[tocm] 下面是我的作品温湿度计显示。主要使用HPM5300开发板,加上温湿度传感器SHTC3和oled显示。实物如下: ![screenshot_dbb6957e0970b6e504b8ebdacd57540.jpg](https://oss-club.rt-thread.org/uploads/20240916/eb9dcfa8f77f2bc76785be6051345ebf.jpg.webp) ## 主要功能: 这次设计比较简单,主要是读取温湿度传感器并显示。使用硬件平台是先楫的HPM5300-evk开发板,温湿度传感器SHTC3,SSD1306驱动OLED显示。使用I2C0接口接温湿度传感器和OLED显示屏。传感器和oled屏单独做了一块小板,板上还有光照传感器和加速度传感器还未用上。传感器都简单对接了RT-Thread的sensor传感器框架,可以通过传感器设备读取数据。 整个代码在vscode开发,使用env编译,使用先楫的HPMicro_Manufacturing_Tool工具下载固件。所有应用代码在applications文件夹。 ![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20240917/1f56d86d474603632d973005a72b78b5.png.webp) ### 应用软件流程: 在main中启动一个应用线程用于读取传感器数据并显示在OLED屏。 main线程 ```c void thread_entry(void *arg); int main(void) { static uint32_t app_thread_arg = 0; rt_thread_t led_thread = rt_thread_create("app_thread", thread_entry, &app_thread_arg, 1024, 1, 10); rt_thread_startup(led_thread); rt_pin_mode(APP_LED0_PIN_NUM, PIN_MODE_OUTPUT); while(1) { rt_pin_write(APP_LED0_PIN_NUM, APP_LED_ON); rt_thread_mdelay(500); rt_pin_write(APP_LED0_PIN_NUM, APP_LED_OFF); rt_thread_mdelay(100); } return 0; } ``` ### 应用线程: ```c void thread_entry(void *arg) { rt_device_t dev_temp = RT_NULL; rt_device_t dev_humi = RT_NULL; struct rt_sensor_data data; rt_uint8_t buff[16]; int temp,humi; int ground_pos; int i,j; ground_pos = 0; shtc3_port(); rpr0521_port(); adxl345_port(); rt_kprintf("ssd1306 %#x.\r\n",lcd_display_init(&oled_ssd1306)); lcd_set_font_window(0,0,lcd_get_width(),lcd_get_height()); lcd_clear(LCD_WHITE); lcd_display_flush(&oled_ssd1306); rt_thread_mdelay(100); lcd_clear(LCD_BLACK); lcd_set_font(&Font_ASCII16X8_default); lcd_disp_str_at(0,2,"RT-Thread"); lcd_disp_str_at(0,20,"HPM5300"); lcd_disp_str_at(0,40,"WoodData"); oled_qrcode(74, 5, "RT-Thread桌面温湿度计"); rt_thread_mdelay(3000); dev_temp = rt_device_find("temp_shtc3"); if (dev_temp == RT_NULL) { LOG_E("Can't find device:temp_shtc3"); }else { if (rt_device_open(dev_temp, RT_DEVICE_FLAG_RDONLY) != RT_EOK) { LOG_E("open temp_shtc3 device failed!"); }else rt_device_control(dev_temp, RT_SENSOR_CTRL_SET_ODR, (void *)100); } dev_humi = rt_device_find("humi_shtc3"); if (dev_humi == RT_NULL) { LOG_E("Can't find device:humi_shtc3"); }else { if (rt_device_open(dev_humi, RT_DEVICE_FLAG_RDONLY) != RT_EOK) { LOG_E("open humi_shtc3 device failed!"); }else rt_device_control(dev_humi, RT_SENSOR_CTRL_SET_ODR, (void *)100); } lcd_clear(LCD_BLACK); lcd_draw_image(0,0,24,24,(uint8_t*)temperature_code); lcd_draw_image(0,26,24,24,(uint8_t*)humidity_code); while(1) { if ((dev_temp != RT_NULL) && (rt_device_read(dev_temp, 0, &data, 1) != 1)) { LOG_E("read data failed!"); }else { temp = data.data.temp; } rt_thread_mdelay(10); if ((dev_humi != RT_NULL) && (rt_device_read(dev_humi, 0, &data, 1) != 1)) { LOG_E("read data failed!"); }else { humi = data.data.humi; } lcd_set_font(&Font_ASCII_Num12x20); rt_snprintf(buff,10,"%3d.%d\xA1\xE6",temp/10,temp%10); lcd_disp_str_at(32,2,buff); rt_snprintf(buff,10,"%3d.%d%% ",humi/10,humi%10); lcd_disp_str_at(32,28,buff); lcd_display_flush(&oled_ssd1306); for(j=0;j<40;j++) { for(i=0;i<10;i++) { lcd_draw_image(i*16 - ground_pos,56,16,8,(uint8_t *)Ground_n); } lcd_draw_image(20,46,16,16,(uint8_t *)dino16x16); lcd_display_flush(&oled_ssd1306); ground_pos += 4; if(ground_pos >= 16) ground_pos = 0; rt_thread_mdelay(50); } } } ``` i2c接口封装了rt-thread的I2C发送接收函数API。方便各种I2C接口芯片驱动。 ```c uint8_t I2C_WriteByte(void *i2cbus,uint32_t dev_addr, uint32_t addr,uint8_t Byte); uint8_t I2C_ReadByte (void *i2cbus,uint32_t dev_addr, uint32_t addr); uint8_t I2C_PageWrite(void *i2cbus,uint32_t dev_addr, uint32_t addr,uint8_t *str,uint32_t num); uint8_t I2C_PageRead (void *i2cbus,uint32_t dev_addr, uint32_t addr,uint8_t *str,uint32_t num); uint8_t I2C_Write(void *i2cbus,uint32_t dev_addr, uint8_t *cmd,uint32_t len,uint8_t *str,uint32_t num); uint8_t I2C_Read (void *i2cbus,uint32_t dev_addr, uint8_t *cmd,uint32_t len,uint8_t *str,uint32_t num); uint8_t I2C_WriteOnly(void *i2cbus,uint32_t dev_addr,uint8_t *str,uint32_t num); uint8_t I2C_ReadOnly (void *i2cbus,uint32_t dev_addr,uint8_t *str,uint32_t num); uint8_t I2C_IsDeviceReady(void *i2cbus,uint32_t dev_addr); void * I2C_FindDevice(char *name); ``` 温湿度传感器对接sensor框架接口。 ```c #define DBG_ENABLE #define DBG_LEVEL DBG_INFO #define DBG_SECTION_NAME "sensor.sr.shtc3" #define DBG_COLOR #include
