cc2538在contiki系统的串口数据输…

调试时间两天多，换了六七个版本的contiki，最后还是拿着例子按照减法的方式一步一步减掉然后差不多是成了，现在觉得是Makefile设定的问题了，真的很迷，官方wiki，教程和README一点都没有提及！ 官方的wiki看起来很久没有更新，带来了很大的困扰。 花费了两个一整天都在搞串口传入问题，不解决这个问题后面的shell，ELF和Coffee等一大堆都没有办法实现，官方做的真的有点糟糕。 成功实现串口传入后回传这一功能的文件 主文件：cc2538-demo.c #include "contiki.h" #include "cpu.h" #include "sys/etimer.h" #include "sys/rtimer.h" #include "dev/leds.h" #include "dev/uart.h" #include "dev/cc2538-sensors.h" #include "dev/button-sensor.h" #include "dev/als-sensor.h" #include "dev/watchdog.h" #include "dev/serial-line.h" #include "dev/sys-ctrl.h" #include "net/rime/broadcast.h" #include #include   #define LEDS_PERIODIC       LEDS_RED static struct etimer et; static struct rtimer rt; static uint16_t counter; PROCESS(cc2538_demo_process, "cc2538 demo process"); AUTOSTART_PROCESSES(&cc2538_demo_process); void rt_callback(struct rtimer *t, void *ptr) {   leds_off(LEDS_PERIODIC); } PROCESS_THREAD(cc2538_demo_process, ev, data) {   PROCESS_BEGIN();   while(1) {     PROCESS_YIELD();       if(ev == serial_line_event_message)      {     printf("Data Receive\n");     printf("Receive data is:%s\n",data); } }   PROCESS_END(); } Makefile文件： DEFINES+=PROJECT_CONF_H=\"project-conf.h\" CONTIKI_PROJECT = cc2538-demo timer-test all: $(CONTIKI_PROJECT) CONTIKI = ../../..
