Hold B2 for 2 seconds - Jump 10 folders or tracks backwards
During power up:
----------------
Hold B0 + B1 + B2 - Erase all eeprom contents (resets stored progress and preferences)
ir remote:
==========
If an ir receiver (like TSOP38238 or similar) is connected to pin 5, you can also use
an ir remote to remote control TonUINO. The remote needs at least seven buttons to be
able to support all functions. This feature can be enabled by uncommenting the
'#define IRREMOTE' below.
Down below you can hard code (multiple sets of) code mappings for remotes which will
always be recognized. In addition to these hard coded remotes, you can learn in one
additional remote using the parents menu, which is then stored in EEPROM.
There is one function, currently only available with the ir remote: Box lock.
When TonUINO is locked, the buttons on TonUINO as well as the nfc reader are disabled
until TonUINO is unlocked again. Playback continues while TonUINO is locked and
you are still able to control TonUINO using the ir remote (great for parents).
During idle:
------------
center - toggle box lock
menu - enter parents menu
During playback:
----------------
center - toggle box lock
play/pause - toggle playback
up / down - volume up / down
left / right - previous / next track ((v)album, (v)party and story book mode)
menu - reset progress to track 1 (story book mode)
menu - single track repeat (all modes, except story book mode)
During parents menu:
--------------------
center - announce current option
play/pause - confirm selection
up / down - next / previous option
left / right - jump 10 options backwards / forward
menu - cancel
During nfc tag setup mode:
--------------------------
center - announce current folder, mode or track number
play/pause - confirm selection
up / down - next / previous folder, mode or track
left / right - jump 10 folders or tracks backwards / forward
menu - cancel
pin code:
=========
The complete erase of the eeprom contents (hold vol-, play/pause, vol+ during startup)
as well as the parents menu can be secured with a pin code of variable length. It is
defined (and can be changed) in the configuration section below, the default pin code is:
===> play/pause, vol-, vol+, play/pause <===
Once the pin code entry is triggered, you have (by default) 10s to enter the pin code
before it times out. It repeats when entered incorrectly. See status led section
for information about visual feedback. This feature can be enabled by uncommenting
the '#define PINCODE' below.
status led(s):
==============
There are two options for a status led (which are mutually exclusive!):
1) Connect a vanilla led to pin 6 and uncomment the '#define STATUSLED' below.
TonUINO will signal various status information, for example:
- Pulse slowly when TonUINO is idle.
- Solid when TonUINO is playing a title.
- Blink every 500ms when interactive in menus etc.
- Blink every 100ms if the LOWVOLTAGE feature is active and the battery is low.
- Burst 4 times when TonUINO is locked and 8 times when unlocked.
- Burst 4 times when repeat is activated and 8 times when deactivated.
There are some more signals, they try to be intuitive. You'll see.
2) Connect one (or even several) ws281x rgb led(s) to pin 6 and uncomment
the '#define STATUSLEDRGB' below. TonUINO will signal various status information
in different patterns and colors, for example:
- Pulse slowly green when TonUINO is idle.
- Solid green when TonUINO is playing a title.
- Blink yellow every 500ms when interactive in menus etc.
- Blink red every 100ms if the LOWVOLTAGE feature is active and the battery is low.
- Burst 4 times red when TonUINO is locked and 8 times green when unlocked.
- Burst 4 times white when repeat is activated and 8 times white when deactivated.
- Burst 8 times magenta when the track in story book mode is reset to 1.
There are some more signals, they try to be intuitive. You'll see.
For the vanilla led basically any 5V led will do, just don't forget to put an appropriate
resistor in series. For the ws281x led(s) you have several options. Stripes, single
neo pixels etc. The author did test the fuctionality with an 'addressable Through-Hole 5mm RGB LED'
from Pololu [1]. Please make sure you put a capacitor of at least 10 uF between the ground
and power lines of the led and consider adding a 100 to 1k ohm resistor between pin 6
and the led's data in. In general make sure you have enough current available (especially if
you plan more than one led - each takes up to 60mA!) and don't source the current for the led(s)
from the arduino power rail! Consult your ws281x led vendors documentation for guidance!
The ammount of ws281x led(s) as well as the max brightness can be set in the configuration
section below. The defaults are: One led and 20% brightness.

cubiekid:
=========
If you happen to have a CubieKid case and the CubieKid circuit board, this firmware
supports both shutdown methods. The inactivity shutdown timer is enabled by default,
the shutdown due to low battery voltage (which can be configured in the shutdown
section below) can be enabled by uncommenting the '#define LOWVOLTAGE' below.
The CubieKid case as well as the CubieKid circuit board, have been designed and developed
by Jens Hackel aka DB3JHF and can be found here: https://www.thingiverse.com/thing:3148200
pololu switch:
==============
If you want to use a pololu switch with this firmware the shutdown pin logic needs
to be flipped from HIGH (on) -> LOW (off) to LOW (on) -> HIGH (off). This can be done
by uncommenting the '#define POLOLUSWITCH' below.
data stored on the nfc tags:
============================
On MIFARE Classic (Mini, 1K & 4K) tags:
---------------------------------------
Up to 16 bytes of data are stored in sector 1 / block 4, of which the first 9 bytes
are currently in use:
13 37 B3 47 01 02 04 10 19 00 00 00 00 00 00 00

On MIFARE Ultralight / Ultralight C and NTAG213/215/216 tags:
-------------------------------------------------------------
Up to 16 bytes of data are stored in pages 8-11, of which the first 9 bytes
are currently in use:
8 13 37 B3 47 - magic cookie to recognize that a card belongs to TonUINO (by default 0x13 0x37 0xb3 0x47)
9 01 02 04 10 - version, folder, playback mode, single track / start strack

FM Radio - TEA5767:
===================
This feature can be enabled by uncommenting the "define FMRADIO" below.
Connect TEA5767 fm radio module pins as follows:
SLC (radio) => A5 (Arduino)
SDA (radio) => A4 (Arduino)
To identify radio tags, a dedicated magic cookie (first 4 bytes) has to be
set accordingly. The version number (fifth byte) has to be set to 0x01.
Frequency is stored in bytes 6 and 7. All other bytes are cleared (set to 0x00).
13 37 70 01 01 5C 02 00 00 00 00 00 00 00 00 00
----------- -- -- --
| | | |
| | | + frequency fractional
| | + frequency integer
| + version (currently always 0x01)
+ magic cookie to recognize that a card belongs to TonUINO
For those who need a short oneliner to convert radio station frequency to RFID data:
echo -n "Radio station frequency in MHz (e.g. 92.2): "; read -r freq; echo -n "Write the following data to your RFID card: "; printf "13 37 70 01 01 %0.2X %0.2X 00 00 00 00 00 00 00 00 00\n" ${freq%.*} ${freq#*.}
To create a special RFID tag that tunes in the next available station (search card),
set frequency integer and fractional to 0. Search will start at 87 MHz, end at 108 MHz
and wrap around, if the upper band limit is reached.
It's also possible to switch between stations using previous/next buttons,
while the radio is active and playing/unmuted.
