CC2530增加printf输出函数

printf在程序调试中有很大帮助,实时打印log,非常方便。特别是在无线系统调试,实时性很强,并不是单步调试能够做到的。
TICC2530,实现printf步骤:

1.添加log.c文件

#include "OSAL.h"
#include "npi.h"
#include 
#include 
#include "log.h"

#if (defined HAL_UART) && (HAL_UART == TRUE)

static void NpiSerialCallback( uint8 port, uint8 events );

void log_init(void)
{
    // 串口初始化 波特率默认是115200, 形参是回调函数
    NPI_InitTransport(NpiSerialCallback);
}

// 串口回调函数,
static void NpiSerialCallback( uint8 port, uint8 events )
{
    (void)port;//加个 (void),是未了避免编译告警,明确告诉缓冲区不用理会这个变量

    if (events & (HAL_UART_RX_TIMEOUT | HAL_UART_RX_FULL))   //串口有数据
    {
        uint8 numBytes = 0;

        numBytes = NPI_RxBufLen();           //读出串口缓冲区有多少字节

        if(numBytes == 0)
        {
            return;
        }
        else
        {
            //申请缓冲区buffer
            uint8 *buffer = osal_mem_alloc(numBytes);
            if(buffer)
            {
                //读取读取串口缓冲区数据,释放串口数据   
                NPI_ReadTransport(buffer,numBytes);   

                //把收到的数据发送到串口-实现回环 
                NPI_WriteTransport(buffer, numBytes);  

                //释放申请的缓冲区
                osal_mem_free(buffer);
            }
        }
    }
}

#define PRINT_BUF_LEN 20

int SerialPrintf(const char*fmt, ...)
{
    uint32 ulLen;
    va_list ap;
    char *pBuf = (char*)osal_mem_alloc(PRINT_BUF_LEN); // 开辟缓冲区
    va_start(ap, fmt);
    ulLen = vsprintf(pBuf, fmt, ap); // 用虚拟打印函数实现

    va_end(ap);
    HalUARTWrite(HAL_UART_PORT_0, (uint8*)pBuf, ulLen); // 从串口 0 输出
    osal_mem_free(pBuf); // 释放内存空间
    return ulLen;
}
#else
int SerialPrintf(const char*fmt, ...)
{
    return 0;
}
#endif // (defined HAL_UART) && (HAL_UART == TRUE)

2.添加log.h文件


#ifndef LOG_H
#define LOG_H

#ifdef __cplusplus
extern "C"
{
#endif

void log_init(void);
int SerialPrintf(const char*fmt, ...);


#define log SerialPrintf


#ifdef __cplusplus
}
#endif

#endif /* LOG_H */

3.添加程序配置宏

4. 添加程序初始化调用(本例在是在Z-Stack Home 1.2.2a.44539\Projects\zstack\HomeAutomation\SampleLight例程上演示的,所以函数添加在zclSampleLight_Init()中)

#if (defined HAL_UART) && (HAL_UART == TRUE)
  log_init();
  log("[%s] %x\n", __FUNCTION__, 123);
#endif

5.查看输出结果

6.特别说明,由于Z-stack代码中没有添加npi.c和npi.h,所以此两个文件是在TI CC2540 BLE协议栈中copy的,具体代码如下:

9.将上面的npi文件添加到工程,就可以了。
