I previously had a problem with the RT 1062 LCD and resolved it, but the github you mentioned is not opening and the LCD does not work even if I run the IDE4.1.5 LCD example.
The examples were rearranged, you can still find it on github, but you should have the latest working examples in the IDE if you let it update the resources. Can you post the script that’s not working ?
I’m using H7 Plus to make a simple defect detection code
I purchased RT1062 because the H7 Plus model was not supplied, and when I connected, IDE and firmware were updated,
H7 Plus, which was previously used, is also updated with firmware, and the existing code does not run.
Because of import lcd,pyb, it is assumed that neither related code works.
If the firmware version doesn’t fit, can you lower the firmware version?
And can you check the firmware version of the current product?

led_B.off()Hi, you need to update your code. The API for LCD control was changed. Please see the LCD shield example and update your code.
For H7 Plus, the LCD shield works fine by syntax conversion to lcd.display(img) → lcd.write(img). However, for RT1062, the LCD does not work with the code below
import sensor
import display
sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA2) # Special 128x160 framesize for LCD Shield.
lcd = display.SPIDisplay()
while True:
lcd.write(sensor.snapshot()) # Take a picture and display the image.
Hi, there’s a risk of shooting the shield against the board on the RT1062. The spacers included in the headers baggie are to reduce that.
Please check that the shield is not shorting against any of the header pins.
The same code definitely works with the current released firmware. So, if the system is not working it’s either a shorting issue or bad soldering.
