# LORA_WLAN ## 介绍 一个轻量级的Lora无线通信协议，本协议基于SX1278芯片开发。 ## 使用（举例） > Demo可参考 https://gitee.com/huzhicheng666/NJFUWork_Final.git 工程 1. 初始化 - SX1278硬件及Lora WLAN初始化 ```c //SX1278初始化 SX1278_hw_t SX1278_hw;//定义为全局 SX1278_t SX1278;//定义为全局 SX1278_hw.dio0.port = LORA_DIO0_GPIO_Port; SX1278_hw.dio0.pin = LORA_DIO0_Pin; SX1278_hw.nss.port = LORA_NSS_GPIO_Port; SX1278_hw.nss.pin = LORA_NSS_Pin; SX1278_hw.reset.port = LORA_RESET_GPIO_Port; SX1278_hw.reset.pin = LORA_RESET_Pin; SX1278_hw.spi = &hspi1; SX1278.hw = &SX1278_hw; SX1278_H_Init(&SX1278, 413000000, SX1278_POWER_17DBM,SX1278_LORA_SF_7, SX1278_LORA_BW_500KHZ, SX1278_LORA_CR_4_5,SX1278_LORA_CRC_EN, 10); SX1278.Running_Status = SX1278_RUNNING_IDLE; SX1278_H_RX_Once(&SX1278, 50, 200); //Lora WLAN初始化 #if(LORA_WLAN_AFLP == STD_ON && LORA_WLAN == STD_ON) application_layer_init(); #endif #if (LORA_WLAN == STD_ON) data_link_layer_init(); network_layer_init(); #endif ``` - 将network_layer_main_function()放置于周期task或者while(1)中 ```c taskENTER_CRITICAL();//临界区，这里以freertos为例 network_layer_main_function(); taskEXIT_CRITICAL(); ``` 2. 发送 ```c taskENTER_CRITICAL();//临界区，这里以freertos为例 if (get_network_layer_send_state() == sending_idle) { network_layer_data_frame_send(&Tx_Data[0], 10, To_MAC_Address);//(发送的数据Buffer,长度，接收节点MAC地址) } taskEXIT_CRITICAL(); ``` 3. 接收（放置在IO中断回调函数中） ```c if (GPIO_Pin == LORA_DIO0_Pin) { switch (SX1278.Running_Status) { case SX1278_RUNNING_TX_PENDING: SX1278.Running_Status = SX1278_RUNNING_IDLE; SX1278_H_RX_Once(&SX1278, 50, 200);//(SX1278_t *module, uint8_t length, uint32_t timeout) break; case SX1278_RUNNING_RX_PENDING: SX1278.Running_Status = SX1278_RUNNING_RX_DONE; SX1278_H_RX_Once(&SX1278, 50, 200); break; case SX1278_RUNNING_RX_DONE: SX1278_H_RX_Once(&SX1278, 50, 200); default: break; } } ``` ## 功能 > 待更新
