What can you do with a programmable RGB LED light strip, #STM32WLE5, #LoRa radio, an accelerometer and a pressure sensor? Well, I'm cooking up something interesting :) So far I have the LED "hello world" going. #STM32

Next step is to add physics to this connected LED concept prototype. This 4-LED wide "critter" smoothly accelerates in random directions. Too bad video upload won't work... #LoRa #STM32 #IoT

Alright, let's try linking to YouTube. Connected LED light strip demo phase 2 youtu.be/-ngiGPVpt5o

Our stm32-secure-patching-bootloader github.com/firmwaremodule… is an "unbrickable" over-the-air or over-the-wire #firmwareupdate solution for any #stm32 #IoT product.

If you could re-design the #MCU #IoT operating system what it look like? We think it would be entirely callback-based, and concepts like threads, tasks and processes become obsolete. We're working on this right now and will be sharing updates as we move along this exciting path!

Our new upcoming #IoT #operatingsystem is called Measurement{Earth} 2.0: Powering the World of IoT. It has an API inspired by #nodejs yet remains 100% C-based without any heap or hidden behind-the-scenes memory allocation.

Like nodejs it is fully event-driven and callback-based, and leverages the concept of streams in a big way. The stream layer optimally manages all I/O flow in and out of the device with DMA for UART, I2C and SPI.

In addition to the familiar nodejs Stream and Buffer modules, we are adding select Crypto, Net (LwIP/Ethernet), LoRaWAN and a callback-driven AT command processor for developing drivers to talk to GNSS, Cellular and Satcom devices.

We're also adding pre-built sensor drivers for a variety of sensors. When the operating system is not doing anything it places the device in its lowest possible power state, automatically.

With this operating system it is possible to develop powerful IoT remote sensing applications in a short time that would otherwise take a traditional development team months and years to achieve.

We also already have a capable #firmware update and management system and #bootloader in our portfolio. The addition of the Measurement{Earth} 2.0 Operating System to our firmware portfolio will be a game changer!

Getting ready for stm32-secure-patching-bootloader release v.1.4.0! Some of the dev boards we test on. Quite an eclectic mix of hardware and capabilities ranging from STM32L0 through to STM32H7. #stm32 #bootloader

Just got device time sync going over #lorawan application layer. Matching gateway's packet Rx time to the lorawan stack's TxDone interrupt results in a surprisingly accurate time transfer.

Our new Earth Lower Power Protocol for bridging #blockchain Sensor Modules to Antelope and #TELOS over @Helium is now in live testing!

Finally moved my two active #airquality monitoring units onto the Telos mainnet after over a year on and off the testnet. See them here: measurement.earth
