基于串口的VL53L0X激光传感器的代码
时间: 2023-09-08 19:12:09 浏览: 160
下面是基于串口的VL53L0X激光传感器的代码示例,使用Arduino Uno开发板:
```
#include <Wire.h>
#include <VL53L0X.h>
VL53L0X sensor;
void setup()
{
Serial.begin(9600);
Wire.begin();
sensor.init();
sensor.setTimeout(500);
sensor.startContinuous();
}
void loop()
{
uint16_t distance = sensor.readRangeContinuousMillimeters();
Serial.print("Distance(mm): ");
Serial.println(distance);
delay(100);
}
```
首先,需要包含VL53L0X库和Wire库。在`setup()`函数中,初始化串口和Wire库,并对传感器进行初始化设置。`setTimeout()`函数设置传感器的读取超时时间,`startContinuous()`函数开始连续测量。
在`loop()`函数中,使用`readRangeContinuousMillimeters()`函数读取传感器的距离值,将其打印到串口上,并通过`delay()`函数设置一定的延时。

基于串口的VL53L0X激光传感器的代码示例,使用单片机开发板
下面是基于串口的VL53L0X激光传感器的代码示例,使用单片机开发板(以STM32为例):
```c
#include "main.h"
#include <stdio.h>
#include <string.h>
UART_HandleTypeDef huart1;
VL53L0X_Dev_t vl53l0x_dev;

VL53L0X_i2c_init(); //初始化I2C总线
if (VL53L0X_Init(&vl53l0x_dev) == VL53L0X_ERROR_NONE) //初始化VL53L0X传感器
{
printf("VL53L0X sensor initialized successfully!\r\n");
}
else
{
printf("VL53L0X sensor initialization failed!\r\n");
while (1);
}
uint16_t distance;
char uart_buf[30];
while (1)
{
if (VL53L0X_GetDistance(&vl53l0x_dev, &distance) == VL53L0X_ERROR_NONE) //读取距离
{
sprintf(uart_buf, "Distance: %d mm\r\n", distance);
HAL_UART_Transmit(&huart1, (uint8_t*)uart_buf, strlen(uart_buf), 1000); //通过串口输出距离
}
HAL_Delay(1000); //1秒延时
}
}
void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct = {0};
RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
/** Initializes the RCC Oscillators according to the specified parameters
* in the RCC_OscInitTypeDef structure.

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;

if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
{
Error_Handler();
}
/** Initializes the CPU, AHB and APB buses clocks
*/
RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
|RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;

RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)
{
Error_Handler();
}
}
static void MX_USART1_UART_Init(void)
{
huart1.Instance = USART1;
huart1.Init.BaudRate = 115200;
huart1.Init.WordLength = UART_WORDLENGTH_8B;
huart1.Init.StopBits = UART_STOPBITS_1;
huart1.Init.Parity = UART_PARITY_NONE;

if (HAL_UART_Init(&huart1) != HAL_OK)
{
Error_Handler();
}
}
static void MX_GPIO_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOA_CLK_ENABLE();
/*Configure GPIO pin : PA1 */
GPIO_InitStruct.Pin = GPIO_PIN_1;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/*Configure GPIO pin : PA2 */
GPIO_InitStruct.Pin = GPIO_PIN_2;

HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/*Configure GPIO pin Output Level */
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_RESET);
}
```
其中,VL53L0X_Init()函数用于初始化VL53L0X传感器,VL53L0X_GetDistance()函数用于读取距离。此外,通过HAL_UART_Transmit()函数可以将距离信息通过串口输出。
需要注意的是,代码中的串口初始化函数和GPIO初始化函数需要根据实际的开发板和连接方式进行修改。
基于串口模拟IIC总线去控制VL53L0X激光传感器代码示例
以下是基于串口模拟IIC总线去控制VL53L0X激光传感器的代码示例:
```c++
#include <SoftwareSerial.h>
#include <Wire.h>
#define SDA 2
#define SCL 3
SoftwareSerial mySerial(9, 10); // RX, TX
void setup() {
Serial.begin(9600);
mySerial.begin(9600);
Wire.begin(SDA, SCL);
pinMode(SDA, OUTPUT);
pinMode(SCL, OUTPUT);
}
void loop() {
readDistance();
delay(1000);
}
void readDistance() {
byte dataToSend[3] = {0x00, 0x01, 0xE8};
byte dataReceived[2];
mySerial.write(0x29);
mySerial.write(dataToSend, 3);
Wire.beginTransmission(0x29);
Wire.write(dataToSend[0]);
Wire.write(dataToSend[1]);
Wire.write(dataToSend[2]);
Wire.endTransmission();
delay(70);
mySerial.write(0x29);
mySerial.write(0x00);
Wire.requestFrom(0x29, 2);
dataReceived[0] = Wire.read();
dataReceived[1] = Wire.read();
int distance = (dataReceived[0] << 8) | dataReceived[1];
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" mm");
}
```
在代码中,我们首先定义了SDA和SCL引脚的编号。然后在`setup()`函数中初始化串口、IIC总线并设置SDA和SCL引脚为输出模式。在`loop()`函数中调用`readDistance()`函数来读取距离值,并延时1秒。
`readDistance()`函数中,首先定义了要发送给传感器的3个字节的数据,其中第一个字节是命令字节,第二个和第三个字节是用于设置传感器的参数。然后使用串口模拟IIC总线发送数据,并等待70毫秒以便传感器有时间处理数据。接着再次使用串口模拟IIC总线发送命令字节,并使用Wire库从传感器读取2个字节的数据。最后将读取到的2个字节转换为距离值,并打印输出。
