From d5cdb6b4e4424d80ac9bfd8e12c129334c23d6f2 Mon Sep 17 00:00:00 2001 From: Luke Hoersten Date: Sun, 14 Jun 2026 15:53:33 -0500 Subject: M3 WIP: DSI bring-up + state machine + identity overlay MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DSI / panel: - LDO_VO3 acquired at 2500 mV (VDD_MIPI_DPHY) — without this the PHY PLL busy-waits forever inside esp_lcd_new_dsi_bus. - PSRAM bumped to 200 MHz (CONFIG_IDF_EXPERIMENTAL_FEATURES) to keep the DPI fed without underruns. - Pi-7"-style 800x480 panel init (REG_POWERON, PORTA/PORTB/PWM/PORTC) + 16-bit RGB565 framebuffer with portrait-mode rotation buffer in PSRAM. Currently shows garbled output — known issue, next commit switches to the TC358762-bridge-aware init sequence. State + UX: - viewport_state simplified to AWAKE/ASLEEP only; "unconfigured" is a flag, not a state. Tap always toggles; content choice (identity vs frame) is driven by the configured flag. - BOOT button arms a 15 s identity overlay via local_screens_overlay; expired callback returns to prior state. - Boot-done indicator: two backlight flashes (no usable LED GPIO on the Waveshare board — GPIO 35 BOOT is shared with EMAC TXD1). - Best-effort subsystem init in app_main; display init deferred to its own task so a panel hang can't block networking. Display test pattern: solid R/G/B for 2 s each on boot to characterize the garble independent of text rendering. --- main/button.c | 27 ++------------------------- 1 file changed, 2 insertions(+), 25 deletions(-) (limited to 'main/button.c') diff --git a/main/button.c b/main/button.c index 9ac34a1..26e7cff 100644 --- a/main/button.c +++ b/main/button.c @@ -25,28 +25,11 @@ static const char *TAG = "button"; #define LONG_HOLD_MS 5000 #define OVERLAY_MS 15000 -static esp_timer_handle_t s_overlay_timer; - -static void overlay_expired(void *arg) -{ - if (display_is_up()) { - local_screens_restore_for_state(); - // Caller (state_machine_set) had backlight off if asleep — the - // overlay turned it on.
