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

Overview

TopologyOther Topology
Input voltage1.44-4.3 V
IC revisionE1

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

  • CC1310 SimpleLink™ Wireless MCU ControlsSeven-Segment LCD Through GPIOs(Patent Pending Solution)
  • Only 4 COM, 2 Control, and 20 Segment Lines(26 I/Os total) Needed to Drive 80 LCD Segments(4-MUX, 1/3-Biasing)
  • Sensor Controller Peripheral Senses the CapacitiveTouch PCB Area and Reads Out the LMT70ASensors Periodically
  • Two-Layer PCB With HCA Form Factor Using a96-Segment LCD (4-MUX) and Cap Touch Area forLCD On/Off
  • Average Current: 835 nA at 3.6 V (LCD Off);338 μA at 3.6 V (80 LCD Segments On)

Typical applications

  • Sub-1GHz RF Enabled Subsystems for 433- or 868-MHz Bands With TI MCUs and Seven- Segment LCD
  • Internet of Things (IoT) Applications With TI MCUs and Seven-Segment LCD
  • Any Metering and Submetering Subsystems With Segment LCD Functionality Using TI MCUs Without On-Chip LCD Controller
