Spin Semiconductor

To close the thread, I got it working perfectly. - Program selection pins connected through pull-up 20k resistors to V+ - A 1->8 rotary switch selects a program. Its input pin to ground. - Each output pin is connected, through low-signal diodes, to a sub-group of program pins Presence of a diode in ...

I think the variable is if you know a bit of DSP or not.

If you have DSP basics, using an example and understanding it with the manual opened works great!

If are absolutely new to DSP, a first order lowpass filter is a great starting point.

Thanks!

You used, like I'm doing, pull-up Rs and diodes to gnd, right? (Not the opposite, pull-down Rs and contacts to V+, like now I can see on the dev-board schematics).

Hi all! First post

I wonder what switching thresholds are for program selection pins.
This is because I'm driving them through some diodes, so "tie to ground" is still about +0.5V.

Should it work?

Why diodes: to be able to select combinations through a single deck 1x8 rotary switch.
