Avnet/Azure_Sphere_SK_ADC_RTApp
Azure Sphere Advanced Application supporting a realtime application and and OLED display.
A tutorial sample for the Avnet Azure Sphere MT3620 Starter Kit that pairs a high-level (A7) app with a real-time (M4) app, exchanging ADC readings over the inter-core messaging API and showing them on the kit's OLED. It's aimed at people working through Avnet's step-by-step hardware blog post, not at anyone looking for a general Azure Sphere reference.
The inter-core messaging path is a genuinely useful reference if you've never wired up A7-to-M4 communication on MT3620 — it shows the full message framing (component ID, reserved bytes, payload) rather than hand-waving it. The OLED and sensor glue code (i2c.c, oled.c, sd1306.c, lsm6dso/lps22hh register files) is real working driver code pulled from Avnet's reference design, not stubs. Two separate CMake projects for the A7 and M4 apps keep the bare-metal RTApp cleanly separated from the high-level app, matching how Azure Sphere actually partitions cores.
Azure Sphere itself is a deprecated platform — Microsoft end-of-life'd it, so anyone cloning this in 2026 is building for hardware with no real future, and the repo hasn't been touched since Feb 2020. There are no automated tests at all, which is forgivable for a hardware demo but means every claim in the README is unverifiable without owning the exact Starter Kit board. Setup requires Visual Studio, a specific SDK version, a USB-to-serial breakout board, and admin-mode driver installs — there's no path for anyone without that exact hardware and OS to even try it. With 5 stars and 6 forks and no CI, there's no signal this is maintained or that the beta inter-core APIs it depends on still work against current Azure Sphere SDKs.
