How To Use GPIO on the Raspberry Pi with C++

20190116· PIN NUMBERING IN WIRING PI. Pin number in wiringPi is not straightforward because the author used a wiring numbering scheme that does not refer to either the GPIO number or pin number. Long story short, when the Pi was first released, there were 8 useable GPIO pins which were numbered 0 to 8, but later releases have now seen many more GPIO with ...


Benchmarking Raspberry Pi GPIO Speed | Code and Life

20120703· The Raspberry Pi Wiki gives a nice C code example for true hardwarelevel access to the GPIO. The interfacing is slightly more difficult, but code isn’t too bad. I took the example program and simplified the main method after setup_io() to this: // Set GPIO pin 4 to output INP_GPIO(4); // must use INP_GPIO before we can use OUT_GPIO OUT_GPIO(4); while(1) { GPIO_SET = 1<<4; GPIO_CLR = …

Understanding SPI Communication using Raspberry Pi ...

20170327· Raspberry Pi 3 supports two chip select (CE) lines to interface with two SPI slave devices. If you try to locate the SPI pins in the pin diagram above, you can see that GPIO10 and GPIO11 represent CE0 and CE1. A little closer inspection will also reveal the MISO, MOSI, and SCLK pins. Look out for them. SPI In Action. Let’s build a real working circuit to demonstrate SPI in action. We will ...

Unlike some other solutions for using the Raspberry Pi''s GPIO pins, wiringPi provides access to more advanced features, such as enabling the internal pullup or pulldown resistors. Usage. To use this library, you must either run as root, or set the WIRINGPI_GPIOMEM environment variable. (Set it to anything; the value does not matter.) However, PWM will not work if WIRINGPI_GPIOMEM is set ...


Raspberry Pi Wiring/Quick Disconnect for GPIO : MAME

Raspberry Pi 2. 22 gauge wire. Quick disconnect connectors from Amazon. Now I''m looking for a way to connect the wiring. From what I can search through this subreddit, people seem to be using 22 gauge copper wiring with quick disconnect crimped connectors. This all seems straight forward to me and it is something I seem I should be able to do.
