From 6a924963e51422410a082eda7fea5db76c4cd398 Mon Sep 17 00:00:00 2001 From: Matt Edholm Date: Fri, 8 May 2026 23:48:20 -0400 Subject: [PATCH] fix(build): move data_dir to [platformio] section so uploadfs sees the panel files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PlatformIO silently ignores data_dir inside [env:…] blocks (it warned "Ignore unknown configuration option `data_dir`" on every run, but we read past it). Without a recognized data_dir, uploadfs packed the entire project data/ root into LittleFS, putting every file under /waveshare73-v1/ instead of /. The firmware looks at /, so draw_from_lfs fell back to its solid-yellow epd_fill — a blank yellow panel after a fresh uploadfs. Moving the directive to the project-level [platformio] section makes PlatformIO honor it. All envs currently target the V1 panel so a single project-level data_dir is fine; when a second panel ships, swap via an extra_scripts shim that picks the dir from \$PIOENV before uploadfs runs. --- platformio.ini | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/platformio.ini b/platformio.ini index 56f7f98..5f33e27 100644 --- a/platformio.ini +++ b/platformio.ini @@ -10,6 +10,15 @@ ; Old envs preserved as historical snapshots — re-flashing units in the ; field stays a one-line `pio run -e --target upload` command. +; data_dir lives at project level (PlatformIO ignores it inside [env:…] +; blocks — the silent ignore once led to a LittleFS upload that put every +; file under /waveshare73-v1/ instead of /, blanking the panel to the +; epd_fill yellow fallback).
