Show picture

Displaying the picture is very simple. You can use the lcd module directly and call the function to display it, as follows:

import lcd, image


img = image.Image("/sd/test.jpg")

But different screen initialization sequence may be different. There are many optional parameters in lcd.init. See the description of API document for details. Common ones are as follows

For IPS screens, you need to reverse the color:


For the screen is not very good, you need to lower the frequency, or if you are good, you need to overclock:

lcd.init(freq = 15000000)

In addition, you can also set the rotation direction of the screen:


The parameters are 0~3, which respectively represent clockwise rotation 0 degrees 90 degrees 180 degrees 270 degrees
