Our #NuttX App writes to an I2C Register ... By calling #RustLang Embedded HAL

https://github.com/lupyuen/rust-i2c-nuttx#write-i2c-register

Here's how we call #RustLang Embedded HAL to read an I2C Register ... Our #NuttX I2C App is much simpler now!

https://github.com/lupyuen/rust-i2c-nuttx#read-i2c-register

We wrap the #NuttX I2C ioctl() interface ... And expose as #RustLang Embedded HAL

https://github.com/lupyuen/rust-i2c-nuttx#read-i2c-register

#RustLang Embedded HAL defines a standard API for I2C Operations ... Let's wrap the #NuttX I2C ioctl() Commands and expose as Rust Embedded HAL interfaces

https://github.com/lupyuen/rust-i2c-nuttx#rust-embedded-hal

Our #NuttX #RustLang I2C App reads a BME280 Register correctly! 🎉

Here are the #NuttX I2C Types ... Ported from C to #RustLang

https://github.com/lupyuen/rust-i2c-nuttx#read-i2c-register-in-rust

Here's how we call #NuttX's I2C Interface from #RustLang ... The "unsafe" way

https://github.com/lupyuen/rust-i2c-nuttx#read-i2c-register-in-rust

Apache #NuttX exposes an ioctl() interface for the I2C Port ... Let's call it from #RustLang

https://github.com/lupyuen/rust-i2c-nuttx#from-c-to-rust

Will #RustLang talk I2C on Apache #NuttX RTOS and #BL602? Let's find out!

Pascal on Apache #NuttX RTOS 👍

What's Next for #NuttX and #BL602 ... Porting the Rust I2C HAL to NuttX!

What's inside the #NuttX Sensor Test App

https://lupyuen.github.io/articles/bme280?20#sensor-test-app

Here's how we read the BME280 Sensor with #NuttX Sensor Test App

https://lupyuen.github.io/articles/bme280?19#run-bme280-driver

How we minimised the changes when porting the Zephyr BME280 Driver to #NuttX OS

https://lupyuen.github.io/articles/bme280?18#zephyr-driver-modified-for-nuttx

What's inside our bundled BME280 Driver for #NuttX OS

https://lupyuen.github.io/articles/bme280?17#inside-the-bundle

Here's how we bundle the Zephyr BME280 Driver inside our #NuttX Driver

https://lupyuen.github.io/articles/bme280?16#bundle-nuttx-and-zephyr-drivers

Our #NuttX BME280 Driver registers the Barometer and Humidity Sensors at startup

https://lupyuen.github.io/articles/bme280?15#register-sensors

Our #NuttX BME280 Driver defines the operations for the Barometer and Humidity Sensors

https://lupyuen.github.io/articles/bme280?12#sensor-operations

Our #NuttX BME280 Driver combines 2 sensors ... Here's why
