#The7thLiChuangElectricityContest#DHT11 temperature and humidity oled digital display

* 1. Introduction to the project function:
A small ornament that displays temperature and humidity. The epidemic has kept us under lockdown for two weeks, which is so miserable. I will make the shell later when I have time.
 
*2.
Self-made project attributes
 
* 3. Open source agreement
GPL3.0
 
*4.
After testing the hardware part, this N32 can be downloaded using stlink, which is well received. In addition, the OLED uses a 6-pin SPI interface.
 
*5. For the software part
, use keil. If you have time, you can tinker with cross-compilation yourself.
When I was about to copy the DHT11 code directly from the Internet, I found that the IO port could not use bit-banding to set the output. After checking the manual, I saw that the general IO port of this N32 chip could not be operated with bit-banding. The official bit-banding memory mapping did not cover the general IO, which wasted several hours ╮(╯＿╰)╭ *6. See the project
