ST7789

端口

基本上存在两种驱动方法 SPI和8080 8bit接口

需要使用的寄存器是一样的

引脚名 功能 SPI 8080 8bit
BLK 背光(1开0关) √ √
RST 复位(1启动0复位) √ √
CS_NE 片选 √ √
DC_RS 数据/地址 √ √
SPI_SCK 时钟 √ ×
SPI_MOSI 发送 √ ×
SPI_MISO 接收 √ ×
D0-D7 并行数据 × √
WR NWE写数据(上升沿有效) × √
RD NOE读数据(上升沿有效) × √

SPI

数据宽度8bits 其余默认即可

GPIO等级调到最高

SPI_DMA

DMA设置 默认即可 打开中断

SPI设置和上方相同

8080_GPIO

设置一整个GPIO组 例如PD0-PD7

可以整个GPIO组写加快速度

8080_FMC

设置为LCD 寄存器选择随意引脚即可

数据宽度8bits

注意时序 1-5即可 其余默认

片选 起始地址 中止地址
NE1 0x60000000 0x63FFFFFF
NE2 0x64000000 0x67FFFFFF
NE3 0x68000000 0x6BFFFFFF

写数据

SPI写函数使用 hal库的API即可

如下

复制代码 
HAL_SPI_Transmit(&TFT_ST7789_hSPI, &data, 1, 1000);
HAL_SPI_Transmit_DMA(&TFT_ST7789_hSPI, (uint8_t *)buf, len);
