Hi,I was able to read ISO/IEC 14443-3 Type A tag using tag_hunting function from sample code. Recently I found tag detection may help to bypass polling stage and interrupt the Host MCU if there is tag nearby. // Calibration command [07 0E 03 A2 00 F8...

I did the temperature test and get the below graph. The Axis data always jumps at some temperature between 10-30 ℃.Settings: 2g scale, high resolution mode and ODR is 100Hz.Did anyone else have encounter such problem? The sensitivity stated on data...

Hi,My calibration process follows the sample code and datasheet . It always returns 0x64 as DacDataRef:// calibration command sent >>> 07 0E 03 A1 00 F8 01 18 00 00 60 60 00 xx 3F 01The result for each step is:Step| xx | <Data>----------------..S0 |...

Hi,HW setupit is custom board and it was able to read ISO14443A Type A tag in tag hunting functionSW setupI use custom SPI driver and Host MCU could communicate with ST95HFI followed the calibration process and could get DacDataH correctly base on d...

The testing process is listed below:We set the sensor to temperature mode in room temperature, and put into oven and heat to more than 70°C In the code, it will enter recording mode after the sensor temperature reaches 63 °CAfter all testing samples...
