MCU 使用GPIO 8080接口方式驱动ST7789V

ST7789V是一款液晶控制器芯片，它的接口方式是SPI或RGB接口，而不是8080接口。如果您想使用GPIO通过8080接口方式驱动ST7789V，您需要使用一个外部的GPIO转8080接口的芯片或模块，同时需要编写相关的驱动程序。具体的实现方式和细节，建议您参考ST7789V的数据手册和外部GPIO转8080接口的芯片或模块的文档。

使用stm32的gpio 8080接口的模式来驱动st7789v，点亮一个屏

驱动ST7789V液晶屏需要使用SPI接口，而不是8080接口，因此您需要使用STM32的SPI接口来驱动ST7789V液晶屏。以下是使用STM32的SPI接口驱动ST7789V液晶屏的一些基本步骤：

1. 配置SPI接口，包括时钟频率、数据位宽、时序模式等参数。
2. 配置STM32的GPIO口，将SPI的SCK、MOSI、MISO、CS等引脚对应到STM32的GPIO口上。
3. 初始化ST7789V液晶屏，包括复位、初始化命令等。
4. 发送数据到ST7789V液晶屏，包括图像数据、命令等。

具体的实现细节可以参考ST7789V液晶屏的数据手册和STM32的SPI驱动库。
