I/O pins, Ports and Circuits - blogspot.com
Most I/O setup is done in the cpu_map.h file. Note: All I/O is 3.3V and the current capability is very low. Do not connect any I/O directly to relays, solenoids, etc. There are more features than available I/O pins, so you need to determine what features you want. Here are the pins you can use. Be
Zynq-7000 SoC Packaging and Pinout
All of the I/O pins used on the board are defined as to which pin they appear on (what they get connected to by signal name) and which I/O standard they …

The Coral Dev Board provides access to several peripheral interfaces through the 40-pin expansion header, including GPIO, I2C, UART, and SPI. All I/O pins on the 40-pin header are powered by the 3.3V power rail, with a programmable impedance of 40 - 255 ohms, and a max current of ~82 mA.
Digital I/O Techniques - Measurement Computing
Before you start writing programs to run on a BASIC Stamp to add special effects to your electronics projects, you must first build the circuit(s) that will connect to the I/O pins on the Stamp. Once the circuit is constructed, you can then write a program that controls the circuits that you’ve connected to each […]

Digital I/O Techniques - Measurement Computing i/o pins
When a device is powered on or reset, digital I/O pins are usually, by design, set to high impedance input. There may be enough drive current available from the inputs to turn on any connected output devices, such as solid state relays (SSRs).
Digital I/O - Beginners Guide to PIC Programming
pinMode (pin_number, mode) Because the Arduino digital I/O pins can be used for either input or output, you should first configure the pins you intend to use for digital I/O with this function. pin is the. number of the pin you wish to configure. mode must be one of three values: INPUT, OUTPUT, our INPUT_PULLUP.

Digital Pins. In addition to the specific functions listed below, the digital pins on an Arduino board can be used for general purpose input and output via the pinMode(), digitalRead(), and digitalWrite() commands. Each pin has an internal pull-up resistor which can be turned on and off using digitalWrite() (w/ a value of HIGH or LOW, respectively) when the pin is configured as an input.

I/O Pins: Voltages, Currents, and Standards - Community Forums
Upon startup or reset, all I/O pins default to input (high impedance), meaning each cogs DIRA register is initialized to zero. Each cogs OUTA register is initialized to zero as well, but this low (ground) state is not reflected on the pin until the pin is set to the output direction (via DIRA).
How to Use the Arduino’s Digital I/O - Projects
USB-based digital I/O devices from Measurement Computing are designed with built-in pull resistors. TTL to Solid State Relays Many applications require digital outputs to switch high AC and DC voltages on and off, and to monitor the presence or absence of high AC and DC voltages.
I/O Pins
an I/O pin is a ‚0™, then the pin is configured for an output. An easy way to remember this is that a ‚1™ looks like an I (Input) and a ‚0™ looks like an O (Output). All port pins are defined as inputs after a Reset. 12.2.2 PORT Registers
