PWM-LED Configuration

Hello Team,

I am working with Thingy91x and I was checking whether is pwm led or pwm gpio can be configured for nRF5340 of Thingy 91x. If possible will you please let me know the steps I need to follow to configure pwm channel in Thingy 91x nrf5340 and get pwm output.

Kindly please let me know the limitations for this steps.

Thanks and regards

Vinay

  • Yes, PWM can be configured for the nRF5340 on the Thingy:91 X

    Step 1 :- PWM in prj.conf

    CONFIG_PWM=y
    CONFIG_PWM_LOG_LEVEL_DBG=y
    CONFIG_LED=y
    CONFIG_LED_PWM=y

    Step 2 :- Pin Control & PWM in Devicetree Overlay

    &pinctrl {
        pwm0_default_alt: pwm0_default_alt {
            group1 {
                psels = <NRF_PSEL(PWM_OUT0, 0, 30)>;
            };
        };
    
        pwm0_sleep_alt: pwm0_sleep_alt {
            group1 {
                psels = <NRF_PSEL(PWM_OUT0, 0, 30)>;
                low-power-enable;
            };
        };
    };
    &pwm0 {
        status = "okay";
        pinctrl-0 = <&pwm0_default_alt>;
        pinctrl-1 = <&pwm0_sleep_alt>;
        pinctrl-names = "default", "sleep";
    };
    
    / {
        pwmleds {
            compatible = "pwm-leds";
            led_pwm_0 {
                pwms = <&pwm0 0 PWM_MSEC(20) PWM_POLARITY_NORMAL>;
                label = "PWM LED 0";
            };
        };
    
        aliases {
            pwm-led0 = &led_pwm_0;
        };
    };

    Step 3 :- application code

    #include <zephyr/device.h>
    #include <zephyr/drivers/pwm.h>
    
    #define PWM_PERIOD_NS   20000000
    #define PWM_PULSE_WIDTH 1400000
    
    static const struct pwm_dt_spec pwm_led0 =
        PWM_DT_SPEC_GET(DT_ALIAS(pwm_led0));
    
    int main(void) {
        if (!pwm_is_ready_dt(&pwm_led0)) {
            return 0;
        }
        pwm_set_dt(&pwm_led0, PWM_PERIOD_NS, PWM_PULSE_WIDTH);
        return 0;
    }


    Step 4 :- thingy91x_nrf9151_ns.overlay (external power fix)

    &exp_board_enable {
    /delete-property/ output-low;
    output-high;
    };

    Build with west build -b thingy91x/nrf5340/cpuapp and flash. Let me know if you hit any issues!







  • Hello Nishant,

    Thank you for your reply. I really appreciate it.

    But I am facing issue while building this configuration.

    I am adding the logs and the project zip file which I have configured as per your guidance.

    Thanks and regards,

  •  in thingy91x_nrf9151_ns.overlay contains something like:

    &exp_board_enable {
    ...
    };

    remove this reference and try again

  • Hi Nishant,

    I am able to build it without any errors. Thanks for that.

    But when I probe Trace0 pin in current measurement and debug board connector. But I cant see any pwm output. Will you please let me know what else I can probe to get pwm channel output. Or am I missing something here?

    Thanks and regards,

    Vinay

  • Hi Nishant,

    Is it possible to configure LED as an PWM output channel for Thingy 91x/nrf5340 SoC?

    Thanks and regards,

    Vinay

  • Hi vinay 

    Sorry for late response

    yes it is possible to configure LED as an PWM output channel as LED2 is connected  to the nRF5340 SoC and the pins are ;

    P0.14 Red
    P0.26 Green
    P0.15 Blue

    here is the code base for this https://github.com/NordicDeveloperAcademy/ncs-inter/tree/main/l4/l4_e1_sol , i hope this will help
