I2C Write on #BL602 #NuttX works ONLY when we do an I2C Read AFTER the I2C Write ... So quirky! 🤔

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

#BL602 #NuttX now writes correctly to I2C Registers! 🎉 There's an extra I2C Read at the end, but it should be harmless

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

What happens if #BL602 #NuttX writes to an I2C Register without reading it afterwards? The I2C Write gets truncated or zeroed 🤔

Now that #RustLang Embedded HAL runs OK on Apache #NuttX RTOS ... Let's test the Rust Driver for BME280 Sensor!

https://github.com/lupyuen/rust-i2c-nuttx#rust-embedded-driver-for-bme280

We add the #RustLang Driver for BME280 Sensor to our #NuttX App ... By editing Cargo.toml

https://github.com/lupyuen/rust-i2c-nuttx#rust-embedded-driver-for-bme280

Here's how we read the BME280 Sensor in our #RustLang App for #NuttX RTOS

@lupyuen What is that used for?

@kreyren That's the Bosch BME280 Sensor for Temperature, Humidity and Air Pressure: https://www.bosch-sensortec.com/products/environmental-sensors/humidity-sensors-bme280/

@lupyuen Hmm.. can it arduino?

@kreyren Yep there's a BME280 Driver for Arduino: https://create.arduino.cc/projecthub/dragos-iosub/arduino-bme280-sensor-how-to-115560
