Created July 2, 2014 20:31

First attempt at a driver for the MAX3421E USB Host


	// -----------------------------------------------------------------------------
	// USB Host Shield pinouts
	//
	// 1- CS (not sure if it's active high/low)
	// 2- MISO
	// 5- SCLK
	// 7- MOSI
	// 8- RESET (also not sure about active high/low)
	// 9- Interrupt (not sure if this is useful for anything)

blindman2k / newblank.agent.nut

Last active August 29, 2015 14:02

This New Blank model is designed to allow simple HTTP GET commands to read and write the imp and its pins.

	/*
	* These are the currently supported commands (URLs)
	*
	* /device/hardware/pinX/configure (DIGITAL_OUT, DIGITAL_IN, ANALOG_OUT, ANALOG_IN, PWM_OUT)
	* /device/hardware/pinX/read
	* /device/hardware/pinX/write
	*
	* /device/hardware/X (all hardware.* commands like lightlevel, voltage, etc)
	*
	* /device/imp/X (all imp.* commands that take no parameters like getssid, rssi, etc)

blindman2k / override.nut

Last active August 29, 2015 14:01

Overriding imp's built-in objects can be fun :)

	// This is a really simple, reusable wrapper for any internal object to turn it into a class.
	// For memory and performance reasons, the built-in classes are not real classes so can't
	// be extended in the normal way.
	class impWrapper {
	_wrapped = null;

	constructor(wrapped) {
	_wrapped = wrapped;
	}

blindman2k / vformat.nut

Last active August 29, 2015 14:01

vformat gives you the same functionality is format() but allows you to pass in parameters as an arbitrary length array.

	function vformat(fmt,...) {
	local args = [this,fmt];
	if (typeof(vargv[0]) == "array") {
	vargv = vargv[0];
	}
	args.extend(vargv);
	return format.acall(args);
	}

blindman2k / neo_neopixel.device.nut

Created May 14, 2014 17:42

This is a new Neopixel class designed specifically for rectangular X/Y coordinate systems but still works fine for linear strips. Note the function names have changed.

	class NeoPixels {

	// when instantiated, the neopixel class will fill this array with blobs to
	// represent the waveforms to send the numbers 0 to 255. This allows the blobs to be
	// copied in directly, instead of being built for each pixel - which makes the class faster.
	bits = null;

	// Like bits, this blob holds the waveform to send the color [0,0,0], to clear pixels faster
	clearblob = null;

blindman2k / test_scanwifinetworks.device.nut

Created May 9, 2014 21:44

Uses an impeeduino to test the imp.scanwifinetworks() while in offline mode.


	// Pin 2 is the red LED
	ACTIVITY <- hardware.pin2;
	ACTIVITY.configure(DIGITAL_OUT);
	ACTIVITY.write(1);

	// Pin 8 is the orange LED
	LINK <- hardware.pin8;
	LINK.configure(DIGITAL_OUT);
	LINK.write(1);
