Last time we tested our sht20 temperature and humidity sensor, which has an IIC interface. This time we will use the OLED screen to display some content.

We just need to make changes to the original SHT20 driver.

It is consistent with the address we scanned.

We modify its sending to send a total of two formats, one data and one command.

The main function here is to initialize, then clear the display, and then display the string below.

Thanks for sharing. It's a good opportunity to learn from it. Maybe I'll have a chance to use it in the future.
