Using Breadboard Kit with ST7796S displays lines across the sceen

[webwarrior]

Hi,

I cloned the repo from https://github.com/geeekpi/pico_breadboard_kit/tree/pico2 .

I build it for the PICO_BOARD=pico_w, and I see lines across the screen.

Everything else seems to work fine, including the GT911 touch pad.

When I build this for the PICO_BOARD=pico, it works.

It obviously will not work for the PICO_BOARD=pico2, even if this is a pico2 branch, because we will have to wait 3 more years until we can build stuff for the pico2, even if the instructions in the repo branch mentions:
cmake -DCMAKE_BUILD_TYPE=Debug -DPICO_PLATFORM=rp2350 -DPICO_BOARD=pico2 -DPICO_RP2350=1 FREERTOS_KERNEL_PATH=~/pico_breakboard_kit/components/FreeRTOS ..

Loading the uf2 file from the build to the pico 2 just crashes and I can never get that to work for the pico 2

How can I fix this problem?.

Is it some kind of refresh rate, or buffer issue?

I have the same issue. ZIP file demo provided at https://wiki.52pi.com/index.php?title=File:Pico_breadboard_kit_Plus_verison_demo_firmware.zip (hello_world.uf2, not hello_world(fromgithub).uf2) works properly but the fromgithub uf2 and building it from repo result in bars of static. Have tried changing clock speed and buffer to no avail. Previous commit seems to be for a different display(240x240, different pins) so also does not work.

Nevermind, rebuilding with the exact build string provided in the wiki does work properly with the screen on my end: cmake --no-warn-unused-cli -DPICO_OPTIMIZED_DEBUG=1 -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug ../
