SDK • SOLVED: Can the Status LED and the RGB LED be used together with pico_status_led?

Code:

//============================================================// BlinkyLED_RGB.//// Can we use the RGB and normal status LED at the same time?// It appears so, but there may be problems after flashing or// powering on the board as sometimes the RGB LED doesn't come// back on.//// Tested on Vcc-gnd yd-rp2040 boards with 16Mb on board. //// Requires SDK 2.2.0 or higher.//// Norman Dunbar.// February 4 2026.//============================================================// NOTE.//// You will see some "return 0" statements in the code, used// when the Status LED isn't supported or won't initialise. In// embedded systems, returning from main() is considered a // no-no! However, with the Pico, returning from main() will// call exit() which then calls _exit(), which spins. So, we// can safely return from main().//============================================================#include <stdio.h>#include "pico/stdlib.h"#include "pico/status_led.h"int main() {    const uint32_t colours[] = {0x00000030,     // Blue                                0x00300000};    // Red        stdio_init_all();    //--------------------------------------------------------    // Do we have status LED access?    //--------------------------------------------------------    if (!status_led_supported()) {        printf("Status LED is not supported.\n");        return 0;    }        //--------------------------------------------------------    // Initialise the LED, wherever it is.

Power on - sometimes both LEDs ok, usually not RGB.    // 6. Short RST press, usually bring RGB LED on again.    // 7. Bonus! Id RGB is on and ok, short RST press hangs it    //    showing just one colour.
