CC2540串口输出调试功能
可以用printf()做串口打印输出
这个功能非常简单，首先在工程管理下的preprocessor把串口打开HAL_UART=TRUE。
然后看我的npi.c文件，多了什么自己琢磨，懒点的就直接复制吧：

Description: This file contains the Network Processor Interface (NPI),
which abstracts the physical link between the Application
Processor (AP) and the Network Processor (NP). The NPI
serves as the HAL's client for the SPI and UART drivers, and
provides API and callback services for its client.

再再然后hal_driver.c下修改：
void HalDriverInit (void)函数下的：
/* UART */ #if (defined HAL_UART) && (HAL_UART == TRUE) HalUARTInit(); NPI_InitTransport(NIP_input); #endif
大功告成！！！！
