I've been working on understanding and refactoring this code, but there is one thing, I don't get:
What is the OFFSET for?
And where does the value come from?

Hello ;
leds initilization work seamlessly when i have the xiao esp32s3 connected to the PC on USB.
But it hangs when i plug off the USB cable an try to make it work powered on battery.

Apparently, it's this line that hangs inside _initled function :

ESP_ERROR_CHECK(esp_lcd_new_i80_bus(&bus_config, &i80_bus));

Any clue ?
Regards,
Xavier

Hi , thanks for your awesome work on various area (i am using also esp32Artnet and Fastled) ;
Your DMA solution to free the CPU from handling LED display is just smart and elegant.

It works flawlessly with the Xiao ESP32S3 of course;
But i am considering using the Xiao ESP32C3 (only one core and no PSRAM, only "normal" RAM) , as only one core should be enough ;
I have two issues trying to compile on the c3 :

• lacking resource "hal/hal_lcd.h"
• no PSRAM on the c3, only RAM.

Do you have any hint i could work on to address that issue ? (or maybe it is just not possible)

Regards,
Xavier

Hi hpwit,

Thanks for the library, it works great with RGB leds. But now I would like to use it with RGBW leds, is there a way to achieve this? Please let me know!

Kind regards,

Thomas

Hello

How to use matrix functionality with yours driver?

Hello,
I have configuration:
#define NUMSTRIPS 8
#define NUM_LEDS_PER_STRIP 60

#define EXAMPLE_PIN_NUM_DATA0 26 // B0
#define EXAMPLE_PIN_NUM_DATA1 47 // B1
#define EXAMPLE_PIN_NUM_DATA2 48 // B2
#define EXAMPLE_PIN_NUM_DATA3 38 // B3
#define EXAMPLE_PIN_NUM_DATA4 39 // B4
#define EXAMPLE_PIN_NUM_DATA5 40 // G0
#define EXAMPLE_PIN_NUM_DATA6 41 // G1
#define EXAMPLE_PIN_NUM_DATA7 42 // G2

doesn't work for me

Can I ask for help?

Arduino IDE 2.2.1
Board ESP32-S3 mini PS ram

Thank you

I'm testing your library for this parallel output for ESP32-S3 and I must really thank you. For my project of 11000 leds WS2815 reduced my lag from 1400 to 40 ms for show. I have question or request about lengh. Is it possible to make modification for parallel output with different lenght of strip?
