关于MINI板和战舰板的CAN通信问题（求原子哥和大神）

pc__小强 · 发表于 2014-3-22 19:48:15

我的是原子哥的mini板，今天自己焊了一个jga1050的芯片和战舰的板子通信。我将战舰的程序移植到了mini板上，和战舰进行CAN通信，可是实验时发现，回环模式都是正常的，但是在正常模式时，不能通信，请问，有没有做过类似实验的高人，告诉我移植时，哪里还要修改（我只改了显示的部分）。
以下是mini板的程序，

#include "led.h"

#include "delay.h"

#include "key.h"

#include "sys.h"

#include "usart.h"

#include "lcd.h"

#include "spi.h"

#include "flash.h"

#include "mmc_sd.h"

#include "ff.h"

#include "integer.h"

#include "diskio.h"

#include "text.h"

#include "24cxx.h"

#include "fontupd.h"

#include "24l01.h"

#include "ds18b20.h"

#include "can.h"

求大神指点呀1
