SPI is not very different from I2C. To enable a slave device, we need to pull the CS pin low and after our read or write is complete, just pull the pin high again. This will disable the slave device.
DHT11 digital temperature and humidity sensor is a composite Sensor contains a calibrated digital signal output of the temperature and humidity. Today in this tutorial we will be using DHT11 sensor with STM32.
Set the TAP THRESHOLD to 2.5g. To do that we need to write 40 (2.5/.0625) to the THRESH_TAP Register. This means that you need at least 2.5g acceleration in Z AXIS in order for the tap to qualify as TAP.
