STM32F103连接到HTS221传感器没有得到正确的温度和湿度值

问答对人有帮助，内容完整，我也想知道答案 0 你好，我试图将我的STM32F103连接到HTS221传感器，但我没有得到正确的温度和湿度值。 HTS221_Driver.c从07/04/2014开始的1.0.0版本到目前为止我做了什么：我错过了什么吗？请帮助我，我检查了很多代码示例，但大多数只处理I2C。 Thx提前！亚历山大＃hts221＃stm32f10x 以上来自于谷歌翻译以下为原文 Hello, i tried to connect my STM32F103 to a HTS221 sensor, but I do not get correct values for temperature and humidity. HTS221_Driver.c has version 1.0.0 from 07/04/2014 What I did so far: 01. ... 02. HTS221_Set_PowerDownMode(HTS221_SET); // Tried with HTS221_RESET as well 03. ... // Do other stuff for ~10ms 04. uint8_t deviceId; 05. HTS221_Get_DeviceID(&deviceId); // successfully returns 0xbc 06. HTS221_StartOneShotMeasurement(); 07. HTS221_BitStatus_et humidityStatus = HTS221_RESET, temperatureStatus = HTS221_RESET; 08. while (temperatureStatus == HTS221_RESET) { 09. HTS221_Get_DataStatus(&humidityStatus, &temperatureStatus); 10. } 11. HTS221_Get_Temperature(&tempTemperature); 12. while (humidityStatus == HTS221_RESET) { 13. HTS221_Get_DataStatus(&humidityStatus, &temperatureStatus); 14. } 15. HTS221_Get_Humidity(&tempHumidity); 16. HTS221_DeActivate(); 17. humidity = ((float) tempHumidity / 10); // Result is 100% 18. temperature = ((float) tempTemperature / 10); // Result is 127�C Did I missed anything? Please help me, I checked a lot of code samples but most of them deal with I2C only. Thx in advance! Alexander #hts221 #stm32f10x 0

答案对人有帮助，有参考价值 0 嗨，您可以尝试在HTS221_Set_PowerDownMode指令后读取CTRL_REG1（0x20h）吗？什么是读取值？请记住，驱动程序中的HTS221_ReadReg和HTS221_WriteReg指令必须使用SPI重新映射，而HTS221 SPI则需要3线。您是否检查过设备是否正确读取和写入SPI级别？问候安东内拉以上来自于谷歌翻译以下为原文 Hi, Can you try to read the CTRL_REG1 (0x20h) after the HTS221_Set_PowerDownMode instruction? What is the read value? Keep in mind that HTS221_ReadReg and HTS221_WriteReg instructions in the driver, have to be remapped with functions using SPI and that for HTS221 SPI is 3 wires. Do you have check that the device is correctly read and written at level of SPI? Regards Antonella
