# nec_ir_remote_receiver_irq_pico

A simple, IRQ-based implementation of the IR NEC receiver protocol in C using the Raspberry Pi Pico SDK.

# How to install the module (for beginners)

The minimal way of adding this module to your CMake project is by downloading the `ir_rx_irq.c` and `ir_rx_irq.h` files

and placing them in the same folder as your main source.

From there, you have to add the files inside `add_executable`. For example:

```cmake

add_executable(my_project

        main.c

        ir_rx_irq.c

        ir_rx_irq.h

        )

```

# Usage

Check `example.c` for a basic starting point.

```c

// type = 1 if it's a normal command, type = 2 if it's a repeat command 

// (sent by holding the button down for a long time)

// This function will be called when you press a button on the remote

// and the sensor receives it correctly.

void callback_ir (uint16_t address, uint16_t command, int type) {

    printf("Got 0x%04X 0x%04X %d\n", address, command, type);

}

int main() {

    ...

    // This is all you do.

    init_ir_irq_receiver(YOUR_GPIO_PIN, &callback_ir);

    ...

}

```
