Hello. I am starting work with a new project. The LCD with which they chose based on ST7789H2 driver and works through the SPI protocol, but instead of two lines MISO and MOSI, only one is used, which changes from MISO to MOSI. I have not met this before. Are there any configuration examples and driver for the K21F120 MCU with this type of SPI?
