Implement a USB PD protocol analyzer, a USB PD trigger board or a more sophisticated power sink using a few additional components and simple Arduino code. Supports several STM32 microcontrollers.

This is the Arduino driver code for the HackEEG Arduino Due shield for the TI ADS1299 EEG system-on-a-chip. The TI ADS1299 is a 24-bit 8-channel ADC meant specifically for EEG, with 24x programmable ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

Introduced in 1984, the Psion Organiser series defined the first generation of electronic organizers or PDAs (personal digital assistants). Even though these devices are now over 30 years old, the ...

The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn’t ...

PD Micro is the first Arduino-compatible board with USB Type-C Power Delivery, which allows your project to make use of voltages from 5-20 V. It’s perfect for projects that would require separate ...

In Part I of this article, I briefly mentioned the generic USB driver in the context of getting a USB device to communicate through it easily, with no custom kernel programming. Unfortunately, I ...

In my last column [see LJ December 2002], we covered the serial layer in the 2.5 (hopefully soon to be 2.6) kernel tree. We mentioned in passing that a USB-to-serial driver layer in the kernel helps ...
