以下是一个简单的例程,可以帮助你驱动TFLuna激光雷达并使用OLED屏幕显示数据。需要使用STM32F103C8T6开发板和OLED屏幕模块。请注意,本代码仅供参考,你需要自己根据实际情况进行修改和优化。
```c
#include "stm32f10x.h"
#include "usart.h"
#include "oled.h"
#define TFLUNA_UART USART1
void TFLuna_Init(void);
void TFLuna_ReadData(uint8_t* pData, uint16_t size);
void TFLuna_SendCommand(const char* cmd);
int main(void)
{
uint8_t tfluna_data[9];
uint16_t distance = 0;
char oled_str[20];
// 初始化USART1和OLED
USART1_Config();
OLED_Init();
// 初始化TFLuna激光雷达
TFLuna_Init();
while(1)
{
// 读取TFLuna激光雷达数据
TFLuna_ReadData(tfluna_data, 9);
distance = (tfluna_data[3] << 8) | tfluna_data[2];
// 显示距离数据到OLED
sprintf(oled_str, "Distance:%dmm", distance);
OLED_ShowString(0, 0, oled_str);
}
}
void TFLuna_Init(void)
{
// 配置GPIO
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
// 配置USART1
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);
USART_InitStructure.USART_BaudRate = 115200;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init(TFLUNA_UART, &USART_InitStructure);
USART_Cmd(TFLUNA_UART, ENABLE);
}
void TFLuna_ReadData(uint8_t* pData, uint16_t size)
{
uint16_t i;
// 发送读取命令
TFLuna_SendCommand("D");
// 读取数据
for(i = 0; i < size; i++)
{
while(USART_GetFlagStatus(TFLUNA_UART, USART_FLAG_RXNE) == RESET);
pData[i] = USART_ReceiveData(TFLUNA_UART);
}
}
void TFLuna_SendCommand(const char* cmd)
{
while(*cmd)
{
USART_SendData(TFLUNA_UART, *cmd++);
while(USART_GetFlagStatus(TFLUNA_UART, USART_FLAG_TXE) == RESET);
}
}
```
需要注意的是,本例程假设TFLuna激光雷达的通信协议是ASCII码,并且读取距离数据的命令是"D"。如果你的TFLuna激光雷达通信协议不同,或者读取距离数据的命令不同,请修改相应的代码。另外,OLED显示屏模块的接口也需要根据具体情况进行修改。
