Describe the bug I have ESPixelStick firmware installed on an Esp32 cam board, version below. LANDZO ESP32 CAM Module Development Board ESP32 with Camera Module The on board LED come on startup after re-booting. What options do I have for turning off the on board LED?

MartinMueller2003 commented 2 years ago

There is a setting in the ESP-Cam GPIO Defs file. You define the pin being used for your LED on your platform and the startup code will turn it off.

brmeadows2841 commented 2 years ago

I believe it is already defined in GPIO Def file. But light is still on at start up, not as bright as the flash but still on.

define LED_GPIO gpio_num_t::GPIO_NUM_4

MartinMueller2003 commented 2 years ago

Is that the correct GPIO for your device?

brmeadows2841 commented 2 years ago

Yes GPIO4 control the flash, but apparently if I use the SD card the flash is also turned on.

The ESP32-CAM has a very bright built-in LED that can work as a flash when taking photos. That LED is internally connected to GPIO 4.

That GPIO is also connected to the microSD card slot, so you may have troubles when trying to use both at the same time – the flashlight will light up when using the microSD card.

Note: one of our readers shared that if you initialize the microSD card as follows, you won’t have this problem because the microSD card won’t use that data line.*

SD_MMC.begin("/sdcard", true)

we found that this works and that the LED will not make that flash effect. However, the LED remains on with low brightness – we’re not sure if we are missing something.

I assume you built the image for the "ESP32_CAM" target? If so then the SD card will not work anyway since the SPI pins are different between your board and the ESP32-CAM board.

Our SD Lib only uses two data lines and Data2 in your chart is unused. If you built for the ESP32-CAM board type then GPIO 4 should be held high after boot. It is possible that your card needs the line held low. I can add a selector for defining the proper state for LED off. This can be fixed by updating the GPIO definitions in the cam file or creating a new board type.
