DESIGN SCHEMATICS PARALLEL PORT TO GPIO
Microcontroller GPIO ports referred to as Parallel Ports
The term parallel port originated from the port where printers were connected to. In the context of microcontrollers, it may make sense to refer to a group of pins as a parallel port if they are read or written in parallel, but not in general. For instance, certain GPIO pins of an 8-bit port may indeed represent a serial port.
Is there a GPIO IC that has a parallel interface
The W65C21 PIA (Parallel Interface Adapter), also made by Western Design Center (WDC) along with the W65C02S, is a parallel GPIO chip specifically designed to work with the address/data/clock interface of the 65xx series of chips.
Home Automation/ Control a Relay With Your Parallel Port
Using the parallel port for relay control software is the most reliable way as you have pin to pin connection from your parallel port to your relay board. This eliminates the need of using drivers to control the serial or USB port.
GitHub - garlick/pi-parport: retro parallel port for
Aug 04, 2019This is a Raspberry Pi HAT that implements a PC-style parallel port. GPIO pins are organized as data, status, and control registers. The HAT includes a buffer chip that converts from the GPIB 3V3 logic to signals that conform to IEEE 1284. A 26 pin IDC header on the board connects to your DB25 connector.
PCIe Controller Chips support serial, parallel, and GPIO.
Aug 04, 2010Consisting of 4 devices, MCS99XX Series enables variety of PCI ExpressÂ® to multiple I/O connectivity options. Serial ports are compatible with RS232, RS422, and RS485 standards and support throughput from 50 bps to 16 Mbps, while parallel port is compatible with IEEE 1284 and supports Nibble, Byte, SPP, ECP, and EPP modes.
c - Possible to use a 9 Pin Serial port as "GPIO" using
Yes, sure you can do this. There are a number of lines on the serial port that can be used as GPIO. One of them (on pin9 I think) is RING which is used on old serial modes to signal incoming calls. You can read it like this: unsigned mask = TIOCM_RNG; unsigned status; int fd; // your serial port file descriptor.
Schematics | Parallel bus to I2C-bus controller
The PCA9564 is a parallel-bus to I2C-bus protocol converter and interface by NXP Semiconductors. The PCA9564 Evaluation Board demonstrates the Philips PCA9564 I2C bus controller’s ability to interface between a master (connected to its parallel bus and its control signals) and any master and slave devices connected to its I2C -bus.
GPIO to LPT: Is it possible? : raspberry_pi
Parallel port is 5 volt logic, while GPIO is 3.3 volts. This LLC would step the GPIO signal up to the needed 5 volts, allow up to 200 mA of current to be supplied (vs. 20 mA for raw GPIO), and would act as a buffer between the printer and the Pi. This should work.
Direct CNC Control With The Raspberry Pi | Hackaday
May 15, 2018For the record, I wanted to get an A8 and improve it instead of simply buying a good printer from the get-go because it seemed like a good way to practice my CAD and mechanical design
