Ordinarily, it's just a GPIO you can use with digitalRead() etc. in order to influence your program flow. Its special semantics are:</p> <p>1) Shortly _after_ pressing RESET, while the bootloader is running, pressing it will cause entry into perpetual bootloader mode.<br /> 2) _When_ RESET is released, if BUT is also pressed, Maple enters into serial bootloader mode.</p> <p>edit: removed "digital" in reference to pins, since that's an Arduino thing </p> http://forums.leaflabs.com/topic.php?id=535#post-2798 Mon, 22 Nov 2010 23:49:20 +0000 josheeg 2798@http://forums.leaflabs.com/ <p>So that button not the reset one I should not have programmed using the maple ide and arduino code to do things ?<br /> So it does not go to the headers but I can use it to lets say push to have the loop go down path b. </p> http://forums.leaflabs.com/topic.php?id=535#post-2797 Mon, 22 Nov 2010 21:20:18 +0000 soundcyst 2797@http://forums.leaflabs.com/ <p>yes, boot0 is pulled down to ground, and the button (labeled BUT) causes that signal to be pulled high (for changing the boot configuration when resetting), but that's not connected to digital 13, nor is it broken out in the headers.</p> <p>digital 13 is connected to PA5. </p> http://forums.leaflabs.com/topic.php?id=535#post-2789 Mon, 22 Nov 2010 13:35:30 +0000 josheeg 2789@http://forums.leaflabs.com/ <p>on pin boot0 there is a pull down resistor a pull to power supply switch? is that corect and digital pin 13? </p>
