In the default JetPack 6.2 distribution, GPIO pins are not marked as bidirectional. In order to change that, here is an example device tree overlay file. This is for Pin 7, which is GPIO9/AUD_MCLK.

In kernel 4.14 there is no support for using a GPIO pin as a PPS generator, only a GPIO PPS client is available. This driver is derived from the current parallel port PPS generator and provides a PPS ...

In our previous tutorial Getting Started with the RASPBERRY PI ZERO, we had an overview Raspberry Pi zero W and setup the Pi Zero. In this tutorial we are going to design a simple LED circuit and ...

For microcontrollers, an LED blinking program is equivalent to the “hello world” program. In our previous tutorial, we learned how to get started with STM8S103F3 Development Board and how to set up ...

For both the Raspberry Pi and BeagleBone Black, there’s a lot of GPIO access that happens the way normal Unix systems do – by moving files around. Yes, for most applications you really don’t need ...

There was a time when USB to serial hardware meant one company: FTDI. But today there are quite a few to choose from and one of the most common ones is the WCH CH341. There’s been support for these ...

General purpose input-output (GPIO) pins are the simplest peripherals. The link to an object under control (OUC) may become inadvertently unreliable due to many reasons: a loss of contact, short ...
