Hi,
I try to use the serial port to communicate with an Arduino. On Linux, no problemo. I can open the serial port with the following code:
| serialPort baudRate comPortNumber |
baudRate := 31250.
comPort := '/dev/ttyACM0'.
serialPort := SerialPort new
baudRate: 31250;
dataBits: 8;
stopBitsType: 1;
parityType: 0;
yourself.
"the port is closed to ensure that it will be free"
serialPort close.
(serialPort openPort: comPort) isNil
ifTrue: [ ^self error: 'COM port not available' ]
ifFalse: [ serialPort inspect ].
serialPort close.
But on MacOS X (10.11.6), the same code used with /dev/cu.usbmodel1411 doesn't run. The error is "Cannot open '/dev/cu.usbmodel1411'". I'm sure that is the correct serial port. If I type "more -f /dev/cu.usbmodel1411" in a terminal, the rx/tx leds of the Arduino are blink.
Someone has an idea about this problem that is not specific of the Arduino but concerns the generic usage of the serial port with Pharo?
Best regards
Olivier
ps: I can't test on Windows but I'm interested by a feedback.
