Build

This firmware is using STM32CubeIDE, compatible with STM32CubeMX - project supports code regeneration without altering the ST25TB part.

Hydrabus is using a STM32F405, you need its stack from ST: https://www.st.com/en/embedded-software/stm32cubef4.html - but the IDE care about it itself.

For reference, it was developped with STM32Cube MCU Package for STM32F4 series version 1.28.0 (maybe patch1 ?), if you want to use another version, you may have to edit the .ioc file then regenerate the project.

Flash

You can flash the firmware from the IDE itself, but you can also use STM32CubeProgrammer, the GUI or the CLI.

By example for DFU mode in CLI: STM32_Programmer_CLI --connect port=usb1 --download st25tb_kameleon_stm32_hydrabus_hydranfc_v1.hex --verify

Notes

--erase all can be added before --download
port=usb1 is not mandatory, you can also add a sn=___
- use STM32_Programmer_CLI --list to be sure before...

Question & Answers

1. Can I buy one?

Yes, maybe, Benjamin VERNOUX ( @bvernoux ) mades them, if you're lucky on https://hydrabus.com/shop/ or maybe you can still find them:

Hydrabus : https://www.digikey.fr/en/products/detail/benjamin-vernoux/HYDRABUS-V1/15652912
HydraNFC : https://lab401.com/fr/products/hydranfc

... but Benjamin is now more focus on HydraNFC v2 - https://hydrabus.com/hydranfc-shield-v2-specifications/ - with a better NFC chip : ST25R3916(B)
