[問題] 關於微電腦介面控制的問題
Write the software that programs counter 2 to generate an 80KHz
square wave if the CLK input to counter 2 is 8 MHZ
Program the 16550 for operation using six data bits,even parity
,one stop bit,and a Baud rate of 19,200 using a 18.432 MHz clock.
(Assume that the I/O ports are numbered 20H and 22H)
Develop an ISA bus interface that is decoded at addresses 310H-
313H.This tnterface must contain an 8255 accessed via these port
addresses.(Don't forget to buffer all inputs to the ISA bus card)
Creat an ISA bus interface that allows four channels of anolog output
signals from 0 to 5.0V each.These four channels must be decoded at I/O
addresses 300H,310H,320H,and 330H.Also develop software that
supports the four channels.
PCI bus,USB bus 微介面的I/O電路(ex.LCD A/D,D/A,8254,8255,6550)電路原理(程式)
不知道有沒有大大看得懂...拜託了...
這裡是隱版嗎!?
一位版有拜託我PO的
有他的MSN hishawtaco@yahoo.com.tw
他很急...謝謝拉
P.S 真的不是我自己
