esp32-s3-usb-otg devkit, Use green and yellow LEDs not working (AEGHB-139)

[HeadHodge]

Hi,

I'm trying to use the onboard yellow and green LED lights.

Im using:

// Turn On Green LED
pinMode(GPIO_NUM_15, OUTPUT);
digitalWrite(GPIO_NUM_15, HIGH);

// Turn On Yellow LED
pinMode(GPIO_NUM_16, OUTPUT);
digitalWrite(GPIO_NUM_16, HIGH);

Neither LED, turns on. I'm using the GPIO_NUM stated in the esp32-s3-usb-otg devkit docs.

Please help Thanks

@HeadHodge Hi, are you developing with Arduino?

Hi, are you developing with Arduino?

Yes (btw... the menu button works fine)

`void setup() { Serial.begin(115200); delay(4000);

SysTools::addLog("%s", "lcdDisplayTest::Setup");

// initialize the LED pin as an output:
pinMode(GPIO_NUM_16, OUTPUT);
digitalWrite(GPIO_NUM_16, HIGH);

//gpio_set_direction(GPIO_NUM_10, GPIO_MODE_OUTPUT);
//gpio_set_level(GPIO_NUM_10, 1);

pinMode(14, INPUT_PULLUP);

}

void loop() { // read the state of the pushbutton value: SysTools::addLog("buttonState: %u", digitalRead(14));

// check if the pushbutton is pressed. If it is, the buttonState is HIGH: if (buttonState == HIGH) { SysTools::addLog("%s", "button high"); // turn LED on: //digitalWrite(ledPin, HIGH); } else { //SysTools::addLog("%s", "button low"); // turn LED off: //digitalWrite(ledPin, LOW); }

//delay(2000); }`

//delay(2000); }`

Ok, I will test it as soon as possible.

@HeadHodge Well, I use your code and all leads turn on. Do you have a voltage gauge to measure the voltage? Maybe they are broken...

[HeadHodge]

Maybe they are broken...

Thanks for your time.

I forgot i had another new unused board. When I plug uart/usb cable into my laptop both leds start flashing and the espressif logo displays on the lcd!! The other board never did that. 😏 So seems like bad board.

Before I toss the board, do you know how i can program it to factory default?

Thanks

@fairytail655 > Well, I use your code and all leads turn on. I did the same on the new board and it also works!!

But to do that, I had to flash my program over the factory default.

I would like to flash the factory demo bin back to the board. I think I found the bin file, but not sure what address to flash it to and not sure if there are co-binaries needed to be flashed. Any insight would be very appreciated.

factory_bin:

[fairytail655]

@HeadHodge Sure, you can flash the bin to address 0x00.

[HeadHodge]

Sure, you can flash the bin to address 0x00.

It works... THANKS!!!

Everything is good now! Thanks Again

Yeah, you're welcome. If there're no more problems, please close this issue. Thanks.
