EmulationIDF.h File Reference

ESP-IDF-native emulation of exactly the Arduino surface TinyGPU/Drivers and TinyGPU/Input actually call - delay()/millis(), pinMode()/digitalWrite()/digitalRead() (+ HIGH/LOW/OUTPUT/INPUT/ INPUT_PULLUP), SPIClass/SPISettings (+ MSBFIRST/LSBFIRST/SPI_MODEn) and a global SPI (driver/spi_master.h), and TwoWire (+ a global Wire) on the legacy driver/i2c.h controller driver.

Detailed Description

ESP-IDF-native emulation of exactly the Arduino surface TinyGPU/Drivers and TinyGPU/Input actually call - delay()/millis(), pinMode()/digitalWrite()/digitalRead() (+ HIGH/LOW/OUTPUT/INPUT/ INPUT_PULLUP), SPIClass/SPISettings (+ MSBFIRST/LSBFIRST/SPI_MODEn) and a global SPI (driver/spi_master.h), and TwoWire (+ a global Wire) on the legacy driver/i2c.h controller driver.

This is the ESP-IDF branch of TinyGPU/Emulation.h's fallback - include that instead of this file directly; it decides whether a real Arduino core is available, and routes here only when it isn't and ESP_PLATFORM is defined (a plain ESP-IDF component build via idf_component_register, without arduino-esp32).

Not a general Arduino-core replacement - only covers the calls this library's own Drivers/Input headers make (verified by grepping them), not the full Arduino API. A sketch built against this fallback that calls other Arduino functions will still need its own additions here, or the real Arduino core after all.

Not compiled or hardware-tested as part of this repo's own CI (which only exercises the desktop/Arduino-Emulator and Arduino-IDE paths) - treat it as a reasonable-effort starting point and verify against your exact IDF version/target before relying on it on real hardware.
