Installing the Firmware on an ESP32¶
Installing TiltBridge on an ESP32 can be accomplished using either Fermentrack or the Espressif esptool.py script.
Installation Using Fermentrack¶
Installation via Fermentrack is incredibly easy as it leverages the existing “firmware flash” workflow. To flash via this method simply log into your Fermentrack installation, choose “Flash Device” from the devices menu, select the “ESP32” device family, and follow the prompts. When prompted to choose a firmware to flash simply choose “TiltBridge”.
Installation using esptool.py¶
TiltBridge can also be installed using esptool.py. Although slightly more involved, this method does not require the use of a Raspberry Pi running Fermentrack.
The command below will automatically detect & flash any Espressif chips connected to the computer running esptool.py. Please leave only the device you are setting up connected to the computer to avoid the risk of misflashing.
- Install esptool.py using the instructions here.
- Download all three of the TiltBridge firmware files from GitHub - spiffs.bin, firmware.bin, and partitions.bin
- Connect the ESP32 board to the computer you will be using to flash
- Open a command prompt and run the flash command
esptool.py --chip esp32 --before default_reset --after hard_reset write_flash 0x10000 firmware.bin 0x8000 partitions.bin 0x3D1000 spiffs.bin
