To prevent data corruption when using multiple SPI devices on the same bus, care must be taken to ensure that they are only accessed from within the main loop, or from the interrupt routine, never ...

The Zephyr SPI functions are slightly harder to use then than their Arduino counterparts, but they are also more sophisticated. The SPI driver is easy to acquire at compile time: static const struct ...

I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...

The tactile device is thin, flexible, and has 25 stimulation generating points within a 2 cm × 2 cm area. To achieve wearable, to install the driving circuit close to the device, we use high voltage ...
