TIDM-KEYBOARD
Keyboard Controller Using Low Power Microcontroller
TIDM-KEYBOARD
Overview
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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
