一、實(shí)現(xiàn)串口

1.1、CC2541的串口簡(jiǎn)介

??CC2541有21個(gè)數(shù)字輸入/輸出引腳， 可以配置為通用數(shù)字I/O或外設(shè)I/O信號(hào)， 配置為連接到ADC、 定時(shí)器或 USART外設(shè)。這些 I/O 口的用途可以通過(guò)一系列寄存器配置，由用戶軟件加以實(shí)現(xiàn)。
??對(duì)于 USART 和定時(shí)器 I/O，在一個(gè)數(shù)字 I/O 引腳上選擇外設(shè) I/O 功能，需要設(shè)置對(duì)應(yīng)的 PxSEL 位為 1。
??外設(shè) I/O 引腳映射如下圖所示：

1.2、CC2541串口的寄存器實(shí)現(xiàn)方法

??對(duì)于每個(gè) USART，有 5 個(gè)如下的寄存器（x 是 USART 的編號(hào)，為 0 或者1）：
??● UxCSR： USARTx 控制和狀態(tài)；
??● UxUCR： USARTx UART 控制；
??● UxGCR： USARTx 通用控制
??● UxBUF： USART x 接收/發(fā)送數(shù)據(jù)緩沖
??● UxBAUD： USART x 波特率控

??CC2541 配置串口的一般步驟：
??1、 配置 IO，使用外部設(shè)備功能。
??2、 配置相應(yīng)串口的控制和狀態(tài)寄存器。
??3、 配置串口工作的波特率。
??具體代碼如下：

#include <ioCC2540.h> #include <string.h> #include "uart.h" /* 串口0，應(yīng)用的IO口為：RX P0.2 TX P0.3 */ #define Uart0_SIZE 40 int8 Rx_Flag0=0; uint8 Rx_length0=0; uint8 RxData0[Uart0_SIZE]; //存儲(chǔ)接收字符串/**************************************************************************** * 名 稱: InitUart() * 功 能: 串口初始化函數(shù) * 入口參數(shù): 無(wú) * 出口參數(shù): 無(wú) ****************************************************************************/ void Uart0_Init(void) { PERCFG &= ~0x01; //外設(shè)控制寄存器 USART 0的IO位置:0為P0口位置1 P0SEL = 0x0c; //P0_2,P0_3用作串口（外設(shè)功能）P2DIR &= ~0xC0; //P0優(yōu)先作為UART0U0CSR |= 0x80; //設(shè)置為UART方式U0GCR |= 11; U0BAUD |= 216; //波特率設(shè)為115200UTX0IF = 0; //UART0 TX中斷標(biāo)志初始置位0U0CSR |= 0x40; //允許接收 IEN0 |= 0x84; //開(kāi)總中斷允許接收中斷 }/**************************************************************************** * 名 稱: UartSendString() * 功 能: 串口發(fā)送函數(shù) * 入口參數(shù): Data:發(fā)送緩沖區(qū) len:發(fā)送長(zhǎng)度 * 出口參數(shù): 無(wú) ****************************************************************************/ void Uart0_Send(uint8 *Data, uint8 len) {uint8 i;U0CSR &= ~0x40; //禁止接收 for(i=0; i<len; i++){U0DBUF = *Data++;while(UTX0IF == 0);UTX0IF = 0;}U0CSR |= 0x40; //允許接收 }/**************************************************************************** * 名 稱: UART0_ISR(void) 串口中斷處理函數(shù) * 描 述: 當(dāng)串口0產(chǎn)生接收中斷，將收到的數(shù)據(jù)保存在RxBuf中 ****************************************************************************/ uint8 ptrdata=0;#pragma vector = URX0_VECTOR __interrupt void UART0_ISR(void) { URX0IF = 0; // 清中斷標(biāo)志 ptrdata=U0DBUF;if(ptrdata!=0x00)/* 因?yàn)楣こ烫厥庑?#xff0c;過(guò)濾掉0X00 */{if(Rx_length0<Uart0_SIZE)RxData0[Rx_length0] = ptrdata; Rx_length0++;}}uint8 Uart0_Read(uint8 *Data) {if(Rx_length0==0)//接收數(shù)據(jù)bit為零{return 0;}else{if(Rx_Flag0==0)//接收數(shù)據(jù)長(zhǎng)度為零，（此時(shí)正在接收數(shù)據(jù)）{Rx_Flag0=Rx_length0;return 0;}else{if(Rx_Flag0!=Rx_length0)//接收長(zhǎng)度數(shù)據(jù)有變化，認(rèn)為數(shù)據(jù)接收沒(méi)有收完{Rx_Flag0=Rx_length0;return 0;}else//接收數(shù)據(jù)長(zhǎng)度在一個(gè)隔離周期（10ms）后沒(méi)有變化，認(rèn)為接收完成{uint8 length=Rx_Flag0;for(uint8 i=0;i<Rx_Flag0;i++){Data[i]=RxData0[i];}Rx_length0=0;Rx_Flag0=0;return length;}}} }

1.3、串口的API實(shí)現(xiàn)方法

1.3.1、IAR 設(shè)置中添加宏定義

??HAL_UART=TRUE

1.3.2初始化串口

??在npi.c的庫(kù)文件中有串口初始化函數(shù)如下：

/******************************************************************************** @fn NPI_InitTransport** @brief This routine initializes the transport layer and opens the port* of the device. Note that based on project defines, either the* UART, USB (CDC), or SPI driver can be used.** input parameters** @param npiCback - User callback function when data is available.** output parameters** @param None.** @return None.*/ void NPI_InitTransport( npiCBack_t npiCBack ) {halUARTCfg_t uartConfig;// configure UARTuartConfig.configured = TRUE;uartConfig.baudRate = NPI_UART_BR;uartConfig.flowControl = NPI_UART_FC;uartConfig.flowControlThreshold = NPI_UART_FC_THRESHOLD;uartConfig.rx.maxBufSize = NPI_UART_RX_BUF_SIZE;uartConfig.tx.maxBufSize = NPI_UART_TX_BUF_SIZE;uartConfig.idleTimeout = NPI_UART_IDLE_TIMEOUT;uartConfig.intEnable = NPI_UART_INT_ENABLE;uartConfig.callBackFunc = (halUARTCBack_t)npiCBack;// start UART// Note: Assumes no issue opening UART port.(void)HalUARTOpen( NPI_UART_PORT, &uartConfig );return; }

為了適應(yīng)工程需求，可修改如下：

void My_NPI_InitTransport( npiCBack_t npiCBack, uint8 baudrate, uint8 parity, uint8 stopbit) {halUARTCfg_t uartConfig;// configure UARTuartConfig.configured = TRUE;uartConfig.baudRate = baudrate;//NPI_UART_BR;uartConfig.parity = parity;uartConfig.stopbit = stopbit;uartConfig.flowControl = NPI_UART_FC;uartConfig.flowControlThreshold = NPI_UART_FC_THRESHOLD;uartConfig.rx.maxBufSize = NPI_UART_RX_BUF_SIZE;uartConfig.tx.maxBufSize = NPI_UART_TX_BUF_SIZE;uartConfig.idleTimeout = NPI_UART_IDLE_TIMEOUT;uartConfig.intEnable = NPI_UART_INT_ENABLE;uartConfig.callBackFunc = (halUARTCBack_t)npiCBack;// start UART// Note: Assumes no issue opening UART port.(void)HalUARTOpen( NPI_UART_PORT, &uartConfig );return; }

1.3.3、定義串口回調(diào)函數(shù)

??在串口回調(diào)函數(shù)中，可以接收串口數(shù)據(jù)

static void NpiSerialCallback( uint8 port, uint8 events ) {(void)port;//加個(gè) (void)，是未了避免編譯告警，明確告訴緩沖區(qū)不用理會(huì)這個(gè)變量if (events & (HAL_UART_RX_TIMEOUT | HAL_UART_RX_FULL)) //串口有數(shù)據(jù){uint8 numBytes = 0;numBytes = NPI_RxBufLen(); //讀出串口緩沖區(qū)有多少字節(jié)if(numBytes == 0){return;}else{uint8 *buffer = osal_mem_alloc(numBytes);//申請(qǐng)緩沖區(qū) bufferif(buffer){ NPI_ReadTransport(buffer,numBytes);//讀取讀取串口緩沖區(qū)數(shù)據(jù)，釋放串口數(shù)據(jù)/*......// 數(shù)據(jù)處理 //藍(lán)牙串口透?jìng)鲿r(shí)，可以在此處調(diào)用BLE發(fā)送數(shù)據(jù)的方法.......*/osal_mem_free(buffer);//釋放申請(qǐng)的緩沖區(qū)}}} }

1.3.4、串口發(fā)送函數(shù)

??串口發(fā)送函數(shù)在npi.c文件內(nèi)定義：

/******************************************************************************** @fn NPI_WriteTransport** @brief This routine writes data from the buffer to the transport layer.** input parameters** @param buf - Pointer to buffer to write data from.* @param len - Number of bytes to write.** output parameters** @param None.** @return Returns the number of bytes written to transport.*/ uint16 NPI_WriteTransport( uint8 *buf, uint16 len ) {return( HalUARTWrite( NPI_UART_PORT, buf, len ) ); }

二、增加特征值char6

?? 本章節(jié)參考了【BLE】CC2541之添加特征值 要實(shí)現(xiàn)透?jìng)?#xff0c; 我們有個(gè)前提， 就是需要建立連接后，需要對(duì)某個(gè)特征值進(jìn)行寫(xiě)和通知。

??將 16 位的 UUID 拆成 2 個(gè)字節(jié)放到數(shù)組里

2.3、添加 char6 的 的配置屬性

??在simpleGATTprofile.c 文件中增加：

// Simple Profile Characteristic 6 Properties static uint8 simpleProfileChar6Props = GATT_PROP_READ | GATT_PROP_WRITE_NO_RSP | GATT_PROP_NOTIFY;// Characteristic 6 Value static uint8 simpleProfileChar6[SIMPLEPROFILE_CHAR6_LEN] = { 0, 0, 0, 0, 0 }; static uint8 simpleProfileChar6Len = 0;// Simple Profile Characteristic 6 Configuration Each client has its own // instantiation of the Client Characteristic Configuration. Reads of the // Client Characteristic Configuration only shows the configuration for // that client and writes only affect the configuration of that client. static gattCharCfg_t simpleProfileChar6Config[GATT_MAX_NUM_CONN];// Simple Profile Characteristic 6 User Description static uint8 simpleProfileChar6UserDesp[17] = "Characteristic 6\0";

2.4、修改屬性表

3.1、串口接收數(shù)據(jù)并通過(guò)無(wú)線發(fā)送

??在1.3.3章節(jié)定義的串口回調(diào)函數(shù)NpiSerialCallback()中可以接收串口數(shù)據(jù)，此時(shí)可以通過(guò)調(diào)用無(wú)線發(fā)送數(shù)據(jù)的函數(shù)，將數(shù)據(jù)發(fā)送出去。數(shù)據(jù)發(fā)送函數(shù)如下：
