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.
(1) 用單脈沖發生器的輸出作為中斷請求信號使8259A產生中斷,進入中斷后顯示一個字符串。(2) 中斷請求通過8259的IRQ2端輸入，中斷源可以是片外8253定時器輸出的脈沖，并把8253的OUTO和總線槽IR02連接好。
(3) 編寫程序,要求每次主機響應外部中斷IRQ2時,顯示字符串“THIS IS A 8259A INTERRUPT!”(或其它串)，中斷十次后，程序退出。
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® Architecture processors.
The IA-32 Software Developer’s Manual, Volume 3, describes
the operating-system support environment of an IA-32 processor, including memory management,
protection, task management, interrupt and exception handling, and system management
mode. It also provides IA-32 processor compatibility information. This volume is aimed at operating-
system and BIOS designers and programmers.
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 frequency defined by <SMB_FREQUENCY> constant
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 received data are stored in the DST_Buffer.
The DMA channel transfer complete interrupt is enabled to generate an interrupt at
the end of the buffer transfer. As soon as the transfer is completed an interrupt is
generated and in the DMA channel interrupt routine the transfer complete interrupt
pending bit is cleared.
The data counter is stored before and after the transfer to show that all data has been
transfered.
TransferStatus gives the data transfer status where it is PASSED if transmitted and
received data are the same otherwise it is FAILED
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.
