CC2640添加 uart

1、关闭lcd显示

BOARD_DISPLAY_USE_LCD=0
BOARD_DISPLAY_USE_UART=0
BOARD_DISPLAY_USE_UART_ANSI=0

2、添加 驱动接口

 UART.c

 UART.h

3、UART.c添加pritnf接口； UART.h中声明

#include <stdarg.h>  //add
#include "Board.h"   //add

static UART_Handle  uartHandle;   //add
static UART_Params  uartParams;   // add
#define  LOG

bool CbPrintf(const char* format, ...)
{
  if(uartHandle == NULL){
    return false;
  }
  va_list arg;
  va_start(arg,format);
  uint8_t txbuf[100];
  uint16_t len = vsprintf((char*)txbuf, format, arg);

  UART_write(uartHandle, txbuf, len);

  return true;
}

//  add
bool CbLog(const char* format, ...)
{
#ifdef  LOG
  if(uartHandle == NULL){
    return false;
  }
  va_list arg;
  va_start(arg,format);
  uint8_t txbuf[100];
  uint16_t len = vsprintf((char*)txbuf, format, arg);

  UART_write(uartHandle, txbuf, len);
#endif
  return true;
}

bool uart_init(void)
{
  UART_init();
  
  UART_Params_init(&uartParams);
  uartParams.writeDataMode = UART_DATA_BINARY;
  uartParams.readDataMode = UART_DATA_BINARY;
  uartParams.readReturnMode = UART_RETURN_FULL;
  uartParams.readEcho = UART_ECHO_OFF;
  uartParams.baudRate = 115200;

  uartHandle = UART_open(Board_UART0, &uartParams);
  if(uartHandle == NULL){
    return false;
  }
  CbLog("uart init..ok.\n");
  return true;
}

4、 static void SimplePeripheral_init(void)中添加初始化代码

   uart_init(void)

6、修改板级文件

uart = UART_open(Board_UART0, &uartParams);
