10 days based on stm32f401ret6 smart lock project practice day 1 (environment construction and new construction)

One 、 Environment building

1、 install keil5

2、 Install support package
Here, install the support package as required , Yes F4 and F1 The support package

What's good about the installation keil5 Open the new project to see the chip selection

3、 Crack software

Be careful ： Run as administrator keil5

4、 Install serial port driver and downloader driver

Let's download the downloader driver

Two 、 New project

First, we create a folder , Names can be chosen at will , You can put it anywhere

Here the folder is set up , And then I'm going to keil5 Do the following


Put the document in protect Under the folder
