Meadow.Cloud
- Improved OS support for OtA updates
- Improved subscription downgrade experience
v1.9.0
This is a huge update for Meadow! Highlights include:
- Overall Stability - With the last few releases we've knocked out nearly ever OS and networking priority-zero issue. In many cases, Meadow.OS should now be stable for weeks or months without issue.
- OS Multitasking Stability - We've implemented the
Round-Robin
thread scheduler which brings a massive upgrade to how the OS manages and switches between threads and brings a new level of stability aroundThread
andTask
operations. - SPI DMA - We’ve added SPI DMA which reduces CPU load when communicating with SPI devices and can lead to a 30% increase in drawing performance with SPI displays!
- Unified Meadow.Desktop - Meadow.Desktop got a massive simplification by unifying the launcher between Windows/macOS/Linux, meaning you now only need a single application that will run in any dekstop context for full graphics simulation.
- Meadow.CLI v2 - THe Meadow.CLI got a huge upgrade in its codebase with a complete re-write focused on stability, consistency, and ease-of-use.
Note - starting with v1.9.0.0 and CLI v2.0, you’ll need to create a free Wilderness Labs account to download new versions of the Meadow OS.
Meadow.OS
- Round-Robin - .NET threads are now using the round-robin OS scheduler. This brings a much more advanced task scheduling paradigm to embedded and that better matches traditional .NET execution behavior and resolve issues of apps “livelocking” because of a tight loop preventing progress under the First-In, First-Out (FIFO) scheduler.
- SPI DMA - SPI DMA has been enabled for all SPI data transfers. Use of it should be transparent, providing approximately 3x throughput speed for SPI peripheral devices.
- Coprocessor Threading Stability - Changes to the threading on the coprocessor were made, resulting in greater stability for network requests
- Deep OS Internal Stability Fixes - Several low-level fixes & improvements that provide more stability throughout the entire OS stack.
Meadow.Core
- Support has been added for F7 multi-platform targeting. One app assembly can now contain IApp instances for multiple F7 hardware targets. (add link to docs).
IPixelDisplayProvider
interface added for Meadow.Desktop platforms.- SensorService now auto-registers any
ISleepAwarePeripherals
it knows about. - Improvements to Core interrupt handling in F7 platforms.
- Interrupts events changed from containing a DateTime to a system tick (for performance reasons).
- OtA Downloads now report progress via an event.
- Added “reason” to network disconnection events on F7 platforms.
- Added preliminary support for Raspberry Pi 5.
Meadow.Foundation
- FT232H/FTDI Driver refactored to support multiple devices at one time and to use the same driver (FT2xxx) for all modes.
- Improved partial update logic in MicroGraphics and TftSpi display drivers.
- BME688 gas resistance fix. Thanks to community member
Laszlo
for the fix. - SCD40 events fix.

Meadow.Cloud
- Bug fix for Azure Event Grid data serialization
- For over-the-air updates, we exposed a new event,

Meadow.Desktop
- We have added support for
Meadow.Desktop
as a target. This allows a single app to target Windows, Mac or desktop Linux with auto-platform detection and simulatedIPixelDisplay
. New templates are coming soon to makeMeadow.Desktop
app creation simple.
IoT Accelerators
- Our GNSS Tracker got a big update with its v2 hardware iteration (which is packed with more sensors than its predecessor), including a revamped demo application displaying accurate atmospheric sensor data along with battery and solar input voltage.
Meadow.Tooling
- CLI v2.0 has shipped! This is a massive rework of the command line tool used to communicate with Meadow devices and manage firmware. Note, with this new release, you will need to create a free Wilderness Labs account and sign in before downloading firmware updates.
