4 years ago There are certainly cleaner ways to do the integration, but if you just want to reuse the code you posted, you can do something like this:
#include <Control_Surface.h>
#include <Adafruit_MCP23017.h>
typedef void (*rotaryActionFunc)(bool clockwise, int id);
class RotaryEncOverMCP {
public:
RotaryEncOverMCP(Adafruit_MCP23017* mcp, byte pinA, byte pinB, rotaryActionFunc actionFunc = nullptr, int id = 0) {}
// ...
};
// --------------------------------------------------------------------------
USBMIDI_Interface midi;
Bank<3> bank(4);
Bankable::SingleAddress encAddresses[8] = {
{bank, 16},
{bank, 17},
{bank, 18},
{bank, 19},
{bank, 20},
{bank, 21},
{bank, 22},
{bank, 23},
};
void handler(bool clockwise, int id) {
MIDIAddress address = encAddresses[id].getActiveAddress();
RelativeCCSender::send(clockwise ? +1 : -1, address);
}
Adafruit_MCP23017 mcp;
RotaryEncOverMCP rotaryEncoders[] = {
{&mcp, 0, 1, handler, 0}, // Pins GPA0,GPA1, register with encAddresses id 0
{&mcp, 2, 3, handler, 1},
{&mcp, 4, 5, handler, 2},
// ...
};
IncrementDecrementSelector<3> selector = {bank, {2, 3}};
void setup() {
Control_Surface.begin();
// Initialize mcp here and attach interrupt
// see https://github.com/maxgerhardt/rotary-encoder-over-mcp23017/blob/master/examples/Interrupt/InterruptExample.cpp
}
void loop() {
Control_Surface.loop();
// Update mcp and rotaryEncoders here if interrupt occured
// see https://github.com/maxgerhardt/rotary-encoder-over-mcp23017/blob/master/examples/Interrupt/InterruptExample.cpp

I'have the code below, for use multiples MCP23017, with rotary encoders and switches, and work correctly, but i'm interested about the integration with your system and my code. I use an Arduino Mega, 16 Encoders, a fews MCPs and i like to use with my Presonus Studio One DAW, I would like to use 8 volumen, and 8 pan with the encoders. And integrate with your banks, etc.
