I pretty much can't parse your questions (grammatically).

HI,

 if arduino can output 40 Ma per pin ( http://playground.arduino.cc/Main/ArduinoPinCurrentLimitations )

 How olinuxino maxi with 12v 1.5 A can outup per pin ( gpio per exemple )

 I think is more than a arduino ?

 Its for ( http://www.mon-club-elec.fr/pmwiki_mon_club_elec/pmwiki.php?n=MAIN.ArduinoInitiationLedsDiversTestRubanRVB )

 Yes my english is very poor :), no problem for read but speak and write....

 
Best Regards

The amount a uC pin can source or sink is in the uC datasheet with total limit etc.

(The Arduino data you linked to is the equivalent from an Atmel data sheet.)

So, just refer to the iMX233 data sheet.

imx233 pins can be configured in software (linux pinctrl driver) to use a drive strength of 4mA, 8mA or 12mA.

Hi,

   Yes i read the 1612 pages of imx233 data sheet. 8)  Thk JohnS, good is to know some data sheet.

   Lambda you are ok, 4mA, 8mA or 12mA 
   
   less of arduino. ( no good for led ruban, use mosfet too )

   thk for all you re reply

   I return to my ir emiter problem

Best Regards

Have you some link for  uart (olinuxino) how to program ? ( c, bash ?)

Best Regards

hi,

  simple question :   How i can send data over the TXD pin on UEXT of imx233 maxi

  i see /dev/ttyAPP0 but cat "booooooooo" > /dev/ttyAPP0 no work with my ir emiter...  :-X


Best Regards

IIRC when I tried to output some data via echo to /dev/ttyAPP0 I had to setup the tty with some tool like stty or setserial. I don't remember the details: usually I use microcom or busybox-microcom these days.

HTH,
