New hardware interface replaces the discontinued MCP2221A model — but loses ADC/DAC support and comes with an SPI caveat.

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 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 ...

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 ...
