Sensor Demo ============ The sensor demo can be used to read the values of all sensors and print them every 5 seconds on the terminal. In order to use this example the X-NUCLEO-IKS01A1 expansion board featuring ST environmental and motion MEMS sensors must be used. It needs to be connected on top of the NUCLEO-L152RE (MCU) and the X-NUCLEO-IDS01Ax (sub-1GHz RF communication) boards. To build the example type: make TARGET=stm32nucleo-spirit1 USE_SUBGHZ_BOARD=IDS01A4 USE_SENSOR_BOARD=1 or make TARGET=stm32nucleo-spirit1 USE_SUBGHZ_BOARD=IDS01A5 USE_SENSOR_BOARD=1 depending on the sub GHz board you have.
