基于nRF24L01模块的GPS定位数据传输与显示

1. GPS位置传输

GPS位置信息通过连接到ESP8266或ESP32开发板的nRF24L01收发模块进行传输。nRF24L01模块采用SPI（Serial Peripheral Interface）通信，其引脚连接如下：
| Component | Transmitting nRF24L01 | Transmitting or Receiving nRF24L01 |
| — | — | — |
| nRF24L01 VCC | ESP8266 3V3 | ESP32 3V3 |
| nRF24L01 CSN | ESP8266 D8 | ESP32 GPIO 4 |
| nRF24L01 MOSI | ESP8266 D7 | ESP32 GPIO 23 |
| nRF24L01 IRQ | Not connected | Not connected |
| nRF24L01 GND | ESP8266 GND | ESP32 GND |
