 2-wire I
port. This device has an address of ‘b1001101.
A 24L256 256K (32K x 8) serial EEPROM is included on the board to illustrate I
concepts.
An LCD display with two lines, 16 characters each, is connected to the 28 and 40-pin
sockets. There are three control lines (RA3:RA1) and four data lines (RD3:RD0).
A 5 kΩ pot may be installed into R20 to adjust contrast on the LCD. If this is done, R5
and R6 need to be removed.
