Solved Design An I O Interfacing Circuit That Uses The 8255 Chegg Design an i o interfacing circuit that uses the 8255 ppi to decode the 16 bit address lines of the 803865 x at base address fffoh using memory mapped i o. the pin diagram of the 8255 is shown below. the pin diagram of the 8255 is shown below. Question 2 (30 marks) design an i o interfacing circuit that use the 8255 ppi to decode the 16 bit address lines of the 80386sx at base address foo0h. the interfacing circuit should use the isolated i o technique.
Solved Parallel I O Port 8255 Interfacing Q1 The 8255 Shown Cheggођ Circuit diagram to connect the 8085 with 8255. you can understand the connections in the following steps. first of all, we need supply power to both 8085 and 8255 by connecting vcc and gnd pins to the appropriate sources. reset out pin of 8085 is connected to the reset pin of 8255. when the microprocessor is reset, it also resets the 8255 via. Programmable peripheral interface 8255. Important features of the 8255 are listed below: 8255 is a programmable peripheral interface, available in the form of a 40 pin ic which works on a power supply of 5 v dc. it is compatible with a wide range of microprocessors and microcontrollers, making it widely popular. it has three 8 bit i o: ports a, b, and c. Example 1: interface an 8255 chip with 8086 to work as an i o port. initialize port a as output port, port b as i p port and port c as o p port. port a address should be 0740h. writean alp to sense switch positions sw0–sw7 connected at port b. the sensed pattern is to be displayed on port a, to which 8 led's are connected, while port c.
