Code Issues Releases Activity

Remove sam platform from IDE repo

Browse Source 
Refer to https://github.com/arduino/ArduinoCore-sam for further development.
All the tagged issues will be moved to the new repo
PRs which only apply to SAM platform will need to be recreated instead

* Udp.cpp: Library to send/receive UDP packets.
*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.
* For more information, see http://www.cafeaulait.org/course/week12/35.html

# Hey Emacs, this is a -*- makefile -*-
#----------------------------------------------------------------------------
# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.
# >> Modified for use with the LUFA project. <<
#
# Released to the Public Domain
#
# Additional material for this makefile was written by:
# Peter Fleury
# Tim Henigan
# Colin O'Flynn
# Reiner Patommel
# Markus Pfaff
# Sander Pool
# Frederik Rouleau
# Carlos Lamas
# Dean Camera
# Opendous Inc.
# Denver Gingerich
#
#----------------------------------------------------------------------------
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make coff = Convert ELF to AVR COFF.
#
# make extcoff = Convert ELF to AVR Extended COFF.
#
# make program = Download the hex file to the device, using avrdude.
# Please customize the avrdude settings below first!
#
# make dfu = Download the hex file to the device, using dfu-programmer (must
# have dfu-programmer installed).
#
# make flip = Download the hex file to the device, using Atmel FLIP (must
# have Atmel FLIP installed).
#
# make dfu-ee = Download the eeprom file to the device, using dfu-programmer
# (must have dfu-programmer installed).

# make flip-ee = Download the eeprom file to the device, using Atmel FLIP
# (must have Atmel FLIP installed).
#
# make doxygen = Generate DoxyGen documentation for the project (must have
# DoxyGen installed)
#
# make debug = Start either simulavr or avarice as specified for debugging,
# with avr-gdb or avr-insight as the front end for debugging.
#
# make filename.s = Just compile filename.c into the assembler code only.
#
# make filename.i = Create a preprocessed source file for use in submitting
# bug reports to the GCC project.
#
# To rebuild project do "make clean" then "make all".
#----------------------------------------------------------------------------
# MCU name(s)
# Since the ATMEGA8U2 part is not directly supported by the current

# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency in Hz. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
#
# This will be an integer division of F_CLOCK below, as it is sourced by
# F_CLOCK after it has run through any CPU prescalers. Note that this value
# does not *change* the processor frequency - it should merely be updated to
# reflect the processor speed set externally so that the code can use accurate
# software delays.

# Input clock frequency.
# This will define a symbol, F_CLOCK, in all source code files equal to the
# input clock frequency (before any prescaling is performed) in Hz. This value may
# differ from F_CPU if prescaling is used on the latter, and is required as the
# raw input clock is fed directly to the PLL sections of the AVR for high speed
# clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
# at the end, this will be done automatically to create a 32-bit value in your
# source code.

To setup the project and upload the Arduino usbserial application firmware to an ATMEGA32U2 using the Arduino USB DFU bootloader:
1. unpack the source into LUFA's Projects directory
2. set ARDUINO_MODEL_PID in the makefile as appropriate
3. do "make clean; make"
4. put the 32U2 into USB DFU mode:
4.a. assert and hold the 32U2's RESET line
4.b. assert and hold the 32U2's HWB line
4.c. release the 32U2's RESET line
4.d. release the 32U2's HWB line
5. confirm that the board enumerates as "ATmega32u2"
6. do "make dfu" (OS X or Linux - dfu-programmer must be installed first) or "make flip" (Windows - Flip must be installed first)
Check that the board enumerates as "Arduino Mega 2560".
Test by uploading a new Arduino sketch from the Arduino IDE.

Digital Pot Control
This example controls an Analog Devices AD5206 digital potentiometer.
The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
A - connect this to voltage
W - this is the pot's wiper, which changes when you set it
B - connect this to ground.
The AD5206 is SPI-compatible,and to command it, you send two bytes,
one with the channel number (0 - 5) and one with the resistance value for the
channel (0 - 255).
The circuit:
* All A pins of AD5206 connected to +5V
* All B pins of AD5206 connected to ground
* An LED and a 220-ohm resisor in series connected from each W pin to ground
* CS - to digital pin 10 (SS pin)
* SDI - to digital pin 11 (MOSI pin)
* CLK - to digital pin 13 (SCK pin)
