本帖最后由 eew_cT3H5d 于 2024-7-29 14:00 编辑先看效果怎么样： OLED屏幕介绍： OLED，即有机发光二极管OLED（Organic Light-Emitting Diode），又称为有机电激光显示（OrganicElectroluminesence Display, OELD）。因为具备轻薄、省电等特性，因此从2003年开始，这种显示设备在MP3播放器上得到了广泛应用，而对于同属数码类产品的DC 与手机，此前只是在一些展会上展示过采用OLED屏幕的工程样品，还并未走入实际应用的阶段。但OLED屏幕却具备了许多LCD不可比拟的优势，因此它也一直被业内人士所看好。目前常见的OLED模块是0.96英寸的显示屏，价格便宜，引脚少很方便使用，其采用的通讯方式常见为IIC和SPI协议，不过IIC的比较常见一些。瑞萨RA8D1通过IIC总线控制0.96

本帖最后由 eew_cT3H5d 于 2024-7-23 23:58 编辑先看效果： WS2812B-5050是一个集控制电路与发光电路于一体的智能外控LED光源；其外型采用最新的molding封装工艺，将IC与发光芯片封装在一个5050的封装尺寸中，每个元件即为一个像素点；像素点内部包含了智能数字接口数据锁存信号整形放大驱动电路，还包含有高精度的内部振荡器和可编程定电流控制部分，有效保证了像素点光的颜色高度一致。它能显示RGB三原色组合成的颜色显示灯，封装为5050，有四个引脚，分别是VCC、VSS、DIN、DOUT . 它的控制协议非常简单，通过一根信号线就可以进行串行异步信号发送 WS2812的级联控制协议是非常简单的。在串行通讯中使用不同高低电平脉冲表示数据0,1编码。通过发送三组24bit的编码，可以控制三个级联的WS2812灯的颜色。每组24bit对应的GRB编码如下所示。发送颜色顺序为GRB，字节的高位在前 WS2812驱动芯片采用单线归零码的通讯方式，芯片在上电复位以后，DIN端接收从控制器传输过来的数据。首先送过来的24 bit数据被第一个芯片提取后，送到芯片内部的数据锁存器。剩余的数据经过内部整形处理电路整形放大后，通过DO端口开始转发输入给下一个级联的芯片，每经过一个芯片的传输，信号减少24 bit。芯片采用自动整形转发技术，使得该芯片的级联个数不受信号传送的限制，仅仅受限信号传输速度要求。驱动波形逻辑分析仪测试：逻辑分析仪波形显示：瑞萨RA8D1通过SPI总线控制ws2812 第一步：在上一个工程继续添加SPI驱动模块配置SPI通道，通过配置通道3可以直接将SPI引脚P309、P311、P310这样直接通过开发板的引出排针引脚直接接入ws2812 经查询将SPI的配置速度设为7.5M，相关时钟可以为60Mhz或者120Mhz 配置系统时钟，采用内部时钟，相关时钟配置120Mhz 第二步：添加ws2812底层驱动库 ws2812.c文件 /* * ws2812.c * * Created on: 2023年10月31日 * Author: Administrator */ #include <WS2812/ws2812.h> #include "hal_data.h" extern fsp_err_t err ; extern volatile bool g_transfer_complete ; //灯条显存SPI数据缓存 uint8_t gWs2812bDat_SPI[WS2812B_AMOUNT * 24+88] = {0}; //灯条显存 tWs2812bCache_TypeDef gWs2812bDat[WS2812B_AMOUNT] = { //R G B 0XFF, 0X00, 0X00, //0 0X00, 0XFF, 0X00, //1 0X00, 0X00, 0XFF, //2 0X00, 0XFF, 0XFF, //3 0XFF, 0X00, 0XFF, //4 0XFF, 0XFF, 0X00, //5 0XFF, 0XFF, 0XFF, //6 0X00, 0X00, 0X00, //7 }; void WS2812b_Set(uint16_t Ws2b812b_NUM, uint8_t r,uint8_t g,uint8_t b) { uint8_t *pR = &gWs2812bDat_SPI[88+(Ws2b812b_NUM) * 24 + 8]; uint8_t *pG = &gWs2812bDat_SPI[88+(Ws2b812b_NUM) * 24]; uint8_t *pB = &gWs2812bDat_SPI[88+(Ws2b812b_NUM) * 24 + 16]; for(uint8_t i = 0; i < 8; i++) { if(g & 0x80) { *pG = CODE_1; } else { *pG = CODE_0; } if(r & 0x80) { *pR = CODE_1; } else { *pR = CODE_0; } if(b & 0x80) { *pB = CODE_1; } else { *pB = CODE_0; } r <<= 1; g <<= 1; b <<= 1; pR++; pG++; pB++; } } void WS2812B_Task(void) { uint8_t dat = 0; for(int i=0;i<88;i++) { gWs2812bDat_SPI[i]=0; } //将gWs2812bDat数据解析成SPI数据 for(uint8_t iLED = 0; iLED < WS2812B_AMOUNT; iLED++) { WS2812b_Set(iLED, gWs2812bDat[iLED].R, gWs2812bDat[iLED].G, gWs2812bDat[iLED].B); } //总线输出数据 /* Send the reset command */ g_transfer_complete = false; err = R_SCI_B_SPI_Write(&g_sci_spi3_ctrl, gWs2812bDat_SPI, sizeof(gWs2812bDat_SPI), SPI_BIT_WIDTH_8_BITS); assert(FSP_SUCCESS == err); /* Wait for SPI_EVENT_TRANSFER_COMPLETE callback event. */ while ( g_transfer_complete==false) { ; } // //使总线输出低电平 // g_transfer_complete = false; // err = R_SCI_SPI_Write(&g_spi0_ctrl, dat, 1, SPI_BIT_WIDTH_8_BITS); // assert(FSP_SUCCESS == err); // /* Wait for SPI_EVENT_TRANSFER_COMPLETE callback event. */ // while ( g_transfer_complete==false) // { // ; // } //帧信号：一个大于50us的低电平 R_BSP_SoftwareDelay(1, BSP_DELAY_UNITS_MILLISECONDS); } ws2812.h文件 /* * ws2812.h * * Created on: 2023年10月31日 * Author: Administrator */ #ifndef _WS2812_H_ #define _WS2812_H_ #include <stdint.h> // 编码 0 : 11000000 #define CODE_0 0xc0 // 编码 1 : 11111000 #define CODE_1 0xF8 /*ws2812b灯珠数量*/ #define WS2812B_AMOUNT 8 typedef struct { uint8_t R; uint8_t G; uint8_t B; } tWs2812bCache_TypeDef; extern tWs2812bCache_TypeDef gWs2812bDat[WS2812B_AMOUNT]; void WS2812b_Set(uint16_t Ws2b812b_NUM, uint8_t r,uint8_t g,uint8_t b); void WS2812B_Task(void); #endif /* WS2812_H_ */ 这个是主程序运行代码，让ws2812显示不同颜色第三步：进行编译程序第四步：程序运行效果：成功点亮ws2812全彩LED，SPI驱动一次性成功视频演示： [localvideo]872201510cb5894e252e27f17966a875[/localvideo] 参考来源： 1.https://blog.csdn.net/qq_24312945/article/details/134152211 2.https://bbs.eeworld.com.cn/thread-1267092-1-1.html

本帖最后由 eew_cT3H5d 于 2024-7-18 00:11 编辑开发板P303、P300、P112、P905可以作为驱动继电器的I/O 通过FSP配置P303、P300作为普通I/O 通过FSP配置P112作为普通I/O 通过FSP配置P905作为普通I/O FSP配置完成，生成相应代码建立封装库C文件建立封装库H文件在hal_entry()写入相应功能代码 #include "LED/LED.h" /*******************************************************************************************************************//** * main() is generated by the RA Configuration editor and is used to generate threads if an RTOS is used.
