Project description
📌 Overview kzeta23 publishes AR22 LCU v1.1 as a Korean-documented STM32F446 firmware repository for a dual-range gamma radiation detector. The public GitHub profile does not publish a name, country, or organization, so this post keeps those fields conservative and focuses on the firmware evidence. AR22 LCU v1.1 adds a WIZnet W5500 Ethernet TCP logging path to a validated radiation detector firmware. The detector counts pulses from two Geiger-Mueller tube channels, calculates dose rate with adaptive filtering, drives a 256x64 SSD1322 OLED and alarm output, and then streams the current dose…
