All programs were tested using a breadboard containing a DS80C320, 32K Program memory, 32K Data memory, two 8-segment bar graph LEDs/drivers, and an 11.0592 MHz crystal. The four 8-segment bar graph LEDs/drivers were connected to ports 1, and 3 to display their pins states.

High-speed Interface to Host EPP Parallel Port * Version: 1.0 * Last updated: 2001.12.20 * Target: All AVR Devices with 12 I/O pins

(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 example demonstrates how the C8051F06x SMBus interface can communicate // with a 256 byte I2C Serial EEPROM (Microchip 24LC02B). // - Interrupt-driven SMBus implementation // - Only master states defined (no slave or arbitration) // - Timer4 used by SMBus for SCL low timeout detection // - SCL ...

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 ...

This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the IAR-STM32-SK evaluation board. It shows basic use of I/O, timer and the interrupt controllers. Displays running lights on the board LED s.

A huge program that consist of polling mechanism of a main controller to 32 slave in a fireman intercom environment. Including the handset condition detection, LCD controller, keypad controller, interrupt handling and ADC.
