GPS定位程序,ATGM332D模块

非常抱歉,我并不是一个可以运行代码的程序,我是一个自然语言处理的AI,无法直接为你编写代码。不过,我可以提供一些思路和指导,帮助你完成这个任务。
ATGM332d是一款GPS模块,可以通过UART与STM32通信。因此,你需要先在STM32上配置串口通信,然后通过串口读取GPS模块发送的数据。GPS模块发送的数据格式一般为NMEA格式,需要进行解析才能得到经纬度等数据。
以下是一个简单的示例程序,可能需要根据实际情况进行适当修改:
```c
#include "stm32f10x.h"
#define GPS_USART USART1
#define GPS_USART_CLK RCC_APB2Periph_USART1
#define GPS_USART_GPIO_CLK RCC_APB2Periph_GPIOA
#define GPS_USART_TX_PIN GPIO_Pin_9
#define GPS_USART_RX_PIN GPIO_Pin_10
#define GPS_USART_GPIO GPIOA
void GPS_USART_Config(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(GPS_USART_CLK | GPS_USART_GPIO_CLK, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPS_USART_TX_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPS_USART_GPIO, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPS_USART_RX_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPS_USART_GPIO, &GPIO_InitStructure);
USART_InitStructure.USART_BaudRate = 9600;
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(GPS_USART, &USART_InitStructure);
USART_Cmd(GPS_USART, ENABLE);
}
char GPS_USART_ReadByte(void)
{
while (USART_GetFlagStatus(GPS_USART, USART_FLAG_RXNE) == RESET);
return USART_ReceiveData(GPS_USART);
}
void GPS_USART_ReadLine(char* buf, int size)
{
int i = 0;
char c;
while (i < size - 1)
{
c = GPS_USART_ReadByte();
if (c == '\r')
continue;
if (c == '\n')
break;
buf[i++] = c;
}
buf[i] = '\0';
}
int GPS_ParseNMEA(char* line, float* lat, float* lon)
{
char* p = strtok(line, ",");
if (strcmp(p, "$GPGGA") != 0)
return 0;
p = strtok(NULL, ","); // UTC时间
p = strtok(NULL, ","); // 纬度
if (strlen(p) < 9)
return 0;
*lat = atof(p) / 100;
*lat += atof(p + 2) / 60;
p = strtok(NULL, ","); // 纬度方向
if (*p == 'S')
*lat = -*lat;
p = strtok(NULL, ","); // 经度
if (strlen(p) < 10)
return 0;
*lon = atof(p) / 100;
*lon += atof(p + 3) / 60;
p = strtok(NULL, ","); // 经度方向
if (*p == 'W')
*lon = -*lon;
return 1;
}
int main(void)
{
char line[80];
float lat, lon;
GPS_USART_Config();
while (1)
{
GPS_USART_ReadLine(line, sizeof(line));
if (GPS_ParseNMEA(line, &lat, &lon))
{
printf("Latitude: %f, Longitude: %f\r\n", lat, lon);
}
}
}
```
这个程序实现了通过USART1与GPS模块通信,解析GPS模块发送的NMEA格式数据,并输出经纬度信息。需要注意的是,这个程序仅作为示例,实际使用时需要根据具体的硬件环境和需求进行修改。
