、基于Nucleo-STM32L476L的Arduino实现NUCLEO-IKS01A3的全部传感器驱动实现。 初始计划是采用MKR1000，但是在使用和下载的过程中，这个开发板给变砖了。
所以只好先拿出吃灰的Nucleo-STM32L476L先实现以下基本的arduino驱动。在完成这个基本评测后再移植到其他arduino开发板上使用。
针对不同的传感器，参照以下具体代码逐个说明和实现。
这个过程中首先需要使用开发板管理器安装arduino开发板，
这样就可以设置开发板了，
然后安装NUCLEO-IKS01A3的传感器驱动，
这样就可以再程序中直接使用驱动库了。
驱动和安装说明可以从如下链接获得，https://github.com/stm32duino/Arduino_Core_STM32 这个是官方的arduino驱动。
2、传感器驱动代码和说明 2.1 首先导入HTS221Sensor.h，这个是HTS221的驱动，设定I2C的引脚后就可以直接访问HTS221传感器，程序读取传感器的数据，转换后通过串口输出。 代码如下： - #include <HTS221Sensor.h>
- #define I2C2_SCL PB10
- #define I2C2_SDA PB11
- // Components.
- HTS221Sensor *HumTemp;
- TwoWire *dev_i2c;
- void setup() {
- // Led.
- pinMode(LED_BUILTIN, OUTPUT);
- // Initialize serial for output.
- Serial.begin(9600);
- // Initialize I2C bus.
- dev_i2c = new TwoWire(I2C2_SDA, I2C2_SCL);
- dev_i2c->begin();
- // Initlialize components.
- HumTemp = new HTS221Sensor (dev_i2c);
- HumTemp->Enable();
- }
- void loop() {
- // Led blinking.
- digitalWrite(LED_BUILTIN, HIGH);
- delay(250);
- digitalWrite(LED_BUILTIN, LOW);
- delay(250);
- // Read humidity and temperature.
- float humidity, temperature;
- HumTemp->GetHumidity(&humidity);
- HumTemp->GetTemperature(&temperature);
- // Output data.
- Serial.print("Hum[%]: ");
- Serial.print(humidity, 2);
- Serial.print(" | Temp[C]: ");
- Serial.println(temperature, 2);
- }
输出结果如下，
因为本传感器只检查温度和湿度，所以使用照片显示结果，

- uint32_t previous_tick;
- float temperature = 0;
- STTS751Sensor *Temp;
- void INT1Event_cb()
- {
- mems_event = 1;
- }
- void setup() {
- // Led.

- Temp = new STTS751Sensor(&DEV_I2C);
- Temp->Enable();
- Temp->SetOutputDataRate(4.0f);
- Temp->SetLowTemperatureThreshold(22.0f);
- Temp->SetHighTemperatureThreshold(28.0f);
- Temp->SetEventPin(1);
- Temp->GetTemperatureLimitStatus(NULL, NULL, NULL);
- previous_tick=millis();
- }
- void loop() {
- if (mems_event)
- {
- mems_event=0;
- uint8_t highTemp = 0, lowTemp = 0;
- Temp->GetTemperatureLimitStatus(&highTemp, &lowTemp, NULL);
- if (highTemp){
- high = 1;
- low = 0;
- }
- if (lowTemp){
- low = 1;
- high = 0;
- }
- Temp->GetTemperature(&temperature);
- // Led blinking.
- digitalWrite(LED_BUILTIN, HIGH);
- delay(100);
- digitalWrite(LED_BUILTIN, LOW);
- }
- uint32_t current_tick = millis();
- if ((current_tick - previous_tick) >= 2000){
- if (!high && !low){
- Temp->GetTemperature(&temperature);
- }
- SerialPort.print("Temp[C]: ");
- SerialPort.print(temperature, 2);
- if (high){
- SerialPort.println(" High temperature detected!(>28C) ");
- high = 0;
- } else if (low) {
- SerialPort.println(" Low temperature detected!(<22C) ");
- low = 0;
- } else {
- SerialPort.println();
- }
- previous_tick = millis();
- }
- }
