8255 ic manual

Example 1: Interface an chip with 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 H. 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 CFile Size: KB. circuit and versatility Intel Corporation has introduce chip, which is commonly called Programmable Peripheral Interface [PPI]. The has 24 I/O pins divided into 3 groups of 8 pins each. The groups are denoted by port A, port B and port C respectively. Every one of the ports can be configured as either an input port or an output www.doorway.ru Size: 1MB.  · The IC is a Programmable Peripheral Interface (PPI) which is used to interface the microprocessors with the various devices. The PPI chip is a 40 pin IC. In the IC, there are 24 input/ output lines. In this IC, the input/ output lines are divided into e different ports: Port A, Port B, and Port C. Each port contain 8 data lines.

A - Programmable Peripheral Interface. The A is a general purpose programmable I/O device designed to transfer the data from I/O to interrupt I/O under certain conditions as required. It can be used with almost any microprocessor. It consists of three 8-bit bidirectional I/O ports (24I/O lines) which can be configured as per the. Szétszedtem, már ez az ic volt forrasztva- nem is túl szépen. Átforrasztottam, de nem javult meg. végig követtem az analóg jelet és a digit hangerő szabályzó ic-ig eljut, de belőle már nem jön ki. A tápfeszek rendben +-7,3 (6,8V) 5,18V (5,05V) viszont a vezérlő jelek nincsenek meg. The Intel (or i) Programmable Peripheral Interface (PPI) chip was developed and manufactured by Intel in the first half of the s for the Intel microprocessor. The provides 24 parallel input/output lines with a variety of programmable operating modes. The is a member of the MCS Family of chips, designed by Intel for use with their 80microprocessors and.
