2、HAL库SPI在CUBEMX中的配置
2.1 硬件原理图
先来看看LCD 硬件连接方式:
STM32与LCD引脚对应关系:
STM32 | LCD |
---|---|
PA5 | SPI-CLK |
PA4 | SPI_CS |
PA7 | SPI_MOSI |
PA6 | SPI_CS |
PB2 | SPI_RST |
PE7 | LEDK |
2.2 cubemx中配置
LCD是挂在硬件SPI的SPI1上,CS引脚也挂在硬件SPI上,可以直接配置,不用再操心CS引脚的电平转换了,库函数内部自动完成。
配置硬件SPI1,LCD驱动秩序要MOSI即可,只发送数据,不接收
配置非常简单,以上就是全部,直接生成代码即可。
2.3 SPI配置代码解析
2.3.1 寄存器配置:
2.3.2 硬件引脚配置
整个过程虽然一行代码没写,但是配置过程考验的是你对SPI的理解,还是需要掌握,只是说现在有工具把重复的代码平台化了。
2.3.3 SPI接口解析:
关于SPI的接口和串口差不多,也是非常多的,HAL库每个库文件前面都有详细的使用说明,大家如果可以看下这部分:
接口方式基本上和串口差不多,读写、中断读写、DMA、回调函数等,基本上都是一个调性。
本次我们使用的比较简单,LCD只需要写就可以,所以我们只用发送函数即可:
/** *@briefTransmitanamountofdatainblockingmode. *@paramhspipointertoaSPI_HandleTypeDefstructurethatcontains *theconfigurationinformationforSPImodule. *@parampDatapointertodatabuffer *@paramSizeamountofdatatobesent *@paramTimeoutTimeoutduration *@retvalHALstatus */ HAL_StatusTypeDefHAL_SPI_Transmit(SPI_HandleTypeDef*hspi,uint8_t*pData,uint16_tSize,uint32_tTimeout);
3、LCD驱动编写
3.1 SPI LCD写数据/命令
这块板子带的LCD显示屏的驱动是ST7789,分辨率是240*240的,关于LCD就不多做介绍了,大家可以自行百度。
先来封装几个用到的函数,写法都比较初级,大佬轻喷....
LCD复位:
//ST7789复位 staticvoidlcd_st7789_reset(void) { HAL_GPIO_WritePin(LCD_RST_GPIO_Port,LCD_RST_Pin,GPIO_PIN_SET); rt_thread_mdelay(1); HAL_GPIO_WritePin(LCD_RST_GPIO_Port,LCD_RST_Pin,GPIO_PIN_RESET); rt_thread_mdelay(10); HAL_GPIO_WritePin(LCD_RST_GPIO_Port,LCD_RST_Pin,GPIO_PIN_SET); rt_thread_mdelay(120); }
打开LCD背光灯
voidlcd_st7789_power_ctrl(uint8_tenable) { if(enable) HAL_GPIO_WritePin(LCD_POWER_EN_GPIO_Port,LCD_POWER_EN_Pin,GPIO_PIN_SET); else HAL_GPIO_WritePin(LCD_POWER_EN_GPIO_Port,LCD_POWER_EN_Pin,GPIO_PIN_RESET); }
ST7789写数据/命令
//ST7789写函数 staticHAL_StatusTypeDeflcd_st7789_write(intis_cmd,uint8_tdata) { uint8_tpData[2]={0}; assert_param(NULL!=hspi_lcd); pData[0]=data; if(is_cmd) HAL_GPIO_WritePin(LCD_DC_GPIO_Port,LCD_DC_Pin,GPIO_PIN_RESET); else HAL_GPIO_WritePin(LCD_DC_GPIO_Port,LCD_DC_Pin,GPIO_PIN_SET); returnHAL_SPI_Transmit(hspi_lcd,pData,1,HAL_MAX_DELAY); } /******************************************************************** * *LcdWriteReg * *Functiondescription: *Setsdisplayregister */ voidlcd_st7789_write_reg(uint8_tData) { HAL_GPIO_WritePin(LCD_DC_GPIO_Port,LCD_DC_Pin,GPIO_PIN_RESET); HAL_SPI_Transmit(&hspi1,&Data,1,10); } /******************************************************************** * *LcdWriteData * *Functiondescription: *Writesavaluetoadisplayregister */ voidlcd_st7789_write_data(uint8_tData) { HAL_GPIO_WritePin(LCD_DC_GPIO_Port,LCD_DC_Pin,GPIO_PIN_SET); HAL_SPI_Transmit(&hspi1,&Data,1,10); } /******************************************************************** * *lcd_st7789_write_data_multiple * *Functiondescription: *Writesmultiplevaluestoadisplayregister. */ voidlcd_st7789_write_data_multiple(uint8_t*pData,intNumItems) { HAL_GPIO_WritePin(LCD_DC_GPIO_Port,LCD_DC_Pin,GPIO_PIN_SET); HAL_SPI_Transmit(&hspi1,pData,NumItems,10); }
基本的驱动函数就这些,都是SPI写数据或者写命令的函数,具体可以看源码。
3.2 LCD基本驱动函数
让LCD亮起来,实际上就是操作一个个像素点,以下封装了一些基本函数,只放出了函数接口名,具体的可以公众号后台回复“TFT”获取源码:
/** *@brief以一种颜色清空LCD屏 *@paramcolor——清屏颜色(16bit) *@returnnone */ voidlcd_st7789_clear(uint16_tcolor); /** *@brief以一种颜色清填充LCD屏区域 *@paramcolor——清屏颜色(16bit) *@returnnone */ voidlcd_st7789_fill_area(uint16_txs,uint16_tys,uint16_txe,uint16_tye,uint16_tcolor); /** *@brief以一种颜色划横线 *@paramcolor——划线颜色(16bit) *@returnnone */ voidlcd_st7789_draw_x_line(uint16_txs,uint16_tys,uint16_txe,uint16_tye,uint16_tcolor); /** *@brief以一种颜色划竖线 *@paramcolor——划线颜色(16bit) *@returnnone */ voidlcd_st7789_draw_y_line(uint16_txs,uint16_tys,uint16_txe,uint16_tye,uint16_tcolor); /** *@brief以一种颜色划四边形 *@paramcolor——划线颜色(16bit) *@returnnone */ voidlcd_draw_rectangle(uint16_txs,uint16_tys,uint16_txe,uint16_tye,uint16_tcolor); //往指定区域写一个像素 voidlcd_st7789_write_pixel(uint16_tXpos,uint16_tYpos,uint16_tdata); /** *@brief带颜色画任意角度直线,相对长度 *@paramxs起点坐标 *@paramxe终点坐标 *@returnnone */ voidlcd_st778_draw_angle_relative_line(uint16_txs,uint16_tys,floatangle,uint16_tr,uint16_tlens,uint16_tlene,uint16_tcolor); /** *@brief带颜色画任意角度直线,绝对长度 *@param *@param *@returnnone */ voidlcd_st778_draw_angle_absolute_line(uint16_txs,uint16_tys,floatangle,uint16_tlen,uint16_tcolor); /** *@brief带颜色画线函数(直线、斜线) *@paramxs,ys起点坐标 *@paramxe,ye终点坐标 *@returnnone */ voidlcd_st778_draw_colorline(uint16_txs,uint16_tys,uint16_txe,uint16_tye,uint16_tcolor); /** *@breif带颜色画圆函数 *@paramx1,x2——圆心坐标 *@paramr——半径 *@paramcolor——颜色 *@retvalnone */ voidlcd_st7789_color_circle(uint16_tx,uint16_ty,uint16_tr,uint16_tcolor); /** *@brief显示图片函数 *@paramx,y——起点坐标 *@paramwidth——图片宽度 *@paramheight——图片高度 *@paramp——图片缓存数据起始地址 *@returnnone *@noteImage2Lcd取模方式:C语言数据/水平扫描/16位真彩色(RGB565)/高位在前,其他的不选 */ voidlcd_st7789_show_picture(uint16_tx,uint16_ty,uint16_twidth,uint16_theight,constuint8_t*p); /** *@brief显示一个ASCII码字符 *@paramx,y显示起始坐标 *@paramch需要显示的字符 *@paramsize字体大小(支持16/24/32号字体) *@returnnone *@note需要font.h字库文件的支持 */ staticvoidlcd_st7789_show_char(uint16_tx,uint16_ty,uint8_tch,uint16_tback_color,uint16_tfont_color,uint8_tfont_size);
4、实战画表
上面介绍了那么多绘图接口,接下来就来实际画个表来玩玩....说实话,画表挺有意思的....就是很费劲....
