【专题STM32F03】 使用 STM32Cube\Repository\STM32Cube_FW_F1_V1.8.5 中例程由ST7735硬SPI串口屏修改驱动ST7789硬SPI串口LCD屏

1）修改Project

\STM32Cube_FW_F1_V1.8.5\Projects\STM32F103RB-Nucleo\Demonstrations\Adafruit_LCD_1_8_SD_Joystick

2）接线 （见 stm32f1xx_nucleo.h）

LCD_LED_PIN 接高电平

LCD_CS_PIN    接PB6

LCD_DC_PIN    接PA9

LCD_SPI_CLK   接SPI1 ，PA5

LCD_SPI_SDA   接SPI1 ，PA7

3）修改代码

st7735.h
