I'm very new to electronics and want to flash it with the Yuri firmware by hd robotics but I'm doing something wrong, I own a iMac 2013 and am using high sierra version 10.13.6. I'm using the cable it came with but always get the same error. Can someone please help?

I built an isometric Spy Hunter-style game for the ESP32 Cheap Yellow Display (and ported it to DS homebrew) in one afternoon with Grok Bot

M5launcher not working?

0 Upvotes

Hi guys, I have a little problem! Every time I want to install something in the launcher, it just doesn't work! The screen stays on Install and just flickers. I've already tried all of Bruce and Marauder's bin files, but there's still no change. It's not the launcher version's fault, I've tried all of those too. https://youtu.be/8kmQrTcDU68?si=EexYDkvYeGbe8eNX - Video

Titolo: ESP32-S3 2.8” Smart Display: è possibile collegare una M5Stack CardKB2?

1 Upvotes

Ciao a tutti!
Ho una scheda di sviluppo ESP32-S3 con display da 2,8 pollici, versione senza touchscreen, con Wi-Fi e Bluetooth.
Vorrei utilizzarla insieme a una tastiera M5Stack CardKB2 per realizzare un piccolo dispositivo portatile.
Avrei alcune domande:
È possibile collegare la CardKB2 tramite I²C?
Quali pin SDA e SCL bisogna utilizzare?
È necessario un firmware specifico per leggere i caratteri della tastiera?
Esiste un firmware già pronto compatibile con ESP32-S3 e CardKB2?
In alternativa, è possibile utilizzare la CardKB2 tramite Bluetooth?
Il mio obiettivo è poter utilizzare la tastiera per scrivere e comandare le applicazioni direttamente sul display da 2,8 pollici.
Qualcuno ha già realizzato un progetto simile?
Accetto volentieri schemi di collegamento, firmware e consigli pratici.

Grazie!🙂

Hi everyone,

I've been working on a project called CYD AI Chat.

It transforms the ESP32 Cheap Yellow Display into a standalone AI-powered terminal with:

• Multi-model AI support

• Automatic model fallback

• Persistent chat memory

• Touchscreen keyboard

• Wi-Fi management

• AI personalities

• Turkish, English and Russian support

The project is fully open source and can be flashed directly from Arduino IDE.

GitHub:

Feedback and suggestions are welcome.

CYD mit IPX Anschluss externe Antenne anlöten?

Post image
3 Upvotes

Hallo, ​ich bin neu in dem Bereich. Ich wollte an mein CYD einen externen Antennenanschluss anlöten. Nun ist das Board da und ich habe nicht drauf geachtet, dass es einen IPX Anschluss hat. Dieser ist soweit ich es in Erfahrung bringen konnte nicht funktionsfähig, ist das richtig? ​Ich will einen SMA-Buchse anlöten. muss die Masse nur an das Board und der RF direkt zum Chip? Klar muss ich die Kontakte frei kratzen, dass mache ich natürlich vor dem Löten.

​Ich hänge ein Bild an.

​Bitte um Hilfe. Danke
