cs-midi

A standalone pico-sdk extraction of tttapa/Control-Surface (GPL-3.0).

cs-midi provides the core MIDI element system, BLE MIDI transport, banks, selectors, and the declarative Control_Surface singleton for use with the Raspberry Pi Pico SDK and the CYW43 radio module (BTstack BLE backend).

Getting Started

#include "pico/stdlib.h"
#include "pico/cyw43_arch.h"
#include <cs_midi.h>

using namespace cs;

BluetoothMIDI_Interface midi;

NoteButton button {5, {MIDI_Notes::C[4], Channel_1}};

int main() {
    stdio_init_all();
    if (cyw43_arch_init()) return 1;
    Control_Surface.begin();
    while (true) {
        Control_Surface.loop();
        sleep_ms(1);
    }
}

Differences from Control Surface

• #include <cs_midi.h> replaces #include <Control_Surface.h>
• cs::BluetoothMIDI_Interface replaces USBMIDI_Interface
• Standard main() with cyw43_arch_init() replaces Arduino setup()/loop()
• All types live in the cs:: namespace
• No MCU:: namespace — use raw CC numbers or MIDI_CC:: constants
