这是PC机间相互通信的例子，程序“require”为用查询方式实现，程序“interrupt”为 用中断方式实现

(1) 用单脉冲发生器的输出作为中断请求信号使8259A产生中断,进入中断后显示一个字符串。(2) 中断请求通过8259的IRQ2端输入，中断源可以是片外8253定时器输出的脉冲，并把8253的OUTO和总线槽IR02连接好。 (3) 编写程序,要求每次主机响应外部中断IRQ2时,显示字符串“THIS IS A 8259A INTERRUPT!”(或其它串)，中断十次后，程 ...

The IA-32 Software Developer’s Manual, Volume 3: System Programming Guide (Order Number 245472), is part of a three-volume set that describes the architecture and programming environment of all IA-32 Intel&reg Architecture processors. The IA-32 Software Developer’s Manual, Volume 3, describes the ...

This will sample all 8 A/D-channels by the continous mode. Each end of conversion will call an interrupt routine, where the AD-channel is put to Port4[2..0] and the upper nibble of the result is put to Port4[7..4]. Port 4 is connected to the user LEDs of the FlashCan100P Evaluation-Board

This example provides a description of how to set a communication with the bxCAN in loopback mode: - transmit and receive a standard data frame by polling at 100Kbit/S - transmit and receive an extended data frame with interrupt at 500Kbit/S - lit some LEDs depending of the program succeed or not ...

This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The r ...
