Porting the #NuttX Sensor Test from C to #ZigLang 😬
https://github.com/lupyuen/visual-zig-nuttx#sensor-test-app-in-c
#ZigLang #BL602 passes Floats to printf() and hits Weirdness ... Here's the workaround
https://github.com/lupyuen/visual-zig-nuttx#fix-floating-point-values
#ZigLang prints #NuttX Sensor Data as Fixed-Point Numbers
https://github.com/lupyuen/visual-zig-nuttx#floating-point-link-error
Oops here's the correct algo ... Tested OK with #ZigLang "comptime" and "@compileLog" 👍
#ZigLang reads a #NuttX Barometer and Humidity Sensor (Bosch BME280)
https://github.com/lupyuen/visual-zig-nuttx#read-barometer-sensor
Back to #RISCV PineCone #BL602 @PINE64 ... With Bosch BME280 Temperature / Humidity / Air Pressure Sensor

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
https://lupyuen.github.io/articles/sensor?7#import-nuttx-functions
#ZigLang Slice is a Pointer and a Length
Here's why #ZigLang Slices are a little safer than C Strings

Compiling our #ZigLang Sensor App for 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)
https://lupyuen.github.io/articles/sensor?17#appendix-fixed-point-sensor-data
@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.
Apache #NuttX RTOS shows BME280 Sensor as 2 devices ... "baro0" and "humi0"
