Description

This reference design describes the implementation of a low-cost, highly-flexible and modular keyboard controller using MSP430. Examples for MSP430F5529 and MSP430G2744, supporting I2C and USB are included.

Features
  • Supports standard matrix keyboards: this design shows an implementation using a 15x8 matrix but different keyboard layouts can be used
  • Independent of the communication interface: examples for USB and I2C are included
  • Supports multimedia keys
  • Can be implemented in practically any MSP430 platform: examples for MSP430F5529 and MSP430G2744 are included
  • Low power consumption
