What is it?

TM1650_STM8 is a library for the Arduino to interface with Seven Segment Display based on the TM1650 controller or compatibles (FD650B) for STM8s under I2C interface. Due to the Flash memory size limitation, it does NOT support input features (keypress scan).

This is a modified version of the Mozz_TM1650 library written by Mario Mikočević. It is ported from C++ to C syntax and is meant to be used with the sduino environment for the STM8.

This library is meant to have a minimal memory footprint.

Installation

Download the zip file. Then extract and copy to Sketch Location (You could check it from Arduino Preferences), usaually could be: Documents\Arduino\hardware\sduino\stm8\libraries

How it Works

To use this library, you must first connect your Display to the proper pins on the STM8s. The connections would be the following:

Others

The library allows to reduce the extra 67 bytes sketch size, defined by an macro variable TM1650_MEMORY_SAVER in file TM1650_STM8.h.
