#ZigLang reads BME280 Sensor ... With Apache #NuttX RTOS on #RISCV #BL602 ... All shall be explained in this article

https://lupyuen.github.io/articles/sensor?1

Apache #NuttX RTOS shows BME280 Sensor as 2 devices ... "baro0" and "humi0"

#ZigLang has a "defer" feature ... Super handy for cleaning up! 👍

#ZigLang Visual Programming with #NuttX Sensors ... Maybe Blockly can do this 🤔

@lupyuen Many of these do internally behave like separate sensors, so this can make sense. The last one I implemented for @RIOT_OS (LSM303AGR, in #RustLang) also shows as an accelerometer and a separate magnetometer.

@lupyuen That's a slick feature! It should cut down on the number of instructions used as well as the amount of high level code used.
