Fermion: I2C H3LIS200DL Triple Axis Accelerometer

1. Example Code for Arduino-Wakeup Function

Use wake-up function. Phenomenon: To use this function, you need to turn the module into low-power mode first, and the measurement rate will be very slow at this time. When an interrupt event set up before occurs, the module will enter normal mode, in which the measurement rate will be accelerated to save power and provide sampling rate. When using SPI, chip select pin can be modified by changing the value of macro H3LIS200DL_CS.

2. Example Code for Arduino-Read Acceleration

Get the acceleration in the three directions of xyz, the range can be ±100g or ±200g. When using SPI, chip select pin can be modified by changing the value of macro H3LIS200DL_CS.

3. Example Code for Arduino-External Interrupt

Interrupt detection. In this example, the enable eZHigherThanTh interrupt event means when the acceleration in the Z direction exceeds the threshold set by the program, the interrupt level can be detected on the interrupt pin int1/int2 we set, and the level change on the interrupt pin can be used to determine whether the interrupt occurs. The following are the 6 settable interrupt events：eXHigherThanTh, eXLowerThanTh, eYHigherThanTh, eYLowerThanTh, eZHigherThanTh, eZLowerThanTh. For a detailed explanation of each of them, please look up the comments of the enableInterruptEvent() function. This example needs to connect the int2/int1 pin of the module to the interrupt pin of the motherboard. Default UNO(2), Mega2560(2), Leonardo(3), microbit(P0),FireBeetle-ESP8266(D6),FireBeetle-ESP32((D6),FireBeetle-M0(6).

4. Example Code for Raspberry Pi-Read Acceleration

Read the acceleration in the three directions of xyz.

5. Example Code for Raspberry Pi-Wakeup Function

Use wake-up function (Only available for Breakout Version).

6. Example Code for Raspberry Pi-External Interrupt

External interrupt function.
