This library controls the INA239, a device that measures voltage, current, power, and temperature. The library is not tested with hardware yet, feedback welcome. The library is written to be able to ...

When compiling for an ESP32-S3 (and apparently also an -S2) with the Arduino framework, the SPI component always selects SPI 2 (FSPI) in the generated C++ code, even if interface: spi3 is specified.

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 ...

Interfacing with the outside world is a fairly common microcontroller task. Outside of certain use cases microcontrollers are arguably primarily useful because of how easily they can interface with ...
