BobBurns / SPI-hello_eeprom.asm

Created December 10, 2014 23:48

demo assembly program using 25LC256 EEPROM with SPI

	;demo program to learn how the avr can talk to another device with SPI
	;in this case the 25LC256 eeprom
	;
	;based on the example code in c from Elliot Williams AVR Programming
	;this example writes a string to the eeprom and then read it into sram to be sent over USART
	;
	;compile with gavrasm SPI-hello_eeprom.asm
	;flash with avrdude -c avrisp -p m168 -P /dev/tty.useyourmodem -b 19200 -U flash:w:SPI-hello_eeprom.hex
	;
	;there are a couple extra convenience routines to use later

php websocket device server

	#!/usr/bin/php
	<?php
	/* websocket/device server program for raspberry pi
	* this program only deals with packets that are 125 bytes max
	* currently only one client can connect at a time. Maybe not a bad thing.
	* run as super user (for gpio access)
	* check out https://gist.github.com/BobBurns/6f83930912da4094f014 for the client html code

	* much of the juicy bits adapted from ghedipunk/PHP-Websockets
