What kind of single chip microcomputer is more suitable for e-sports?

In fact, you just need to find something familiar.

5 1 single chip microcomputer chooses AT89S52, and many ready-made programs can be found, which is beneficial to development. It has 8K ROM, which is enough for general occasions.

More advanced ones can use AVR's mega series. I prefer mega 16 in the competition, which is not expensive. It basically has all the functions that a single chip microcomputer should have. 16K ROM is cool to use, and the speed is not picky. If you don't like it, you can use mega 128, which is more expensive. 128K ROM is enough for you to make up an 8-bit Nintendo game. Mega 128 timer is extremely powerful and has many IO ports, which eliminates the trouble of expanding IO. This is a pretty good microcontroller, and you can do all the rest of AVR. There are many tutorials online.

430 is not necessary. In fact, there are really not many people who want to give full play to 430.
