The AVR Project Board is a complete and easy-to-use development board for Atmel ATmega32 and compatible microcontrollers. The board comes with an ATmega32 installed, and includes the following interface circuitry: - 4×4 Keypad Matrix
- I2C Real Time Clock (DS1307)
- I2C EEPROM (24C256)
- Alphanumeric LCD, 16 characters by 2 lines
- MicroSD Card slot
- Switches
- RS232
- Buzzer
- LEDs
- IR transmitter LED
- IR receiver with comparator
- TSOP1783 IR Receiver
- Temperature Sensor
Header pins provide access to these circuits. A pack of 20 F-F jumper wires is included for facilitating connections. The board has a 5×2-pin ISP connector (top view on target board) for programming the microcontroller using an AVR ISP Programmer. AVR Project Board Setup By default, the ATmega32 on the board has JTAG enabled which prevents I/O operation for some PortC pins, and is set to use its 1 MHz internal oscillator instead of the 4 MHz external oscillator on the board. To have access to all the PortC pins, be sure to set the following fuse bits: To use external 4 MHz oscillator - High Fuse Bit — 0xD9
- Low Fuse Bit — 0xee
To use internal 1 MHz oscillator - High Fuse Bit — 0xD9
- Low Fuse Bit — 0xe1
