@wuxinygq Please read the form and fill in the issue with more detail. Stating "some screens do not work" with no details gives us nothing to work with.

This is a known issue @wuxinygq.

We will look to resolve in v0.7.9

TheOpponent commented

My SH1106 screen is also not working on Waveshare RP2040 Zero on 0.7.8 mapped to i2c1, where it did work in 0.7.6. On 0.7.8, the display shows garbage, with one row of text showing rapidly cycling random characters. Attempting to reset settings with the Danger Zone button disables the screen, but re-entering the i2c peripheral and pin settings does not enable the screen at all. A downgrade is necessary to restore screen functionality.

Hi @TheOpponent ,

As stated above this is a known issue with certain display types and will be looked into for a possible fix in the next firmware release.

Please use one of the test builds in PR #974 and comment on this issue with the type of display you're using, in addition to the information the screen displays.

Using v0.7.8-5-g6078ece for Waveshare Zero from #974, my SH1106 display on i2c1 reads:

Screen Type: 4
Screen Reg: 8
Detected Disp: 2
mikepparks commented

With the latest update to PR #974 the displays should be back in working order. We'll get it merged in for 0.7.9 once we have more confirmations that things are working.

Screen features in the most recent artifact for Waveshare RP2040-Zero now work as expected.
