The firmware was built with the Arduino IDE. Here's how to set it up:

  1. Install the Arduino IDE from https://www.arduino.cc/en/software.
  2. Download this repository as a .zip file (available here: https://github.com/jblanked/FlipperHTTP/archive/refs/heads/main.zip).
  3. Unzip the file and within that src/flipper-http folder, double-click the flipper-http.ino file to open it in Arduino IDE.
  4. Go to Preferences/Settings, and add the following to the Additional Boards Manager URLs field:
https://github.com/earlephilhower/arduino-pico/releases/download/5.5.1/package_rp2040_index.json,https://github.com/Ameba-AIoT/ameba-arduino-d/raw/dev/Arduino_package/package_realtek_amebad_early_index.json,https://dl.espressif.com/dl/package_esp32_index.json
  1. In Boards Manager:
  • Search for rp2040 and install the Raspberry Pi Pico/RP2040/RP2350 package by Earl Philhower.
  • Search for esp32 and install the ESP32 package by Espressif Systems.
  • Search for realtek and install the Realtek Ameba Boards (32-bit ARM Cortex) package by Ameba-AIoT (this is not available on Linux).
  1. In Library Manager:
  • Search for TFT_eSPI and install the TFT_eSPI library by Bodmer.
  • Search for ArduinoJson and install the ArduinoJson library by Benoit Blanchon.
  • Search for ArduinoHttpClient and install the ArduinoHttpClient library by Arduino.
  • Search for FlashStorage and install the FlashStorage_RTL8720 library by Khoi Hoang.

  1. Restart your Arduino IDE.

  2. Hold the BOOT button while connecting your USB data cable to your board.

  3. In Tools, click Board and then select your specific board type (e.g., Raspberry Pi Pico W). Note, the BW16 is Ai-Thinker BW16 (RTL8720DN) and WiFi Developer Board is ESP32S2 Dev Module

  4. Select the serial port to which your board is connected to.

  5. If you plan on developing/compiling for the PicoCalc, then in the User_Setup.h file in the TFT_eSPI library folder (usually located at ../../Documents/Arduino/libraries/TFT_eSPI/User_Setup.h or ../Arduino/libraries/TFT_eSPI/User_Setup.h) and:

Replace it with the following code snippet:

#define USER_SETUP_ID 60
#define ILI9488_DRIVER
#define TFT_RGB_ORDER TFT_BGR
#define TFT_MISO 12
#define TFT_MOSI 11
#define TFT_SCLK 10
#define TFT_CS 13
#define TFT_DC 14
#define TFT_RST 15
#define TFT_SPI_PORT 1
#define SPI_FREQUENCY 25000000
#define SPI_TOUCH_FREQUENCY 2500000
#define LOAD_GLCD
#define LOAD_FONT2
#define SMOOTH_FONT
#define TFT_INVERSION_ON
  1. Back in the Arduino IDE, in Tools menu:
  • if you're compiling for a Raspberry Pi Pico device: change the Flash Size to 2MB (Sketch: 1984KB, FS: 64KB) (or 4MB (Sketch: 4032KB, FS: 64KB) if compiling for a Raspberry Pi Pico 2W device) and CPU Speed to 200MHz.
  • if you're compiling for an ESP32 device: change the Partition Scheme to Minimal SPIFFS (... with OTA/190KB SPIFFS) and Upload Speed to 115200.
  • if you're compiling for the BW16, change Auto Flash Mode to Enable and Upload Speed to 921600.
  1. In the board.hpp file, set your board type by uncommenting your board definition. For example, for a BW16, the line should look like this:
#define BOARD_BW16 10        // AI-Thinker BW16 (RTL8720DN)

instead of

// #define BOARD_BW16 10        // AI-Thinker BW16 (RTL8720DN)
  1. Finally, click Sketch in the menu, then select Upload.
