Hi i need a key mapper I'm doing some tests the simpliest though most complex thing i could think of is doing a keyboard outputs from a amplitude + frequency from voltage through a transducer input to the A pins on my feather, A0 for single press A1 for continuous key such as shift backspace delete ctrl fn alt enter though i require a graph for amplitude also frequency sensing that also has a selector below it to set the senseing to a keyboard output, such as check boxes then a touchscreen button to press to accept the senseing data as whatto respond to output a keystroke from the voltage's frequency also amplitude from applied on the sensor Rp2040 feather 4884 I don't have a separate screen or wifi peripheral for it so it gotta run on my samsung galaxy s6 lite android tablet in developer mode through u.s.b. serial also o.t.g. adapter I opinion a .html interface to set the keys to specific input triggers on the board to interact with the .py on the board would be simplest unless other suggestions
