The only two historical references I see on forum.world.st are from 2006 & 2010. http://forum.world.st/parallel-port-access-on-Linux-td46506.html http://forum.world.st/Physical-Etoys-released-td1574259.html and they have some link rot.
I'd guess your best approach would be to get something working in pure C, and then provide functions that Pharo can call via FFI. Alternatively, from personal experience when I used to hoard such old parts, it may be economic use of your time to throw the old board away, and use a modern microcontroller. What you learn could facilitate more opportunities, and this stuff just keeps getting cheaper, while parallel ports get more expensive while knowledge of them keeps getting less relevant. Maybe a $20 ESP32 with 18 ADC channels + MQTT https://www.sparkfun.com/products/13907 http://wiki.jackslab.org/ESP32_Onchip_Sensor http://www.instructables.com/id/Power-and-Temperature-Data-Logger-With-ESP32-and-A/ https://github.com/tuanpmt/esp32-mqtt http://forum.world.st/MQTT-for-Squeak-td4919880.html#a4920629 http://forum.world.st/MQTT-for-Pharo-td4927759.html#a4928045 https://developer.ibm.com/recipes/tutorials/connect-an-esp32-to-the-watson-iot-platform/ Or use a Raspberry Pi... https://core-electronics.com.au/tutorials/temperature-sensing-with-raspberry_pi.html that can run Pharo directly, but I'm not sure what access to pins is currently available. Again you could go the FFI route, or someone else might advise. cheers -ben On Sat, Jun 10, 2017 at 8:57 AM, Facundo Vozzi <[email protected]> wrote: > Hi, > I need to access to the Parallel Port in order to use an old > Analog/Digital board to sense temperature in a micro brewery.
