OK, I have searched and searched, but I can't seem to find any good resources for the project I am wanting to do, so here it is.
I want to build a custom MIDI foot switcher which will have 18 SPST soft touch foot switches that will send ONLY program changes to an effects processor. It needs to have a BANK UP and BANK DOWN button as well.
HERE'S WHERE IT GETS TRICKY!
I want 2 independent 7" color graphic displays. The first will display pictures with text (i.e. button #, midi patch number and preset name) and will correspond to the foot switch that is active. Each foot switch will have an indicator led. The 2nd display will be for a dedicated guitar tuner display, but will only be active when the DPDT switch (to activate the tuner circuit) is pressed. Also, upon power-up, I want the displays to raise up to an angle from a recessed resting location, and return to the resting position up power down. I will use a Highly Liquid DIY Instant MIDI board, and plan on having an Arduino Leonardo to run each display and servo. One will handle the leds and the other will handle the tuner.
I cant figure out how to connect the displays, and I cant figure out how to get the tuner circuit to display (in a usable format) on the display. I am a newby and could REALLY USE SOME HELP!!
