ESP-IDF ANSI C12.18 Component

ANSI C12.18 component for Espressif ESP32 ESP-IDF framework

ANSI C12.18 is a communication protocol for two-way communication with a metereing device through an ANSI Type 2 Optical port. This component implements ANSI C12.18 funcitonalities over UART port, which can be attached to a optical-serial adapter to interface with the metering device.

Implemented Services

• Identification Service;
• Read (Total Read) Service;
• Write Service (Total Write);
• Security Service;
• Partial Read (offset/octet-count method);
• Partial Write (offset/octet-count method);
