An open-source hardware board to prototype with Atmel's AVR8 microcontrollers (ATMEGA164 for now), JTAG live-debuggable, including a versatile C library for common peripherals and external sensors.

Core features:

• Busy-loop delays
• External interrupt inputs
• Internal ADCs
• Interrupt-driven UART communications
• GPIO
• PWM generation with programmable frequency
• SPI bus
• System tick clock with 100 μs resolution

Additional modules:

• Absolute encoder EMS22A
• Decoder for differential quadrature encoder (Interrupt-driven, up to ~300 K pulses/s)
• Digital-to-Analog (DAC) converter MAX5500
• imu_lsm9ds1: SparkFun LSM9DS1 9DOF IMU. Forked and adapted from here.
• lcd: Support for LCD displays via a I2C port expander. Forked and adapted from here.
• ad7606: Support for the Analog-to-Digital (ADC) chip AD7606.

• Board schematics
• C library: sources, Doxygen HTML reference. Tested with GNU GCC within Atmel Studio.
• FTDI chip EEPROM XML image, to be grabbed with FTPROG.
