## 描述
|
||||
|
||||
<mark>GPS</mark>是一款集成车载设备级别的中科微北斗导航AT6558的Unit，芯片性能强悍，能获取准确全球位置信息，支持多种卫星导航系统，比如中国的BDS, 美国的GPS, 俄罗斯的GLONASS等，同时接受六个卫星导航系统的GNSS信号，并且实现联合定位、导航和授时。接M5Core的GROVE C口，M5Core通过串口与该unit通讯。其中unit还集成了信号放大芯片MAX2659。
|
||||
|
||||
<mark>GPS</mark>with AT6558 inside which is created and developed by a Chinese Company named Zhongkewei. AT6558 is capable of highly performance,supportting many types of satellite navigation system, such as China BDS , USA GPS, and Russia GLONASS etc. It is capable of receiving GNSS signal from 6 satellite navigation system, and capable of joint location ,navigation,and timing . Therefore the module is able to obtain accurate global location information . You can connect it to M5Core port C with GROVE cable, and develope it with UART communication. Regards to the gps Unit , a signal amplifying chip is integrated inside .
|
||||
|
||||
## 特性
|
||||
|
||||
- 支持多种卫星导航系统，比如中国的BDS, 美国的GPS, 俄罗斯的GLONASS等
|
||||
- AT6558
|
||||
- 15mA超低功耗 (15mA Ultra low power comsume)
|
||||
- 集成射频、基带、flash (integrated radio frequency,base band, flash)
|
||||
- 工作温度：-40~85℃ （working temperature）
|
||||
<!-- - GROVE接口，支持[UiFlow](http://flow.m5stack.com)编程，[Arduino](http://www.arduino.cc)编程 -->
|
||||
- Unit内置两个Lego插件孔，方便与Lego件结合 (With two Lego plugin holes on the Unit, it could be more easier to compatable with Lego mountings )
|
||||
|
||||
## 应用
|
||||
|
||||
- 车载定位(Vehicle location)
|
||||
- 智能执法定位(Intelligent Law enforcement location)

## 例程
|
||||
|
||||
### 1. Arduino IDE
|
||||
|
||||
*例程完整*
|
||||
|
||||
```arduino
|
||||
#include <M5Stack.h>
|
||||
|
||||
/* By default, GPS is connected with M5Core through UART2 */
|
||||
HardwareSerial GPSRaw(2);
|
||||
|
||||
void setup() {
|
||||
M5.begin();
|
||||
GPSRaw.begin(9600);// GPS init
|
||||
Serial.println("hello");
|
||||
termInit();
|
||||
}
|
||||
|
||||
void loop() {
|
||||
// put your main code here, to run repeatedly:
|
||||
if(Serial.available()) {
|
||||
int ch = Serial.read();
|
||||
GPSRaw.write(ch);
|
||||
}
|
||||
if(GPSRaw.available()) {
|
||||
int ch = GPSRaw.read();// read GPS information
|
||||
Serial.write(ch);
|
||||
termPutchar(ch);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
烧录例程`GPSRaw.ino`之后，屏幕和串口显示终端会打印如下类似的信息
