Analog potentiometers as devices for entering values are not suitable for this project since I cannot seem to get steady readings. The four potentiometers will therefore be used as PERFORMANCE CONTROLLERS controlling the "tweakable" parameters like filter frequency, oscillator frequency etc.
The rotary encoder will take over the role as data entry device. One click to enter, change value, then one click to exit.
So now I'll have to come up with a new UI.
Also the five UARTS I mentioned in a previous post is not possible on the SIGNAL modules since UART 2 pins are used for the TFT. Bummer...
