From 89f61eab2d0cbb535d6567b6cffbe5451ec36966 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 2 Feb 2026 12:25:27 +0000 Subject: [PATCH 1/6] feat: Add ESP32 climb preview display firmware for Waveshare LCD Add firmware for the Waveshare ESP32-S3 Touch LCD 4.3" to display climb previews from Boardsesh party sessions. Features: - LovyanGFX-based display driver for 800x480 RGB parallel LCD - Real-time climb preview via GraphQL subscription - Shows climb name, angle, difficulty, and hold visualization - WiFiManager for easy WiFi configuration - Web-based configuration portal for API key and session ID - Touch screen support (GT911 controller) - Double-buffered rendering with PSRAM sprites The display uses the same controllerEvents subscription as the LED controller, showing colored circles for lit-up holds matching the web UI colors. https://claude.ai/code/session_01KQdMgLnHiXmpn2TxKcS6Pd --- embedded/libs/climb-display/library.json | 23 ++ .../libs/climb-display/src/climb_display.cpp | 306 ++++++++++++++ .../libs/climb-display/src/climb_display.h | 208 ++++++++++ .../projects/climb-preview-display/README.md | 192 +++++++++ .../climb-preview-display/partitions.csv | 6 + .../climb-preview-display/platformio.ini | 57 +++ .../src/config/display_config.h | 142 +++++++ .../src/config/hold_positions.h | 137 ++++++ .../climb-preview-display/src/main.cpp | 391 ++++++++++++++++++ 9 files changed, 1462 insertions(+) create mode 100644 embedded/libs/climb-display/library.json create mode 100644 embedded/libs/climb-display/src/climb_display.cpp create mode 100644 embedded/libs/climb-display/src/climb_display.h create mode 100644 embedded/projects/climb-preview-display/README.md create mode 100644 embedded/projects/climb-preview-display/partitions.csv create mode 100644 embedded/projects/climb-preview-display/platformio.ini create mode 100644 embedded/projects/climb-preview-display/src/config/display_config.h create mode 100644 embedded/projects/climb-preview-display/src/config/hold_positions.h create mode 100644 embedded/projects/climb-preview-display/src/main.cpp diff --git a/embedded/libs/climb-display/library.json b/embedded/libs/climb-display/library.json new file mode 100644 index 00000000..45c8756e --- /dev/null +++ b/embedded/libs/climb-display/library.json @@ -0,0 +1,23 @@ +{ + "name": "climb-display", + "version": "1.0.0", + "description": "Climb preview display driver and renderer for Waveshare ESP32-S3 LCD", + "keywords": ["esp32", "lcd", "display", "climbing", "boardsesh"], + "repository": { + "type": "git", + "url": "https://github.com/marcodejongh/boardsesh.git" + }, + "authors": [ + { + "name": "Boardsesh", + "email": "hello@boardsesh.com" + } + ], + "license": "MIT", + "frameworks": "arduino", + "platforms": "espressif32", + "dependencies": { + "lovyan03/LovyanGFX": "^1.1.12", + "bblanchon/ArduinoJson": "^7.0.0" + } +} diff --git a/embedded/libs/climb-display/src/climb_display.cpp b/embedded/libs/climb-display/src/climb_display.cpp new file mode 100644 index 00000000..50aab5fb --- /dev/null +++ b/embedded/libs/climb-display/src/climb_display.cpp @@ -0,0 +1,306 @@ +#include "climb_display.h" + +// Global instance +ClimbDisplay Display;

When ledUpdateCallback is set, LED updates are forwarded to the callback instead of directly controlling LEDs. This enables the climb-preview-display to work alongside the board-controller in proxy mode. https://claude.ai/code/session_01KQdMgLnHiXmpn2TxKcS6Pd --- .../src/graphql_ws_client.cpp | 79 ++++++++++++++++--- .../graphql-ws-client/src/graphql_ws_client.h | 16 +++- .../projects/climb-preview-display/README.md | 39 +++++++++ .../climb-preview-display/src/main.cpp | 73 ++++++----------- 4 files changed, 148 insertions(+), 59 deletions(-) diff --git a/embedded/libs/graphql-ws-client/src/graphql_ws_client.cpp b/embedded/libs/graphql-ws-client/src/graphql_ws_client.cpp index df94e5a5..c4cd1f36 100644 --- a/embedded/libs/graphql-ws-client/src/graphql_ws_client.cpp +++ b/embedded/libs/graphql-ws-client/src/graphql_ws_client.cpp @@ -1,6 +1,26 @@ #include "graphql_ws_client.h" + +// Conditionally include LED and BLE dependencies +#if __has_include() #include +#define HAS_AURORA_PROTOCOL 1 +#else +#define HAS_AURORA_PROTOCOL 0 +#endif + +#if __has_include() #include +#define HAS_NORDIC_BLE 1 +#else +#define HAS_NORDIC_BLE 0 +#endif + +#if __has_include() +#include +#define HAS_LED_CONTROLLER 1 +#else +#define HAS_LED_CONTROLLER 0 +#endif GraphQLWSClient GraphQL;

Changes: - Create lilygo-display shared library with ST7789 driver and UI rendering - Add climb-queue-display project with WiFi AP mode for first-time setup - Add ws:// and wss:// protocol prefix support to graphql-ws-client - Add AP mode support to wifi-utils library for captive portal setup Features: - Shows current climb name, grade (with color), and angle - Generates QR codes linking to climb in Kilter/Tension app - Displays climb history (last 3 climbs) - Status bar showing WiFi, backend, and BLE connection status - Web config portal for WiFi, API key, and session setup Note: BLE proxy mode is disabled pending NimBLE 1.4.x API compatibility fixes.
