This directory is intended for the project specific (private) libraries.
PlatformIO will compile them to static libraries and link to executable file.
The source code of each library should be placed in separate directory, like
"lib/private_lib/[here are source files]".
For example, see how can be organized `Foo` and `Bar` libraries:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) http://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- readme.txt --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
Then in `src/main.c` you should use:
#include <Foo.h>
#include <Bar.h>
// rest H/C/CPP code
PlatformIO will find your libraries automatically, configure preprocessor's
include paths and build them.

* Interrupt and PWM utilities for 16 bit Timer1 on ATmega168/328
* Original code by Jesse Tane for http://labs.ideo.com August 2008
* Modified March 2009 by Jérôme Despatis and Jesse Tane for ATmega328 support
* Modified June 2009 by Michael Polli and Jesse Tane to fix a bug in setPeriod() which caused the timer to stop
* Modified June 2011 by Lex Talionis to add a function to read the timer
* Modified Oct 2011 by Andrew Richards to avoid certain problems:
* - Add (long) assignments and casts to TimerOne::read() to ensure calculations involving tmp, ICR1 and TCNT1 aren't truncated
* - Ensure 16 bit registers accesses are atomic - run with interrupts disabled when accessing
* - Remove global enable of interrupts (sei())- could be running within an interrupt routine)
* - Disable interrupts whilst TCTN1 == 0. Datasheet vague on this, but experiment shows that overflow interrupt
* flag gets set whilst TCNT1 == 0, resulting in a phantom interrupt. Could just set to 1, but gets inaccurate
* at very short durations
* - startBottom() added to start counter at 0 and handle all interrupt enabling.
* - start() amended to enable interrupts
* - restart() amended to point at startBottom()
* Modiied 7:26 PM Sunday, October 09, 2011 by Lex Talionis
* - renamed start() to resume() to reflect it's actual role
* - renamed startBottom() to start(). This breaks some old code that expects start to continue counting where it left off

// From what I have seen, the only time we go over 8-bits is the 'space'
// on the end which creates the lead-out/inter-code gap. Assuming I'm right,
// we can code this up as a special case and otherwise halve the size of our
// data!
// Ignoring the first four values (the config data) and the last value
// (the lead-out), if you find a protocol that uses values greater than 00fe
// we are going to have to revisit this code!
//
//
// So, the 0th byte will be the carrier frequency in Khz (NOT Hz)
// " 1st " " " " length of the "once" code
// " 2nd " " " " length of the "repeat" code
//
// Thereafter, odd bytes will be Mark lengths as a multiple of USECPERTICK uS
// even " " " Space " " " " " " "
//
// Any occurence of "FF" in either a Mark or a Space will indicate
// "Use the 16-bit FF value" which will also be a multiple of USECPERTICK uS
//
//
// As a point of comparison, the test code (prontoTest[]) is 520 bytes
// (yes, more than 0.5KB of our Arduino's precious 32KB) ... after conversion
// to pronto hex that goes down to ((520/5)*2) = 208 bytes ... once converted to
// our format we are down to ((208/2) -1 -1 +2) = 104 bytes
//
// In fariness this is still very memory-hungry
// ...As a rough guide:
// 10 codes cost 1K of memory (this will vary depending on the protocol).
//
// So if you're building a complex remote control, you will probably need to
// keep the codes on an external memory device (not in the Arduino sketch) and
// load them as you need them. Hmmm.
//
// This dictates that "Oscillated Pronto Codes" are probably NOT the way forward
//
// For example, prontoTest[] happens to be: A 48-bit IR code in Denon format
// So we know it starts with 80/40 (Denon header)
// and ends with 10/aa6 (Denon leadout)
// and all (48) bits in between are either 10/10 (Denon 0)
// or 10/30 (Denon 1)
// So we could easily store this data in 1-byte ("Denon")
// + 1-byte (Length=48)
// + 6-bytes (IR code)
// At 8-bytes per code, we can store 128 codes in 1KB or memory - that's a lot
// better than the 2 (two) we started off with!
//
// And serendipitously, by reducing the amount of data, our program will run
// a LOT faster!
//
// Again, I repeat, even after you have spent time converting the "Oscillated
// Pronto Codes" in to IRremote format, it will be a LOT more memory-hungry
// than using sendDenon() (or whichever) ...BUT these codes are easily
// available on the internet, so we'll support them!

/*
Assuming the protocol we are adding is for the (imaginary) manufacturer: Shuzu
Our fantasy protocol is a standard protocol, so we can use this standard
template without too much work. Some protocols are quite unique and will require
considerably more work in this file! It is way beyond the scope of this text to
explain how to reverse engineer "unusual" IR protocols. But, unless you own an
oscilloscope, the starting point is probably to use the rawDump.ino sketch and
try to spot the pattern!
Before you start, make sure the IR library is working OK:
# Open up the Arduino IDE
# Load up the rawDump.ino example sketch
# Run it
Now we can start to add our new protocol...
1. Copy this file to : ir_Shuzu.cpp
2. Replace all occurrences of "Shuzu" with the name of your protocol.
3. Tweak the #defines to suit your protocol.
4. If you're lucky, tweaking the #defines will make the default send() function
work.
5. Again, if you're lucky, tweaking the #defines will have made the default
decode() function work.
You have written the code to support your new protocol!
Now you must do a few things to add it to the IRremote system:
1. Open IRremote.h and make the following changes:
REMEMEBER to change occurences of "SHUZU" with the name of your protocol
A. At the top, in the section "Supported Protocols", add:
#define DECODE_SHUZU 1
#define SEND_SHUZU 1
B. In the section "enumerated list of all supported formats", add:
SHUZU,
to the end of the list (notice there is a comma after the protocol name)
C. Further down in "Main class for receiving IR", add:
//......................................................................
#if DECODE_SHUZU
bool decodeShuzu (decode_results *results) ;
#endif
D. Further down in "Main class for sending IR", add:
//......................................................................
#if SEND_SHUZU
void sendShuzu (unsigned long data, int nbits) ;
#endif
E. Save your changes and close the file
2. Now open irRecv.cpp and make the following change:
A. In the function IRrecv::decode(), add:
#ifdef DECODE_NEC
DBG_PRINTLN("Attempting Shuzu decode");
if (decodeShuzu(results)) return true ;
#endif
B. Save your changes and close the file
You will probably want to add your new protocol to the example sketch
3. Open MyDocuments\Arduino\libraries\IRremote\examples\IRrecvDumpV2.ino
A. In the encoding() function, add:
case SHUZU: Serial.print("SHUZU"); break ;
Now open the Arduino IDE, load up the rawDump.ino sketch, and run it.
Hopefully it will compile and upload.
If it doesn't, you've done something wrong. Check your work.
If you can't get it to work - seek help from somewhere.
If you get this far, I will assume you have successfully added your new protocol
There is one last thing to do.
1. Delete this giant instructional comment.
2. Send a copy of your work to us so we can include it in the library and
others may benefit from your hard work and maybe even write a song about how
great you are for helping them! :)
Regards,
BlueChip
