Hi All,<br><br>I apologie if this is off-topic. Please let me know if you think it is.<br><br>I have been working on my arduino-based pedal, and im faced with a peculiar problem right now. I&#39;m using 8 digital inputs ( 6 on the first socket of the board, inputs 2 through 8, and 2 on the second digital socket, inputs 9 and 10). The first 6 inputs work perfectly, but when i want to use any of the last two inputs (9 and 10), i have to trigger them twice before they start working. Then i&#39;m faced with the exact same problem when i get back to the first 6 inputs. I am pretty sure that i used the very same wiring for all 8 inputs.<br>
<br>So... I thought that maybe this could be a problem with firmata or pduino (no offense, Hans!). I have been spending the last hour trying to write a simple program in the arduino software in order to print in serial monitor the values of my digital inputs. <br>
<br>Now my question... Is the arduino software just really really bad? Or was it just not designed to work on an ubuntu machine? It is randomly very slow at start-up, it randomly disables the serial port menu in Tools, it randomly decides to prevent me from uploading the program in the board, or warns me that serial port dev/ttyACM0 is already in use, or can&#39;t be found. The fact that i unplug and replug the board, or change the usb port, or restart the software doesn&#39;t seem to make any difference. <br>
<br>This is beginning to look more like witchcraft than computer science to me.<br><br>Please help me, or i&#39;ll teach it how to fly out my window.<br><br>Thank you.<br><br>Pierre<br><br>
