I`m using esp32 devkit v1 and P10 WO (single color) andmain solution is downgrading esp kernel to 2.0.2 version. On 2.0.14 ver CLK LAT and DR pin was 0V. image in board manager choose more older version for esp32

here is my wiring image brown wire is DR (or R on another version of p10 matrix) connected to D23 on esp32 blue wire is LAT (or LCLK) connected to D2 green wire is CLK connected to D18 yellow wire is B connected to D21 red wire is A connected to D19 purple wire is OE (or enable) connected to D22 black wire is gnd connected to any gnd esp`s pin

here is normal voltage image OE pin image A pin image B pin image CLK pin image LAT pin image DR pin

Any ideas on how to make it work on latest versions and using platformio?

I have a library for Arduino Uno which I've tested for several times. but I need a good one for STM32 controllers using CubeIDE or Keil. Thanks
