TILT!Audio

New firmware 1.28 is out: https://mega.nz/#!l4xyDI5I!qoBXKPpOlxKabubys3AqH6tNBpEhtj0eJvP5bU4uTSY

It has a few bugfixes and especially support for the port extender (with board rev 2.5f and newer)

To use extension port you simply can reuse the serialCmd field in the sound effect details. New 1.28 recognized a few additional commands: 
1. all commands for the serial media server (like before): PLAY, STOP und PLAYONEOF 
2. NEW commands for the port extender: PORT x ON, PORT x OFF oder PORTSEQ x n1 n2 n3 …

You can also combine both comamnd types in one, just use a colon as separator. X is the placeholder for the port number with the range 100-115 -> 16 outputs. The n1, n2 … values are timespans of milli seconds, in order to playback a sequence. The port pin then toggles on and off.

There is also a new settings page in the web ui, that allows for testing GPIOs and commands in general: 

With this testing page you can check and test your installation wihtout playing the actual sound effect.

I finally took the time this evening and put one of my spare TILT!Audio boards into my msf game. Took only a few minutes to replace and it plays very nice.

My msf has a few more mods like extra leds in backbox speakers, big color pin2dmd and also the whole gi is rgb. But to be honest the biggest thrill is always the new sound. Of course I replaced the speakers as well to get more volume and clearer sound.

Better Wifi Setup

If wifi is not configured in the beginning and TILT!Audio cannot get an IP address it creates it own Wifi hotspot named „TILTAUDIO“. As soon as you see this wifi network appearing on your computer just connect by using the passphrase „tiltaudio“.

Then open the web ui in your browser on http://192.168.42.1:31008/

If you want to include the TILT!Audio system in your home wifi navigate to „Wifi“. Choose your wifi network and enter your passphrase, press „Setup Wifi“ and finally Reboot.

This will reboot the TILT!Audio system and after it is up again, you should reach the web ui by simply http://tiltaudio:31008/ . If this doesn’t work you need to find out the ip address by checking your router for a new device.

10 Band Equalizer

There are a couple of new synthetic audio devices, that add some signal processing before hand over sound to the hifi DAC. One of them is a 1 band equalizer, that allows fine tuning your sound output for TILT!Audio.

You can listen to every sound from your sound set or choose one of the test sounds and then fine tune the sound exactly for your system.

The equalizer is a global fine tuning, that applies the same „curve“ to all sounds from TILT!Audio. Of course it is still possible to add a per sound increase or decrease of volume.

Bugfixes / Changes:

• Bugfix when loading altsound sound packs
• Change default to enable_i2s to true so it matches all newer shields.
• Added option to reboot from web ui as part of wifi setup
• Rename low level service to “tiltaudio”. When ssh to pi use “sudo systemctl start/stop tiltaudio” …
• Changes storage for “tmp settings” like sound set, volume and audio device to ta.ini file
• Start web UI even without sound.
• Bugfix: switch rotary support off, when i2s is on
