SPI驱动0.96/1.3寸 OLED屏幕，易修改为DMA控制

發布時間：2023/12/9 编程问答 28 豆豆

生活随笔收集整理的這篇文章主要介紹了 SPI驱动0.96/1.3寸 OLED屏幕，易修改为DMA控制小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

OLED SPI 端口定義

本節引自STM32驅動0.96寸OLED液晶屏(12864液晶屏) —— 小牧同學

兩種屏幕的引腳數不一樣，左邊的有7個引腳，而右邊的只有6個。其次，端口的標號也不完全一樣，第一個分別標為GND，VCC，D0，D1，RES，DC和CS第二個分別標為GND，VCC，SCL，SDA，RST，D/C。

七針OLED引腳定義

GND — 接地端口
VCC — 接3.3V電源端口
D0 — CLK時鐘信號(等同于上面的SCL)
D1 — 數據端口(等同于上面的SDA)
RES — 復位端口(等同于上面的RST)
DC — 數據/命令選擇引腳(等同于上面的D/C)
CS — 片選引腳(低電平有效，也就是所需要接低電平，我實際試驗過不接該引腳也是可以正常使用的)

六針OLED引腳定義

GND — 接地端口
VCC — 接3.3V電源端口
SCL — CLK時鐘信號端口
SDA — MOSI數據端口
RST — 復位端口
D/C — 數據/命令選擇引腳

使用

按需修改引腳

oled.h中的OLED_BUFFER_MODE為0時為普通模式，RAM占用少

oled.h中的OLED_BUFFER_MODE為1時使用大小為1024的RAM作為顯存，并使用連續寫入的方法更新屏幕。

main.c

#include "./Drivers/config.h" #include "./Drivers/delay.h"#include "./Drivers/GPIO.h" #include "./SPI_OLED/oled.h"void GPIO_config(void) {GPIO_InitTypeDef GPIO_InitStructure; //結構定義GPIO_InitStructure.Mode = GPIO_OUT_PP; //指定IO的輸入或輸出方式,GPIO_PullUp,GPIO_HighZ,GPIO_OUT_OD,GPIO_OUT_PPGPIO_InitStructure.Pin = GPIO_Pin_3 | GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;//指定要初始化的IO, 或操作GPIO_Inilize(GPIO_P2,&GPIO_InitStructure); //初始化為推挽輸出 }void main(void) {uint8_t i;GPIO_config();OLED_Init();OLED_Clear();OLED_Display_On(); OLED_ShowString(0, 0, "STC15W4K58 OLED", 16, 0);OLED_ShowString(0, 2, " 2022-01-10", 6, 0);for(i = 0; i < 7; ++i)OLED_ShowChinese(8 + 16 * i, 6, i, 1);OLED_Refresh_Gram();while(1){} }
