From 2a471e288c16b91a7186a60b3fb84dd55a494c7a Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Thu, 8 Oct 2020 09:47:40 -0400 Subject: New port: AIGO EROS Q / EROS K The Q and K have a slightly different case, but the hardware under the shell is completely identical. These models are rebadged versions: * Hifiwalker H2 (== Q) * AGPTek H3 (== K) * Surfans F20 (== K) Other notes: * Significant improvements in the shared Hiby-platform launcher/loader * SD card can theoretically be hot-swapped now * Support external USB mass storage! * Some consolidation of Hiby-platform targets * Some consolidation of plugin keymaps Todo/known issues: * Keymaps need to be gone over properly * Convert to HAVE_SCROLLWHEEL?
