KT LCD9 - firmware upgrade?

[apaczenko1993]

Hi, quick question. Have any of you tried to upload modified software to this display? From what I can see, after removing the PCB, the controller placed there is a copy of STM32F103RBT6, and the TFT display is hj1808-03fpc-a1. The display itself is based on the ST7735S chip, so it can be controlled via SPI. If any of you have any experience with KT series displays, please let me know
