Hello! First off, I'm a software engineer. I don't do hardware! As you can see, I can't even fade a LED... I am trying to run the "Fading" example project as provided by the Arduino IDE, https://www.arduino.cc/en/Tutorial/Fading Using the UDOO documentation showing the Arduino pin out, https://www.udoo.org/docs-x86/Arduino_101_(Intel_Curie)/Pinout.html, I connect my LED & resistor between pins identified as GND and PWM9 in the PWM section as shown on the UDOO pin out diagram. As soon as I make the connection, the entire module (including the x86) resets. I guess that I shouldn't make that connection and I should stick to software! If I make the LED connection between GND and LED as identified on the UDOO image, I can control the LED using the digitalWrite function without any problem. My question is, the pin-out shown in the UDOO documentation: is different to the pin out shown in the Fading guide on the Arduino site: Are the UDOO pins supposed to be the same as the Arduino pins? Have I missed some UDOO documentation somewhere which says "UDOO pins are the same as Arduino pins except for the following..."? Regards, Chris
If you are using pin 9 then that is the same pin that can trigger on/off the sleep mode of the braswell side if the Udoo X86. If you do not want this, set the power options off in the uefi/bios https://www.udoo.org/docs-x86/Ardui...aswell_Power_Management_From_Arduino_101.html
Hi waltervl, Disabling the Curie Power Management in the BIOS as described in the link you posted fixed my problem. Thank you.
