DESIGN SCHEMATICS PARALLEL PORT TO GPIO
[PDF]
VSC7511/12 Hardware Design Checklist
ence design schematics as a basis and retain the reference design’s use of GPIO (parallel as well as serial) when-ever possible to minimize software changes. Keep a log of the major changes (for example, port numbering, PHY addresses, GPIO, and SGPIO) and provide this log when there is design review or when starting software custom-ization.
[Resolved] Defining parallel port using GPIO pins - Other
I want to create a parallel port, 8-bits wide in the TIVA Launchpad. Port B is already available for use but some of the pins are conflicting with another use for them. Suppose, i wanted to define a port say. PORT J which has PB7, PB6, PA1, PA2, PA3, PD2, PD3, PD4 as the 8 pins in parallel, how would I have to define the port?People also askIs a parallel port a gpio?Is a parallel port a gpio?If you can still find one, it's worth mentioning that a true parallel port is about as close to a GPIO as you'll find in an off-the-shelf PC. Classic implementations lack some flexibility in that many of the pins have fixed direction, and some are inverted, but people have been working around that for years.Reference: electronicskexchange/questions/44943/using-gpio-in-pcSee all results for this questionWhat does GPIO stand for in microcontroller?What does GPIO stand for in microcontroller?GPIO stands for “General Purpose Input/Output pins“. In fact, most of the pins in a typical microcontroller are GPIO pins except for some special pins. The special (non-GPIO) pins are usually the following ones:Input/Output Ports Tutorial - GPIO PinsSee all results for this questionWhat are GPIO pins?What are GPIO pins?What are GPIO pins?

That is not GPIO, but it can be used as a command/status channel to talk to a helper micro which has GPIOs.Using GPIO in PC - Electrical Engineering Stack ExchangeSee all results for this questionFeedback

This document and all the accompanying design documentation (for example schematic and PCB files) are covered by the H-Storm Non-Commercial License (HSNCL). The FPGA is hooked up to the printer port on one side and to the JTAG and GPIO pins on the other. the FPGA have to pull the JTAG_MODE signal (pin 55) low to direct the parallel port

Microcontroller GPIO ports referred to as Parallel Ports
Microcontrollers typically have several groups of GPIO pins, labeled PORTA, PORTB, PORTC etc. or something similar (perhaps P0, P1, etc.). Each of these ports is referred to as a parallel I/O port in the manufacturers' datasheets, because all pins of the port can be acted upon in parallel by one machine instruction width of the port dictated by the data path width of
GitHub - garlick/pi-parport: retro parallel port for
pi-parport This 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.

AN 494: GPIO Pin Expansion Using I2C Bus Interface in
To reduce package size and pin count, the number of general purpose I/Os are limited in many microprocessor-based systems. However, if the system has an I 2 C interface, this design example shows how to add additional GPIO pins via the I 2 C bus. The supported Altera devices are an excellent choice to implement industry standard interfaces, such as the I 2 C.[PDF]

Three registers determine the configuration of each pin in PORT x: GPIO_Px_MODEL (pins 0 to 7) or GPIO_Px_MODEH (pins 8 to 15), GPIO_Px_DOUT, and GPIO_Px_CTRL. The following code configures pin 5 from Port C as a digital input with pull-up and filter. The MODE5 bitfield from GPIO_PC_MODEL
