Reference Design for Segment LCD Control Using GPIO Pins to Increase System Flexibility

Description

The TIDA-00848 reference design provides an innovative solution for adding LCD functionality to any Smart Grid or IoT application: where seven-segment LCD operation is required but the LCD dsiplay does not have to be always on. Using a few resistors and optimized GPIO control software on a CC1310 SimpleLinkTM Wireless MCU: a seven-segment LCD support is implemented. This design approach can be used with any TI microcontrollers without an on-chip LCD controller module.

Features
  • Innovative solution for driving Seven-segment LCD thru GPIOs by CC1310 SimpleLink Wireless MCUOnly 26 I/Os needed for driving 80 seg-ments of a 4-MUX: 1/3-biased LCDSensor controller peripheral senses the capacitive touch PCB area and reads out the LMT70A sensors periodically2-layer PCB With HCA form factor using a 96-segment 4-MUX LCD and cap touch area for LCD ON/OFFAverage current: 835 nA @ 3.6 V (LCD OFF); 338 uA @ 3.6 V (80 LCD segments ON) under TI RTOS framework
