Description: 设8359的两端口地址为60H,61H,使用三号中断源,IR3与SP相连。中断方式为边沿触发方式,每按一次AN按钮产生了一次中断信号,向8259A发出中断请求信号。如果中断源电平信号不符合规定要求则转到7号中断,显示“Err”。CPU响应中断后,在中断服务中,对中断次数进行计数并显示,计满5次结束,显示器显示“Good”。-established in 8359 to address two port 60H, 61H, use Route interrupt source, P value will cause connected with the SP. Interrupt trigger for 2500, every time the button AN produce a signal interruption. A 8259 issued to the interrupt request signal. If the interrupt source-level signals do not meet requirements on the 7th was interrupted to show that "Err." CPU interrupt response, after a break in service, the interruption frequency count and showed that the expiration of five times over, The display shows "Good."

Description: 这是一个字母或数制之间的转化程序,5为主模块,调用模块1和模块7
模块1又调用模块2、3、4和6四个模块,其中:
模块2实现小写字母向大写字母的转换
模块3实现大写字母向小写字母的转换
模块4实现二进制数向十六进制数的转换
模块6实现十六进制数向二进制数的转换
模块7实现十六进制数向十进制数的转换
按“q”键退出。
使用时,需将7个文件分别汇编,连接的方法为:
5+1+2+3+4+6+7
生成可执行文件“5” 即可运行。-This a letter or number into the system procedures, five main modules, Call module and a module is a 7 module called Blocks 2, 3, 4 and 6 4 module, which : Module 2 lowercase letters to the realization of capital letters conversion module to achieve three capital letters to lowercase letters conversion module is 4 is the binary number to hexadecimal number of conversion modules to achieve 6 hexadecimal number to the number of binary conversion modules into seven achieve 16 to the metric system for a few number of conversion by the "q" key to exit.

Description: 、 先在microchip网站上找到00738.zip,这个包中有
can18xx8.h,can18xx8.c,将其复制到一个你要编写程度的子目录中,例如C:\testcan下,这个时候这个东东是不能直接用的。
2、 下载一个MPLAB 7.10,直接安装(要求直接下载)
3、 再下载一个PICC18 (HI-TECH的),要正版哦(支持正版,买不起的想其它办法吧)
4、在你的头文件上写上如下的样式:
#include "stdio.h"
#include "can18xx8.h"
#include "pic18fxx8.h"//可能是“pic.h”不太好包含,因此常会报错,直接包含克服之
5、然后设置好PICC和MPLAB,如果MPLAB上没有PICC18,则到PICC的网上下一个安装软件,可以直接运行安装就有了。
6、按照工程的基本要求把你的源代码、添加上两个库(不加也可以)
然后就可以写如下代码了:下面是一个完整版,可以直接使用microchip的库函数,本程序只是仿真调试过,未在多个芯片通信过,仍在制作中。
#include "stdio.h"
#include "can18xx8.h"
#include "pic18fxx8.h"
unsigned long NewMessage;
BYTE NewMessageData[8];
BYTE MessageData[8];
BYTE NewMessageLen;
enum CAN_RX_MSG_FLAGS NewMessageFlags=1;
BYTE RxFilterMatch;
void main()
{
//int a;
//int b;
CANInitialize(1, 5, 7, 6, 2, CAN_CONFIG_VALID_XTD_MSG);
while(1)
{
// Application specific logic here
// Check for CAN message
if ( CANIsRxReady() )
{
CANReceiveMessage(&NewMessage,NewMessageData,&NewMessageLen,&NewMessageFlags);
if ( NewMessageFlags & CAN_RX_OVERFLOW )
{
// Rx overflow occurred; handle it
}
if ( NewMessageFlags & CAN_RX_INVALID_MSG )
{
// Invalid message received; handle it
}
if ( NewMessageFlags & CAN_RX_XTD_FRAME )
{
// Extended Identifier received; handle it
}
else
{
// Standard Identifier received.
}
if ( NewMessageFlags & CAN_RX_RTR_FRAME )
{
// RTR frame received
}
else
{
// Regular frame received.
}
// Extract receiver filter match, if it is to be used
RxFilterMatch = NewMessageFlags & CAN_RX_FILTER_BITS;
}
// Process received message
// Transmit a message due to previously received message or
// due to application logic itself.
if ( CANIsTxReady() )
{
MessageData[0] = 0x01;
CANSendMessage( 0x02,MessageData,1,CAN_TX_PRIORITY_0
&CAN_TX_STD_FRAME &
CAN_TX_NO_RTR_FRAME);
}
// Other application specific logic
} // Do this forever
// End of program
}
以上均是参考文档并进行了修正,由于中间总是报错,为了大家让CAN更容易,谢谢大家!
