【RA】Electronic calendar +664942A

Introduction

klx, the design and production of the Renesas MCU electronic calendar based on the RA-Eco-RA2E1-48PIN chip. The board is equipped with additional functions such as over-current protection, programming serial port, and lithium battery interface.

Welding and actual pictures

There is nothing to say about welding, just solder it directly. I remember that I still had a few varistors left on hand, but I couldn't find them, so I didn't solder them on.

The actual picture is as follows

Code development and demonstration videos

The code development this time directly used the method explained by the teacher during the live broadcast. Visual programming is quite fun, but it is a bit uncomfortable to understand the English. Also, there are many documents on the chip in English, and it is a bit confusing to use a translator. The display screen uses IIC Driver, refer to the example of RA2E1 introductory development document.

But since the event is coming to an end, I haven't written any other functions. I originally wanted to write a driver for WB2812, but I couldn't find a good way. If you have any ideas, please comment and I'll tinker with it.

The touch buttons cannot be used because I don't know how to debug them, so can anyone who knows how to debug them with j-link tell me in detail, including what hardware needs to be purchased.
