第一步:先配置好引脚(iiic驱动)或者(spi驱动)
上面这个变量,用来选择 用 iic 还是spi
cpp
/******************** IO配置函数 **************************/
void GPIO_config(void)
{
////准双向口 用来当做led闪烁用
P3_MODE_IO_PU(GPIO_Pin_1);
if( oled_is_spi_mode==0 )//选择iic 驱动 oled
{
// 1. 先配置 GPIO 为开漏输出（OD）+ 内部上拉 iic使用 oled屏幕iic用
P1_MODE_OUT_OD( GPIO_Pin_4 | GPIO_Pin_5 ) // P1.5(SDA), P1.4(SCL)
}else //选择spi 驱动 oled
{
////准双向口
P5_MODE_IO_PU(GPIO_Pin_4); //片选cs
////准双向口
//P1^6;//复位
//P1^7;//数据/命令控制
//P1^3;//MOSI 数据输出
//P1^5;//时钟
P1_MODE_IO_PU( GPIO_Pin_3 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7 );
}
//p32是 //高阻输入 因为p32是外部引脚中断0口,有上升下降沿都中断功能. 只有p32和p33有, 别的外部中断只有下降沿中断
P3_MODE_IN_HIZ(GPIO_Pin_2);
}第二步:初始化 iic 和 spi (时钟速度都不要太快了,SPI超过10M不稳定. iic的话慢很多)
cpp
/**************** I2C初始化函数 *****************/
void I2C_config(void)
{
I2C_InitTypeDef I2C_InitStructure;
I2C_InitStructure.I2C_Mode = I2C_Mode_Master; //主从选择 I2C_Mode_Master, I2C_Mode_Slave
I2C_InitStructure.I2C_Enable = ENABLE; //I2C功能使能, ENABLE, DISABLE
I2C_InitStructure.I2C_MS_WDTA = DISABLE; //主机使能自动发送, ENABLE, DISABLE
I2C_InitStructure.I2C_Speed = 0; //总线速度=Fosc/2/(Speed*2+4), 0~63
I2C_Init(&I2C_InitStructure);
//NVIC_I2C_Init(I2C_Mode_Master,DISABLE,Priority_0); //主从模式, I2C_Mode_Master, I2C_Mode_Slave; 中断使能, ENABLE/DISABLE; 优先级(低到高) Priority_0,Priority_1,Priority_2,Priority_3
I2C_SW(I2C_P14_P15); //I2C_P14_P15,I2C_P24_P25,I2C_P33_P32
// 5. 延时等待稳定
delay_ms(100);
}
/**************** SPI初始化函数 *****************/
void SPI_config(void)
{
SPI_InitTypeDef SPI_InitStructure;
SPI_InitStructure.SPI_Enable = ENABLE; //SPI启动 ENABLE, DISABLE
SPI_InitStructure.SPI_SSIG = ENABLE; //片选位 ENABLE, DISABLE
SPI_InitStructure.SPI_FirstBit = SPI_MSB; //移位方向 SPI_MSB, SPI_LSB
SPI_InitStructure.SPI_Mode = SPI_Mode_Master; //主从选择 SPI_Mode_Master, SPI_Mode_Slave
SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low; //时钟相位 SPI_CPOL_High, SPI_CPOL_Low
SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge; //数据边沿 SPI_CPHA_1Edge, SPI_CPHA_2Edge
SPI_InitStructure.SPI_Speed = SPI_Speed_4; //SPI速度 SPI_Speed_4,SPI_Speed_16,SPI_Speed_64,SPI_Speed_2/SPI_Speed_32
SPI_Init(&SPI_InitStructure);
NVIC_SPI_Init(ENABLE,Priority_3); //中断使能, ENABLE/DISABLE; 优先级(低到高) Priority_0,Priority_1,Priority_2,Priority_3
SPI_SW(SPI_P12_P13_P14_P15); //SPI_P12_P13_P14_P15,SPI_P22_P23_P24_P25,SPI_P54_P40_P41_P43,SPI_P35_P34_P33_P32
//SPI_SS = 1;
}第三步:导入oled的库函数
, 下面这段代码保存为 oled.c
cpp
#include "STC8G_H_I2C.h"
#include "oled.h"
#include "oledfont.h"
#include <string.h> // 需要包含头文件
#include "STC8G_H_SPI.h"
#include "STC8G_H_Delay.h"
//选择是否用spi 还是 iic 驱动
u8 xdata oled_is_spi_mode = 1; // false=I2C, true=SPI（xdata 表示存储在外部RAM）
//u16 FONT_DATA_size = FONT_DATA_SIZE;

第五步 : SPI --DMA的开启方式(dma一次最多只能发256字节这款单片机性能限制 stc32g就不会)
这是我整个工程的文件列表
cpp
void SPI_DMA_Config(void)
{
// typedef struct
//{
// u8 DMA_Enable; //DMA使能 ENABLE,DISABLE
// u8 DMA_Tx_Enable; //DMA发送数据使能 ENABLE,DISABLE
// u8 DMA_Rx_Enable; //DMA接收数据使能 ENABLE,DISABLE
// u16 DMA_Rx_Buffer; //接收数据存储地址
// u16 DMA_Tx_Buffer; //发送数据存储地址
// u8 DMA_Length; //DMA传输总字节数 (0~255) + 1, 不要超过芯片 xdata 空间上限
// u8 DMA_AUTO_SS; //自动控制SS脚使能 ENABLE,DISABLE
// u8 DMA_SS_Sel; //自动控制SS脚选择 SPI_SS_P12,SPI_SS_P22,SPI_SS_P74,SPI_SS_P35
//} DMA_SPI_InitTypeDef;
DMA_SPI_InitTypeDef DMA_SPI_InitStructure;//结构定义
DMA_SPI_InitStructure.DMA_Enable = ENABLE ; //DMA使能 ENABLE,DISABLE
DMA_SPI_InitStructure.DMA_Tx_Enable = ENABLE; //DMA发送数据使能 ENABLE,DISABLE
DMA_SPI_InitStructure.DMA_Rx_Enable = DISABLE; //DMA接收数据使能 ENABLE,DISABLE
//DMA_SPI_InitStructure.DMA_Rx_Buffer; //接收数据存储地址
DMA_SPI_InitStructure.DMA_Tx_Buffer = (u16)(unsigned int)&IMG_DATA[0]; // 安全转换 //发送数据存储地址
DMA_SPI_InitStructure.DMA_Length = 255; //DMA传输总字节数 (0~255) + 1, 不要超过芯片 xdata 空间上限
DMA_SPI_InitStructure.DMA_AUTO_SS = DISABLE; //自动控制SS脚使能 ENABLE,DISABLE
//DMA_SPI_InitStructure.DMA_SS_Sel; //自动控制SS脚选择 SPI_SS_P12,SPI_SS_P22,SPI_SS_P74,SPI_SS_P35
DMA_SPI_Inilize(&DMA_SPI_InitStructure);
NVIC_DMA_SPI_Init( ENABLE , Priority_0 , Priority_0 );//开启传输完毕中断
}调用触发dma发送函数
dma发送结束之后,到dma中断里面(我这个中断里面是为了显示图片所以一直触发)(屏幕要设置成水平寻址模式 )
cpp
//========================================================================
// 函数: DMA_ISR_Handler
// 描述: DMA中断函数.
// 参数: none.
// 返回: none.
// 版本: V1.0, 2021-05-25
//========================================================================
void DMA_ISR_Handler (void) interrupt 13
{
// TODO: 在此处添加用户代码
//----------- DMA ADC --------------
if(DMA_ADC_STA & 0x01) //AD转换完成
{
DMA_ADC_STA &= ~0x01; //清标志位
DmaADCFlag = 1;
}
if (DMA_SPI_STA & 0x01) //检测到spi-dma发送完成中断
{
DmaSPIFlag = 1;//标志位
DMA_SPI_STA &= ~0x01;//手动清零中断标志位
//=====================下面是继续=============================
// 1. 更新地址（每次发送 256 字节）
IMG_DATA_addr += 256;
// 2. 地址回绕（1024 字节循环）
if (IMG_DATA_addr >= 1024) {
IMG_DATA_addr = 0;
}
//dma要发送的数据的首地址变一下 这个地址只能定义在xdata空间里面
DMA_SPI_TXAH = ((u16)(unsigned int)&IMG_DATA[IMG_DATA_addr])>>8;
DMA_SPI_TXAL = (u8)(((u16)(unsigned int)&IMG_DATA[IMG_DATA_addr]));
DMA_SPI_TRIG_M();//dma spi发送
}
}
最后关于DMA在这块屏幕的使用, (不好用)
原因一 : 水平寻址模式 ,无法定位显示位置,中途干扰了显示就全乱了
原因而:这个单片机最多发256字节
