Renesas chip clock desk lamp system

Overview

The clock desk lamp system based on Renesas chips uses IIC communication OLED screen to display the clock. At the same time, the touch function of the chip is used to control the high and low levels of the IO port to operate the light. At the same time, this version is also powered by a battery for portability. Because a battery is needed, a charging function is added. At the same time, a DS18B20 temperature sensor is also added, which can subsequently display room temperature.
During the implementation process, the difficulty lies in debugging. It may be due to lack of proficiency, and the ecology is not too complete, and many problems have not been found. Need to explore more on your own.
I drew a 3D shell, but since it was my first time to draw it, it wasn’t very successful and didn’t fit properly, so I won’t show the shell.
