[Pharo-project] Make arduino work on linux with cog vm

by Mariano Vicente

Hi Everybody. I'm just started with Pharo, and Arduino. And i like to comunicate both. I instaled the package sent by Ricardo Moran in a Pharo 1.4 with the Cogvm from the Jenkins server, but i can't make the serials port works. The Arduino board, i have, is connected to usb, wich ubuntu detects as /dev/ttyACM0. I tried opening serial ports, like this: sp:=SerialPort new. sp openPort: '/dev/ttyACM0'. sp openPort: 'ttyACM0'. sp openPort: 'ACM0'. sp openPort: '/ttyACM0'. But all they fail with a error saying ""Cannot open..." After that, i have also, tried this: (1 to: 10000) select:[:port | [SerialPort new openPort:port;close. true] on:Error do: [false]] and had a empty collection. And also tried giving full permissions to the port and executed the vm sudoed... Are serial ports working on ubuntu?. Do i have to download a special vm?. (I would like to do a demo of arduino on monday, at work, and i would like to do in Pharo.) Cheers, Mariano

probably the ConfigurationOfSeaside30 should be updated to use Zn.

Re: [Pharo-project] Compiler bug!!!

Igor, great catch. I prefer the attached. Strictly, the index needs to be fixed correctly before the node's size is determined, since it could change (not in this bytecode set, but in some future one it could).

BTW, ZnServer is already in the image, you don't need anything else but the ZnZincServerAdaptor from Zinc-Seaside. There is a magic Monticello config for that as well, but I can't help you with that.

Re: [Pharo-project] Refactor method

by StÃ©phane Ducasse

Dario you should really try to migrate. 1.0 is so old. About the message, the refactoring engine is checking and sometimes the messages are weird but again lukas spent a huge effort improving it.
