Back to #RISCV PineCone #BL602 @PINE64 ... With Bosch BME280 Temperature / Humidity / Air Pressure Sensor

#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"

Reading Sensor Data on Apache #NuttX RTOS ... Here are the steps

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

#ZigLang reads the #NuttX Sensor Data and converts to Fixed-Point Numbers

#ZigLang reads the BME280 Humidity Sensor on Apache #NuttX RTOS

Here's how we import #NuttX Functions into #ZigLang

#ZigLang Slice is a Pointer and a Length

Here's why #ZigLang Slices are a little safer than C Strings

#ZigLang Sensor App reads BME280 Sensor on Apache #NuttX RTOS 🎉

Our #ZigLang Sensor App works for other #NuttX Sensors too

Up next for #ZigLang on #NuttX ... Visual Programming with Blockly!

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

https://lupyuen.github.io/articles/sensor?16#lorawan-and-visual-programming

Here's why our #ZigLang Sensor App uses Fixed-Point Numbers (instead of Floating-Point)

@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.
