contiki 开发日记之串口开发

cc2430平台有2个串口uart0（P0_2,P0_3) 和uart1(P0_4,P0_5)

在contiki开发过程中因为牵扯到步骤调试这里有 platform/sensinode-debug.h文件。

里面的putstring即相当于printf在其他编译器中控制台输出功能。

在加入头文件后即可实现printf函数的使用。

其中注意platform/contiki-conf.h头文件。此文件是配置contiki的各种资源。

如果你在使用uart0_init（）会报错的情况下，需要设置里面的资源，如下：

/*
 * UARTs: 1=>Enabled, 0=>Disabled. Default: Both Disabled (see uart.h)
 * Disabling UART0 saves ~200 bytes of CODE.
 * Disabling UART1 saves ~500 bytes of CODE but also disables all debugging
 * output. Should be used when nodes are meant to run on batteries
 *
 * On N740, by enabling UART1, you are also enabling an ugly hack which aims
 * to detect the USB connection during execution. It will then turn on/off
 * UART1 RX interrupts accordingly. This seems to work but you have been warned
 * If you start seeing random crashes when on battery, this is where to look.
