Here is details:

I2C_SDA = 6
I2C_SDL = 7
I2C_INT = 17
I2C_RST = 16

I’m trying to get the same board to work. Have you solved this?

Not yet. I’m completely new to Embedding system. I think there are two ways to make it work: 1. Wrap a micropython driver in LVGL way. 2. Compile with C driver.
Unfortunately, I still have no idea to solve it currently.
