DIY Arduino Clock ESP32 and RGB Matrix

This video shows my one day RGB Matrix clock, Check out PCBway.com
I will show you how to do build one on your own
Used I2S RGB Matrix Shield: www.tindie.com/products/brian...
Source code:
github.com/atc1441/ESP32-I2S-...
Example LED Matrix: de.aliexpress.com/item/326522...
Needed library's for Arduino:
ESP32: dl.espressif.com/dl/package_e...
Adafruit GFX library
Adafruit BusIO library
The code includes a modified version of this Library:
github.com/mrfaptastic/ESP32-...

Awesome

[@MrDenisJoshua]

Great video... I will make it but only with 2 matrix ...cause with 4 matrix I think is too big.
Thanks a lot

Great project. As for your Wi-Fi issue, it could be a signal strength connectivity problem. Try using an external whip antenna if your module has a connection for one.

[@atc1441]

Thanks.
Yeah the antenna is pretty hidden behind the pcb

Hi, great project, I ordered directly a led matrix. is there a way to get you're pcb???

[@sub-arts128]

hi, how may modules of p10 32x16 or pixel-resolution can the esp32 drive with 32 bit color depht and good framerate? thx

[@javiles2331]

Awesome 👏🏼 can you put pictures or any other pixel art?

[@atc1441]

Yes, anything is possible with this setup

[@MrDenisJoshua]

Hi there... I have a screen of 256x128
So this card can be good for me please ?
Thanks

[@atc1441]

If you use low colordepth it will work

Hello Aaron. Thanks for sharing this! I am trying to compile your code for my ESP32 but am getting this error "'GPIO_PIN_MUX_REG' undeclared (first use in this function)
". It is in the i2s_matrix.c tab. Any suggestions? :-)

[@atc1441]

Hey. Would need to look into it as well.
Maybe try to downgrade to a version from the time the video was made. Something could habe changed, just to see if it works then

[@wclumiere5665]

@David Kempton I was having the same compiling errors, I had to use ver. 2.0.5 of ESP32-HUB75-MatrixPanel-DMA library and esp32 core ver. 1.0.6

Jlpcb charged me 7 dollars with shipping. Pcbway wanted over 100usd

[@Really2950]

Esp8266 !!

[@atc1441]

No the ESP32 can only be used here, as it drives the Display via the I2S interface

[@jstro-hobbytech]

Pcbway cost way too much.
