- Updated version to 2.3.4 in library.json and library.properties - Enhanced .gitignore to exclude additional files - Refactored ESPUI.cpp and ESPUI.h for platform-specific handling - Introduced pico-gui and rp2040Example for Raspberry Pi Pico W - Updated platformio.ini for Pico W and RP2040 examples

…uards to all examples Core library fixes: - Set ESPUI_USING_FREERTOS=0 for RP2040/RP2350 (no FreeRTOS on arduino-pico) - Guard xSemaphoreTake/Give behind ESPUI_USING_FREERTOS macro - Remove corrupted preprocessor fragment in ESPUIclient.cpp - Unify ESPUIclient to use AsyncWebSocketClient* on all platforms - Remove duplicate RP2040 sync begin() code path All examples (Arduino IDE + PlatformIO) updated with: - Platform detection: ESP32 / ESP8266 / RP2040 WiFi includes - DNSServer/captive portal guarded (#if !defined(ARDUINO_ARCH_RP2040)) - Hostname handling per platform (setHostname/hostname/skip) - ChipID per platform (getEfuseMac/getChipId/rp2040.getChipID) - MDNS guarded for RP2040 (not available on arduino-pico) - WiFi.begin uses .c_str() on RP2040 (same as ESP32) Deleted separate pico examples (merged into existing): - examples/pico-gui, examples/pico-all-controls, examples/rp2040Example - pio_examples/pico-gui, pio_examples/rp2040Example Updated library metadata: - library.json: RP2040/RP2350 keywords, raspberrypi platform - library.properties: RP2040 in architectures and dependencies Tested: All 6 Arduino IDE examples compile for rp2040:rp2040:rpipicow
Add RP2040 Pico W build environment to all 6 PlatformIO example platformio.ini files using maxgerhardt/platform-raspberrypi with earlephilhower arduino-pico core and ayushsharma82/RPAsyncTCP. All 6 PIO examples compile successfully for rpipicow: - gui: 528KB Flash, 74KB RAM - tabbedGui: 477KB Flash, 73KB RAM - completeExample: 485KB Flash, 73KB RAM - completeLambda: 485KB Flash, 73KB RAM - gui-generic-api: 477KB Flash, 73KB RAM - prepareFilesystem: 202KB Flash, 72KB RAM Also add .pio/ to .gitignore to exclude PIO build artifacts.

Hey there Claude =P This looks interensting, I will get back to reviewing but I am generally low on time for this project, hope to get to it in 1-2 weeks |
|
Hi there! Actually I used AI to help the PR description and the code changes were AI-assisted. |
|
Hm, somehow this fails to build for me... https://github.com/earlephilhower/arduino-pico.git does not have a platform.json even, feels like there might be a mistake here... I guess the plan was rather using something like https://github.com/maxgerhardt/platform-raspberrypi.git ? did you run the pico gui successfully ? |
|
Yeah I did run the pico gui successfully using arduino ide. Update: This should resolve your build failure. |
Fix/rp2040 build and pico test
Set ESPUI_USING_ASYNC to 0 for RP2040 and RP2350 and conditionally compile async-only APIs. Wrapped beginSPIFFS, beginLITTLEFS and the memory-mode begin() implementations behind #if ESPUI_USING_ASYNC in src/ESPUI.cpp, added appropriate #endif adjustments, and gated the onWsEvent declaration in src/ESPUI.h. Also added WebServer.h and WebSocketsServer.h includes for the non-async path so RP2040/RP2350 build with the synchronous server/websocket implementation. These changes ensure the project builds correctly on RP2040/RP2350 platforms that don't use the async stack and avoid exposing async APIs where not supported.
