Lcd.off and Lcd.on problem

[crouse12]

I found that python editor beta 2.1.0-beta.6 for microbit v2 has a bug for led screen.
When I use the following python program, led screen on microbit v2 has some errors.
Can anyone help me?
PS. python editor Editor Version: 2.0.1 for microbit v1 does not have this bug

Thanks for the report. The issue is that pin10 is connected to the display and display.on() does not fully reset the display, so the pin10.write_analog(0) has a side effect of leaving the last column all lit up.

@microbit-carlos would we expect uBit.display.enable() to fully reset the display?

Yes, I think it should: lancaster-university/codal-microbit-v2#21

pin10 is also a display pin on V1, and this doesn't seem to be an issue in V1.

This has been fixed in CODAL and will be included in the next MicroPython update: lancaster-university/codal-microbit-v2#21 (comment)

I tested this with the latest build using the latest CODAL and it is fixed.
