Hi.

Pharo works on Beaglebone. And I am pretty sure that it will work on other ARM/Linux based computers

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,

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. On Tue, Jul 25, 2017 at 10:06 PM, Attila Magyar <m.magyar3@gmail.com> wrote:

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. **Roughly equivalent to 1998 $2300 Mac_G3/333 ( https://www.frc.ri.cmu.edu/~hpm/book97/ch3/processor.list.txt). 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. cheers -ben

Hi, There are other interesting tiny boards that should fit well with Pharo-IOT (we should of course: https://www.raspberrypi.org/products/raspberry-pi-zero/ <https://www.raspberrypi.org/products/raspberry-pi-zero/> but then, there are many and it should be relatively easy to get running there: beaglebone pocket: https://beagleboard.org/pocket <https://beagleboard.org/pocket> Nanpi Duo: http://www.friendlyarm.com/index.php?route=product/product&path=69&product_i... <http://www.friendlyarm.com/index.php?route=product/product&path=69&product_i...> CHIP https://getchip.com/pages/chippro or industrial platforms like http://www.variscite.com/variscite-products <http://www.variscite.com/variscite-products>

Hi,

thanks for the links :)

Yes i am still working on this topic, however i chose to focus on Raaspbery Pi. It is quite handy to have an embedded linux to experiment things. I do not have a public page on my projects at the moment, but there is the Pharo-iot github project that gather work of the community on the subject (https://github.com/pharo-iot). <https://github.com/pharo-iot)> Did you manage to launch Pharo on the Teensy boards?

Hi Steven,

I found your message and was wondering if you're still working on this. I did some IoT stuff with the little Teensy 3.2 boards, which I find very convenient to use. The new 3.6 board has more memory (1Mb flash and 256Kb RAM).

See info and seller here: - https://www.pjrc.com/teensy/techspecs.html <https://www.pjrc.com/teensy/techspecs.html> - https://www.antratek.com/boards/arduino-compatible/teensy <https://www.antratek.com/boards/arduino-compatible/teensy>

Can I follow your progress anywhere?

Kind regards, Jonathan

Hi Jonathan we are interested too. Stef On Wed, Mar 28, 2018 at 2:53 PM, Jonathan van Alteren <jvalteren@essentialimagination.nl> wrote:

No, I haven't done much with Pharo yet, least of all adapt it to run on an IoT device ;-) I'm interested though, but it will take me considerable time to reach that level of experience.

I've got a BeagleBone Black running some Node.js things though, and would love to add Pharo to the mix. I like the BB better than the Raspberry Pi because it has 4Gb MMC on board, instead of having to rely on an SD card (which can get corrupt in case of power loss).

I will try Pharo IoT in time, either on RPi or BB. Thanks!

Jonathan
