From 865c4859d710870245ae7954e729edcaf442a921 Mon Sep 17 00:00:00 2001 From: Luke Hoersten Date: Sun, 14 Jun 2026 20:11:21 -0500 Subject: Default name = MAC; brief wake on boot; drop dead touch defences MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Seed viewport_name with the full base MAC, colons stripped (e8:f6:0a:e0:90:94 → "e8f60ae09094"). Stable across reboots, globally unique, 12 alphanumeric chars — well inside the mDNS hostname limit even with the "viewport-" prefix. - Add a mac_str field to viewport_state and expose it as the new "mac" key in GET /state and as a "mac" line on the info screen. - "Configured" no longer requires a viewport_name (it always has the MAC default); the scrypted URL alone gates outbound POSTs and the loading-vs-info screen choice. - Strip viewport_name[0] fallbacks in http_api / mdns / local_screens now that the field is never empty. - Replace the wake-on-boot-stays-on behaviour with a ~600 ms flash followed by sleep — long enough for the FT5426 touch IC to come out of its initial unresponsive state, short enough that an idle device doesn't burn the backlight. - Drop the touch defensive cruft added when we were chasing a PoE-power theory: the DEV_MODE=0x00 write at init, the touch_reset_pulse() call at init, and the runtime wedge-self-heal in the polling loop didn't actually fix anything — the wake-on-boot flash did. Also delete the display_touch_reset_pulse() helper since it now has zero callers. --- main/viewport_state.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'main/viewport_state.h') diff --git a/main/viewport_state.h b/main/viewport_state.h index 4e6fbd6..264d07d 100644 --- a/main/viewport_state.h +++ b/main/viewport_state.h @@ -20,7 +20,8 @@ typedef enum { // Read-mostly snapshot of device state used by /state.
