hts221返回0xAE

你好，
 
 
我也在尝试使用HTS221传感器，并一直怀疑固件。我想知道你是否有一个名为HAL_EnvSensors.h的文件以及HTS221固件。如果有的话，请你分享一下这个文件吗？
 
谢谢，

Hello,


I am also trying to work with HTS221 sensor and have been posting doubts about the firmware. I would like to know if you have a file called HAL_EnvSensors.h along with the HTS221 firmware. Can you please share the file, in case you have it?  

Thanks,

交换传感器测试，工作，固定标识符读取正确（188或0xBC）两者的数据表，但寄存器中的数据不更新。尝试了所有选项注册设置。始终是同一个29％的湿度。温度也是固定的。准备就绪将数据准备好的报告记录为温度和湿度。显然是有缺陷的批次。

Exchange with sensor tested, working, fixed identifier read correctly (188 or 0xBC) datasheet for both, but the data in the registers are not updated. Having tried all the options register settings. Always one and the same humidity of 29%. The temperature is also fixed. readiness Register reports that are ready the data as temperature and humidity. Apparently the defective batch.

嗨，
 
 我见过你的代码，我有一些建议和问题：1。在设置AV_CONF（10h）寄存器然后设置CTRL_REG1（20h）寄存器之前，应该更好地改变HTS221_Init的设置顺序。
2.在HTS221_GetHymidity中，我猜有一个错误。
 
 要获得H0_T0_out值，必须读取0x36寄存器而不是0x30; 3。我不清楚你在哪里使用函数HTS221_GetStatus。
 
 在调用HTS221_GetHymidity之前，您是否调用了此功能并检查了湿度数据是否准备就绪？

Hi,

I 've seen your code and I have some suggestions and questions:1. In the HTS221_Init should be better change the order of settings, before set the AV_CONF (10h) register and then the CTRL_REG1 (20h) register.
2. In the HTS221_GetHymidity, I guess there is an mistake.

To get the H0_T0_out value, you have to read the 0x36 register and not 0x30;3. I am not clear where you use the function HTS221_GetStatus.

Did you call this function and checked that the humidity data is ready before to call the HTS221_GetHymidity?Regards
