Microchip PIC Board, 40-pin, 4x7 LED, RS232, IR, USB option US$40.00

Microchip PIC Board, 40-pin, 4x7 LED, RS232, IR, USB option

Feature-rich development kit for 40-pin PICs, with in-circuit serial programming/debugging and monitoring support. Includes PIC16F877-20/P microcontroller.

Because they contain a superset of the peripherals found in lower-pin-count devices, knowledge and experience gained on the 40-pin devices applies to nearly all PIC microcontrollers. This board includes all the circuitry necessary for you to experiment with most of the microcontroller's on-chip peripherals and several external peripherals.

PIC Development Board Features

  • Two potentiometers connected to the A/D converter inputs
  • Photoresistor connected to the A/D converter input
  • Microphone with preamplifier connected to A/D converter input
  • Thermo sensor
  • 24LC01 - I2C Serial EEPROM
  • Sockets for other types of serial EEPROMs (MicroWire - 93xx, SPI - 25xx)
  • RS232 driver and 9-pin SubD connector
  • 24-pin DIP socket for installation of Asix USB-to-UART or USB-to-Serial module.
  • IR LED (transmitter)
  • IR receiver with 36 kHz filter and demodulator
  • 4-digit, 7-segment LED display
  • 10-level LED bargraph
  • Interface for dot-matrix alphanumeric LCD
  • Power and Application LEDs
  • 8 pushbuttons
  • Buzzer (connected to the PWM output pin)
  • Crystal 3.2768 MHz
  • Position to connect RC oscillator
  • Position for crystal
  • Reset button
  • Connector for In-Circuit Serial Programming/In-Circuit Debugging (such as with PRESTO)
  • Connector for Application Monitoring (such as with SIGMA)
  • Expansion connector with all microcontroller signals
  • DIP switches for connecting/disconnecting the peripherals
  • Regulated 5V power

Power input can be 9 to 12V. A minimum 300mA is recommended.

Using one of the DIP switches, you can turn off the on-board oscillator so that you may use a crystal or RC oscillator of your own.

There is a USB port on the board which can be utilized instead of the serial port only if you install a USB-to-UART module into the 24-pin DIP socket. A module is not included.

The PVK40's expansion connector was designed for a SPINET4PVK module which would give you an Ethernet port and Ethernet-to-SPI controller.

There are more than 20 code examples -- most of them in three versions:

  • PIC16 Assembler (for PIC16F877A and compatible)
  • PIC18 Assembler (for PIC18F4520 and compatible)
  • C language (for PIC16F877A and compatible, plus Atmel AVR ATmega64)
These examples range from very basic programs for the first-time user (e.g. Wire and Blink), simple programs that control peripherals, through to complex programs like Piano or Sound Recorder.

The assembler code examples can be compiled using Microchip MPLAB. The PIC C examples require the free PICC Lite compiler from Hi-Tech Software. The AVR code examples can be utilized with the free GNU tools.
