Installing Firmware From Source

If you are building your own Marauder or assembling the ESP32 Marauder Kit, it will be necessary to run your own initial install of the ESP32 Marauder firmware. The following method uses the Arduino IDE.

1. Follow the IDE setup instructions under Arduino IDE Setup
2. Download and install the following libraries using the ZIP library installer under Sketch>Library>Add .ZIP Library
   • lv_arduino
   • LinkedList
   • TFT_eSPI
   • JPEGDecoder library
   • NimBLE
   • NeoPixel
   • ArduinoJson
   • SwitchLib

3. Follow these instructions for installing ESP32 Spiffs Tool

4. Install the CH340 Drivers

5. Download or clone this repository

6. Open esp32_marauder.ino in your Arduino IDE

   • If you're using the analog battery measuring circuit, go to the MenuFunctions.h and change "#define BATTERY_ANALOG_ON" to 1

7. Define your hardware version with the following lines in config.h. To determine which version you posses, see Marauder Versions

8. Plug your ESP32 into a USB port and select the COM port under Tools>Port

9. Select the appropriate ESP32 module under Tools>Boards

   • If you are using the original ESP32 Marauder: LOLIN D32
   • If you are using the ESP32 Marauder V6: LOLIN D32
   • If you are using the ESP32 Marauder Kit: Adafruit ESP32 Feather

10. For partition scheme, select Minimal SPIFFS (Large APPS with OTA)

11. Click ESP32 Sketch Data Upload and wait for the SPIFFS upload to finish

12. Copy my User_Setup.h into your TFT_eSPI library folder to replace the one already in there

13. Click the upload button
