IDE: Arduino IDE2.2.1
Evaluation board: Nucleo-F303RE, VL6180x-statel
I found the library from the github GitHub - stm32duino/VL6180X: Arduino library to support the VL6180X Time-of-Flight and gesture-detection sensor, and installed it successfully.
I want to measure distance of object and lux, but there is no example of source code about that.
I program it by myself as bellow:
#define VL6180x_DEFAULT_DEVICE_ADDRESS 0x29
#define VL6180x_SINGLE_DEVICE_DRIVER 1
#define DEV_I2C Wire
#define IIC_SCL PB8
#define IIC_SDA PB9
#define LED_blink PA5 //D13
#define GPIO_12 PA6 //D12
// Components.
VL6180X sensor(&DEV_I2C, GPIO_12);
/* Setup ---------------------------------------------------------------------*/
void setup() {
int status;
// Led.
pinMode(LED_blink, OUTPUT);
digitalWrite(LED_blink, LOW);
delay(100);
digitalWrite(LED_blink, HIGH);
// Initialize serial for output.
Serial.begin(9600);
//End of workaround
// Initialize I2C bus.
DEV_I2C.begin();
// Configure VL6180X top component.
sensor.begin();
// Switch off VL6180X top component.
sensor.VL6180x_Off();
Serial.print("Start to test...\n");
sensor.VL6180x_On();
// Initialize VL6180X.
status = sensor.Init();
if(status)
{
Serial.println("Init sensor_vl6180x_top failed...");
}
sensor.StartInterleavedMode();
}
/* Loop ----------------------------------------------------------------------*/
void loop() {
// Read Lux.
uint32_t lux;
sensor.GetLight(&lux);
Serial.print("Lux[lux]= ");
Serial.println(lux);
// Read Range.
uint32_t range;
sensor.GetDistance(&range);
Serial.print("Range[mm]= ");
Serial.println(range);
delay(1000);
}
it compiled and uploaded successful, but the I2C can not start, I make sure the hardware connection is ok.
Can you indicate the issues or provide me example of source code?
Thanks a lot.
