Debug Log 1
Familiar with relevant information
This is the first time I use the CDK development environment and 2601 chip. I have familiarized myself with it based on the information on the official website and forums. I feel that the platform is quite interesting.
The main reference and learning links are as follows:

After I got the board, I tried to download helloworld, so easy, and then I wanted to see what the LVGL effect was on this OLED. It was very large and the resolution was really low, haha
The version of lvgl is still at v7, but the official website has already reached v8. It feels like the update is a bit slow.
The official driver of oled uses io to simulate spi, not the hardware spi of the chip, which is a bit regrettable
Later, we will consider optimizing and transforming it into a hardware SPI driver.
Transplant driver for 0.96-inch color screen
Just connect the line according to the interface of the OLED screen
Use the official gui demo to directly modify the driver file of the OLED and lv_conf.h, involving the functions of drawing points and initialization
The code has not been organized, so just take a look at it. The key files are in the attachment for your reference. These files will be modified and optimized later.
