• PC keyboard
• HD44780 LCD
• 2- and 3-wire libraries with bitwise pin control
• Scriptable binary bitbang, 1-Wire, I2C, SPI, and UART modes

Features

• 0-5.5volt tolerant pins
• 0-6volt measurement probe
• 1Hz-40MHz frequency measurement
• 1kHz - 4MHz pulse-width modulator, frequency generator
• On-board multi-voltage pull-up resistors
• On-board 3.3volt and 5volt power supplies with software reset
• Macros for common operations
• Bus traffic sniffers (SPI, I2C)
• A bootloader for easy firmware updates
• Transparent USB->serial mode
