A new display supported by the ESP32-S3

[cicciocb]

This is the PCB I did recently

The PCB is plugged directly on the connector and is supplied at 5V with a little connector.
The board contains a SDCARD where you can store all the images / gifs

Can you upload sample code for 2x2 panel?

This is a very sample demo :

Code: [Local Link Removed for Guests]

Dmamatrix.delete
DmaMatrix.init 5,7,6, 8,10,9, 11,12,13,14,15,  16,17,18
DmaMatrix.setup 4, 2 '4 panels on 2 rows (2x2)
dmamatrix.fill 0
dmaMatrix.show 0, 0

for r = 1 to 100000
 x=rnd(128):y=rnd(128):dmamatrix.circle x,y,10,rnd(65535),1:cnt=cnt+1
 dmaMatrix.show 0, 0
next r

Hello, is it urgently necessary to an ESP32 S3?
Do some ESP32 Lolin have it, do they work?

Many greetings

No, it works only with the ESP32-S3.

Hello,
I'm currently struggling with the Oscillate instruction. I wanted to define a line for a scrolling text with DMAMATRIX.LIMITS. But it only moves the whole image. Is there an example program?
Best regards

Oscillate always move the complete image so you cannot scroll a single line.
You can print a text at different positions using DMAMATRIX.TEXT.POS x, y , clearing before with DMAMATRIX.FILL color, [x, y, width, height] so that, changing the y coordinate in a loop can show a scrolling text.

Thanks for the quick reply. I misunderstood the limits command.

Hello,
The display is now running quite well on the ESP32 S3 WROOM-1. If the data is displayed, the WiFi connection is lost after a short time. Since I use the module to display data received via UDP, data is lost. What am I doing wrong?

I notice similar when I have a shield plugged into my S3 UNO, which would normally have a good wifo connection... so it is perhaps due to your display module reducing the wifi signal to the S3.
Perhaps you can test that simply by temporarily turning the display module so that the S3 has better line of sight towards the router.

In my case I could use an external aerial, but perhaps you might give ESPnow a try, cos it has about double the range, requires no router connection, and has a handshake capability which could be used to resend any unreceived info.

How your module is powered? Maybe it requires a stronger power supply for that purpose. Otherwise it could be a question of EMI of the pins as the module drives the pins with high strength. You could try to use the command pin.strenght on the pins defined for the display.
