Download and Install TouchOSC from either the Apple App Store for iOS or Google Play store for Android.
MEMENTO Layout
Download the TouchOSC layout file linked in the button below and uncompress it. You can then transfer it to your phone or tablet -- for example, on iOS an iCloud shared folder can be used.
Open Document
In TouchOSC, tap the Editor Panel icon.
Then, scroll the toolbar to reveal the Open Document icon.
Tap it and browse for the MEMENTO_remote file.
Tap the Import button, this will open the layout into the TouchOSC editor.
A Comment popup will open, tap OK.
You can now close the Editor Panel by tapping the icon shown.
Connections
Tap the link icon to open the Connections page, this is where we'll establish UDP settings for the MEMENTO's server.
IP Address
When you reset or power on the MEMENTO, look for the IP address listed at the bottom of the screen. This screen will pause for ten seconds so you can write down that IP address. This is the address you'll use on the next step in TouchOSC to fill in the Host settings.
Tap the OSC button.
Check the box for Connection 1, select UDP from the dropdown menu, and then fill in the Host address of your MEMENTO (this is printed in the REPL serial output when the MEMENTO first connects to your WiFi access point). In my case it is 192.168.1.57 but this will most likely be different for you depending on your network.
Fill in the Send Port address as 8000. Then, tap Done to return to the editor.
Control Surface View
Scroll the top toolbar until you see the triangle "play" button. This launches the Control Surface view, which is the interaction mode of TouchOSC.
Press the big red button to snap the shutter on the camera -- remotely! This will send the OSC message over WiFi to tell the MEMENTO to take a picture (or start recording a GIF).
You can now also tap the focus button to have the camera focus on the center frame subject.
Tap any of the mode buttons at the bottom of the screen to pick among JPEG, GIF, Gameboy, and Stop motion modes.
The MEMENTO remote layout has two pages, which are selected with the tabs named remote and settings. Tap the settings tab now.
Settings
The resolution page is broken into three columns.
In the Resolution column you can pick any of the available pixel resolutions.
In the LEDs column you can pick NeoPixel colors and adjust the brightness with the fader.
In the Effects column you can pick among any of the available effects.
To get back to the snapshot screen, tap the remote tab.
Any time you want to leave Control Surface view and return to the editor, tap the circle in the upper right corner of the screen.
