Zwilk Posted September 25, 2014 Share Posted September 25, 2014 (edited) Maybe I first have to mention I am a complete layman in programming. I have done HTML5 and CSS3, but I understand this is complete different. A while ago I was asked to use a Teensy 2.0 as USB emulator. The intention was to shut Windows down with this emulator. My task was to write a code by using the following scan codes, found on www.win.tue.nl. Set-1 make/brake Set-2 make/brake Power e0 5e / e0 de e0 37 / e0 f0 37 Sleep e0 5f / e0 df e0 3f / e0 f0 3f Wake e0 63 / e0 e3 e0 5e / e0 f0 5e So on the internet I found AutoIt when I searched for keystrokes. My question is: how can I use AutoIt to simulate the power key? Is there a possibility to use the above called information to shut down a Windows PC? I hope someone has a solution to help me.

javiwhite Posted September 25, 2014 Share Posted September 25, 2014 (edited) Hi Zwik, welcome to the AutoIT forums if you're looking to shutdown the pc, you could just use a hidden command prompt to achieve this: run(@comspec & " /c shutdown /s /t 0","",@SW_HIDE) the @COMSPEC is an AutoIT macro (it is the directory to cmd, so AutoIT runs command prompt) the /c is a cmd parameter meaning execute this code the rest is command line syntax for the shutdown command (/s is local, /t is the time in which to shutdown, 0 being immediately) the second parameter of the run function is the working directory for the program being run. The third and final parameter used "@SW_HIDE" is the AutoIT macro for hiding a window, Meaning the cmd won't pop up on the screen. Hopefully this helps you acheive what you're after? I've attempted to go into detail, but if you need further explanation, Just let me know? Many Thanks Javi EDIT: Just re-read your original request, If you're required to use those codes, then I'm afraid I don't know how to achieve this in AutoIT. Hopefully one of the more experienced coders on here can lend a hand Edited September 25, 2014 by javiwhite give a man an application, and he'll be frustrated for the day, Teach him how to program applications and he'll be frustrated for a lifetime.

Moderators JLogan3o13 Posted September 25, 2014 Moderators Share Posted September 25, 2014 @javiwhite, why would you suggest the OP go through all that rather than just using the native Shutdown() command in AutoIt? @zwilk, not being familiar with Teensy, how are you presented with those codes (pop up display, output to log file, etc.)? That will determine how you capture them and then make your action decisions. "Profanity is the last vestige of the feeble mind.

javiwhite Posted September 25, 2014 Share Posted September 25, 2014 @javiwhite, why would you suggest the OP go through all that rather than just using the native Shutdown() command in AutoIt? All that? It still equates to one line of code, and provides the user with greater customisation over the shutdown command. (Timeouts, Remote machines shutdowns etc...) I wasn't aware of the native Shutdown() command, And after reading the syntax, I still wouldn't have suggested it for the aforementioned reasons... But there's always more than one way to skin a cat I suppose. give a man an application, and he'll be frustrated for the day, Teach him how to program applications and he'll be frustrated for a lifetime.

Kovacic Posted September 25, 2014 Share Posted September 25, 2014 Pretty sure Teensy is arduino based, try this: '?do=embed' frameborder='0' data-embedContent>> C0d3 is P0etry( ͡° ͜ʖ ͡°) Link to comment Share on other sites More sharing options...
Zwilk Posted September 29, 2014 Author Share Posted September 29, 2014 @javiwhite First, thank you for the fast reply. As you say, I have to use the above called scan codes. But if I want to use the @COMSPEC macro, can I copy this line 1:1 to the Arduino IDE? Because the Arduino uses C++... @JLogan3o13 Thanks for the reply! I haven't got these codes by myself so I do not know how these are presented. I found them on win.tue.nl. As far as I understand the keyboard generate these codes when pressed(make) a key and send them to the PC. When the button is released(brake), the keyboard sends a new scan code. Because there are keyboards available who have power/sleep/wake buttons I thought is would be simple. Just use one of the following lines and put a scan code in the parentheses. Serial.println(number); Serial.println(number, DEC); Serial.println(number, HEX); Serial.println(number, OCT); Serial.println(number, BIN); Serial.println(number, BYTE); Serial.println(3.14); Keyboard.press(KEY); Keyboard.release(KEY); But unfortunately it is not that easy. Is it even possible because not all keyboards have these buttons? /Zwilk Link to comment Share on other sites More sharing options...
