MCUXpresso SDK : led component

gph — Fri, 16 Sep 2022 15:16:09 GMT

Hi,

I'm trying to use the "led component" of SDK on LPC54606.

On/Off are working well.

But LED_Flash & LED_Dimmer only made On state.

Here my code :

Console_Print("Test LED_\r\n"); uint32_t s_ledMonochromeHandleBuffer[((LED_HANDLE_SIZE + sizeof(uint32_t) - 1) / sizeof(uint32_t))]; led_handle_t s_ledMonochromeHandle = (led_handle_t)&s_ledMonochromeHandleBuffer[0]; led_config_t ledMonochromeConfig; ledMonochromeConfig.type = kLED_TypeMonochrome; ledMonochromeConfig.ledMonochrome.monochromePin.dimmingEnable = 1; ledMonochromeConfig.ledMonochrome.monochromePin.dimming.sourceClock = 48000000; ledMonochromeConfig.ledMonochrome.monochromePin.dimming.instance = 0; ledMonochromeConfig.ledMonochrome.monochromePin.dimming.channel = 1; ledMonochromeConfig.ledMonochrome.monochromePin.dimming.pinStateDefault = 1; ledMonochromeConfig.ledMonochrome.monochromePin.gpio.port =0; ledMonochromeConfig.ledMonochrome.monochromePin.gpio.pin =1; ledMonochromeConfig.ledMonochrome.monochromePin.gpio.level =0; ledMonochromeConfig.ledMonochrome.monochromePin.gpio.direction =kHAL_GpioDirectionOut; LED_Init(s_ledMonochromeHandle, &ledMonochromeConfig); Console_Print("LED OFF\r\n"); LED_TurnOnOff(s_ledMonochromeHandle, 0); SW3_WaitKey(); Console_Print("LED Flash\r\n"); led_flash_config_t ledFlash; ledFlash.times = LED_FLASH_CYCLE_FOREVER; ledFlash.period = 500; ledFlash.duty = 50; ledFlash.flashType = kLED_FlashOneColor; LED_Flash(s_ledMonochromeHandle, &ledFlash); SW3_WaitKey(); Console_Print("LED Dimming\r\n"); LED_Dimming(s_ledMonochromeHandle, 500, 0); SW3_WaitKey();

Probably i miss timer/pwm initialization, but i don't find what to do.

Thanks for your help, Philippe.

Hello,

How about refer to the LED_control_bm demo routine under SDK for lpc54628 ?
