That was only Pharo on a laptop interfacing to the ESP32 over USB serial port.�� Suitable to provide a GUI interface to a microcontroller application, but not actually Pharo running on the ESP32.

The esp32 is not capable of running Pharo unfortunatelly. It's not Linux
based, it has a realtime operating system called FreeRTOS and the amount of
memory it has is also quite limited. It's more like a microcontroller than a
single board computer.

The ESP32 is exactly a microcontroller, but I'm hopeful it might have the capacity to run Pharo. ��
Onboard it has 520KB SRAM and offboard can use 8MB SPI-SRAM (at 80MHz) and 16MB SPI-Flash memory,
which seems close to feasible to run a minimal image on.�� Without a GUI loop I'd be its 266MHz 600MIPS** processor��might be sufficient for Pharo to run small embedded applications. ��

And each year these cheap $20 microcontrollers get more powerful. FreeRTOS may be a likely candidate to support each new platform (http://www.freertos.org/RTOS_ports.html) may make an interesting target for a VM port, even if only the StackInterpreter. ��

btw, from wikipedia... "FreeRTOS can be thought of as a 'thread library' rather than an 'operating system', although command line interface and POSIX-like I/O abstraction add-ons are available.�� The kernel itself consists of only three C files." ��One obstacle to overcome would be how the VM makes use of memory mapped files, since that facility seems unavailable on FreeRTOS. ��

Hi,

i am looking for:

- small hardware, boards/computers, "embeddable" devices, etc. that can run Pharo (except Raspberry pi that i already know)

- robots, flying drones or things alike with an open linux which can possibly run Pharo

Could somebody points me to documentation or web sites where such things can be found ?

Thanks,

Steven.
