[Sipeed BL808 all-round board] Try to compile LVGL and replace DEMO [Copy link]

 

After we have set up the environment, we can look at the examples and then compile and test them. Let's start with the LVGL demo with a screen.

There are still many examples that can be tested. The ones given here are all independent. To see the source files behind them, we need to go to the SDK to view the specific header files and source codes.

As shown above, you can see a lot of our source code.

The following example uses the freeRTOS operating system, mainly to create the LVGL DEMO.

You can see that there are 5 demos in the source code. He built the first one and burned it in and it was the same as the document.

I modified it myself and turned it into LVGL_widgets routine, so that I can test other functions.

Just modify it in the main function. The test results are as follows:

I burned the program according to what they provided, using a virtual USB flash drive. This was also very fast. I just had to put it in and wait for it to exit and restart.

The porting of LVGL is still very convenient, and the interface it exposes is relatively standardized.
