A simple, IRQ-based implementation of the IR NEC receiver protocol in C using the Raspberry Pi Pico SDK.
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:
add_executable(my_project
main.c
ir_rx_irq.c
ir_rx_irq.h
)Check example.c for a basic starting point.
// 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);
...
}
