This software for  Raspberry Pi OS \"Buster\" (64-bit) adds support for ESP32 processors to the Arduino IDE.\n\nStart and exit the Arduino IDE. This creates the directory `~/.arduino15`  in your home directory, and the file `~/.arduino15/preferences.txt`.\n\nWith the Arduino IDE **not** running, edit `.arduino15/preferences.txt`, and add the following line:\n```\nallow_insecure_packages=true\n```\nThis allows the use of unsigned packages like this one. Also tick \"Verbose output during upload\".\n\nStart  the Arduino IDE. In *File --\u003e Preferences --\u003e Additional Board Manager URLs:* paste the following url:\n```\nhttps://raw.githubusercontent.com/koendv/xtensa-esp32-elf-raspberrypi/master/package_esp32_dev_index.json\n```\nPress OK.\n\nOpen *Tools -\u003e Board: -\u003e Boards Manager*\nIn the search field, type \"ESP32\". Install the \"esp32\" board package. Ignore any messages \"Warning: forced trusting untrusted contributions\".\n\nIn the Tools menu select the ESP32 cores as compilation target. As an example, if using an ESP32 Wrover choose *Tools-\u003eBoard: -\u003e ESP32 Arduino-\u003eESP32 Wrover Module* .\n\n\n## Notes\n\nThis esp32/esp32s2 gcc cross-compiler is for 64-bit raspberry only.\n\nBuild script: [build.sh](build.sh).
