Hi everyone! 
Delighted to be here.
I would like to introduce FreeHIL — an open-source Hardware-in-the-Loop (HIL) infrastructure designed to be easily portable across any microcontroller or target evaluation board.
Why it might interest this community:
1. Validation of your open-source hardware:
When building open-source hardware boards, automated verification testing can often be a headache without expensive commercial test benches.
FreeHIL provides a structured software abstraction layer to trigger and monitor GPIO, ADC, DAC, PWM, UART, and CAN lines directly from Robot Framework.
2. Build open HIL hardware boards:
You can simply port FreeHIL onto your own microcontroller-based hardware (or a standard evaluation board) and build a HIL (Hardware-in-the-Loop) simulator. This allows you to create a low-cost off-the-shelf HIL simulator, or you might be interested in getting an OSHWA certification for your hardware design.
I would love to hear your thoughts and ideas on this approach. Your feedback, experiences, and potential contributions would be deeply appreciated!
Feel free to check out the project here:
