​The beauty of this design? It scales to an Mx8 kbd matrix. Just keep an array of state variables for rows 0..M-1. Select a row, read 8 columns into raw_sample, and pass pointers to the row's state into a modded tick.
​Efficient✅️ Simple✅️ Deterministic✅️

I'm building a 12-bit universal sequencer engine for my #HomeAutomation framework. It's a micro-interpreter that treats a binary blob as a program, params and data, to drive a beeper, haptics, fans, room LED lighting and RGB status LEDs, each with custom post-processing. #Embedded

Sneak peek at the HA project’s button controller.

Extracted the parallel bit-interleaved debouncer so everyone can reuse it. Features: Symmetric (press/release), Periodic polling (high EMI immunity), Zero counters (bitwise-only), Scalable N×S matrix in a single register ⬇️

In an age of AI-cloud-dependent, wireless "IoT slop," we need a robust, open-source, decentralized, wired system. Fast, documented, and MQTT/Ethernet-free, it uses STM32 low-power nodes for total reliability and easy maintenance/setup.
I’m working on one. 🛠️⚡ #HomeAutomation #OpenSource
