Guide is in the making, please stand by 🙂

All shipped AtsroCan Boards/Bridges have the current Firmware already uploaded!

Preperation:

Download the archive from the article attachements

Inside you’ll find the needed sketches, firmwares and libraries:

Firmwares:

Sketches & Libraries:

SHADOW_MD_Sketch is the standard Mega2560 sketch. Please upload it to the Mega with Arduino IDE.
The needed libraries are in the library archive.

Arduino IDE: https://www.arduino.cc/en/software (please use version 1.8.19)

Software:

ESP_flash_download_tool_3.9.6 ist the upload tool for the ESP32. For latest version look here:
https://www.espressif.com/en/support/download/other-tools

Uploading the firmware to the ESP32:

Upload any example sketch via Arduino IDE:

First of all, it’s recommended to upload any example sketch to the ESP32 via Arduino IDE. Please select “the “ESP32 Dev Module”.

Manual for including ESP32 into the Arduino IDE: https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/

Upload the Firmware:

To upload the firmware you need the Flash Download Tool.

Connect the ESP32 via an USB Cable to the computer and run the tool.

Select ESP32 and Develop

Select the Firmware you want to flash and set the start adress to 0x10000

Click start on the bottom left and watch the terminal output. Once it’s sucessfully finished the “IDLE” changes to “Finish”.

When the upload won’t start, try this:

• press and hold the reset button
• press and hold the program/en button
• release the reset button, the ESP will boot in program mode
• release the program button
• upload the sketch

If it still doesn’t work you might have forgotton to upload a testsketch via Arduino IDE before.
Same behaviour could happen there, just try the button method.

Configuring the Firmware

AstroCan Pro Dual Shield Board (& AstroCan Pro Dual Board):

To view the configuration commands, please open the serial monitor in the Arduino IDE and enter “/help”.
