pwm hardware individual loading mode nrf52

[akshaey]

Please can anyone help me on how to use(program) PWM hardware with individual loading mode? My goal is to control 12 LEDs individually with different duty cycles and playbacks using pwm hardware which has 12 outputs to make a kind of led chaser.

Thanks in advance

please check the program i have attached-

drive.google.com/open

i have copied code from pwm_driver into pwm_library and have added relative .c files like app_timer.c or nrf_drv_pwm.c It gives the following error-

._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_timer_init (referred from main.o). ._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol bsp_buttons_enable (referred from main.o). ._build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol bsp_init (referred from main.o)..

etc

what am i missing to add? Please let me know. thanks

i have modified and put the sdk_config file, now there are no errors, the hardware pwm is working on demo 5, but the software pwm is not. this is the final code--

Sorry for late response, I was on vacation.

Why do you use this code in the middle of main() ?

   for (;;)
    {
        // Wait for an event.
        __WFE();

        // Clear the event register.
        __SEV();
        __WFE();
        NRF_LOG_FLUSH();
    }

This is infinite loop and you won't be able to execute code under this loop

i have got a working code for managing 12 hardware pwm + 8 software pwm together to make a led chaser for 16 leds. Check the following link
