I can never get any serial output on the serial window.

 

void setup(){

Serial.begin(9600);

}

void loop(){

Serial.print('A');

// or Serial.write('TEST');

delay(500);

}

 

i'm building from source. currently from d5632bb6a844dd59c57029ec7a56d890db80201b

(also, my window says "Energia ${version}" so there's may be something wrong with the way i'm building... i.e. just typing `ant`)

 

i'm using a rev1.4 board with a G2553, nothing else attached.

 

also tried using minicom to listen on port /dev/ttyS0 to S3 and ttyACM0 with 8N1 9600, same silence.

tried all the ways... with it in parallel (as the board comes) with it crossed, with the pins opens :)

 

still nothing...

 

I do get different kernel messages depending on how i plug it:

dmesg with pins in parallel

Oct 14 12:00:50 hobo kernel: [ 5324.976078] usb 3-1: USB disconnect, device number 9

 

with the pins crossed sometimes the serial port mentioned by the kernel does not show up on the energia list. and minicom gives me "cannot open /dev/ttyACM0: Input/output error"

 

Also, i'm assuming this would all work via the USB interface right? on both those pages there's no info about extra pins to be used.

hum... it didn't showed up on the wiki before ... ah, i was looking at home, not "Pages"

 

let me try this. thanks.

 

update:

took some time to build the module... the zip file had a all files with DOS termination and i was getting errors in the build logs such as: "directory /perfectly/valid/dir do not exist" only to find out the ^M at the end of the path didn't show up in the logs as well :?

 

after converting to unix (

vim file -c "set ff=unix" -c "wq"

) install.sh, Makefile, *.c, *.conf it worked.

 

My new dmesg:

[26834.944045] usb 3-1: new full-speed USB device number 17 using uhci_hcd

Update: now i do get data! thanks.

(at first thought not because was using tail -f but it was set for another baud, after setting to the right one i got my "A"s filling the screen)
