First Design Perimeter Sender

Do you have an OLED at your mower?
I've used the same librarys like in the mower code. There are different options for different oleds.

No, i used a raspi with TFT on the Mower.

 

[SefanH]

I've integrated ArduinoOTA now. It works!

Wich display do you use for the sender? I've bought a 4 pin ssd1306 from the friendly chinese, but i use the sh1106 driver and it works without the black bar at the right side.

 

[Sascha]

I used a IZOKE 0,96 Zoll Display.
I've had it lying around here for a few months.
I have tested all the settings that can be selected, and it stays off. I have no problem with Bernard's code, the display works with it.

 

[Bernard]

Certainly you are using different kind of display

What's the difference between Adafruit SSD1306 and SH1106?

Hey all! I've scoured some pretty sketchy sites in search of this, and haven't found anything concrete. I have a need to use Adafruit's SSD1306 library for my OLED displays. The problem? I'm using these cheap ones which only support SH1106...

Maybe the code i use into the mower is able to manage the 2 kind of over U8g2 ? But you need to find the ESP32 version.

I think the I2C address is different to my screen. I'm not sure, but i think my screen is addressed at 0x3A?!

 

[Bernard]

0X78 is write on the PCB according shunt location , so need the same address on the firmware

Cool .
In fact you don't need the small voltage regulator, it is already include in the L298N driver ( your small Ground wire)

Den habe ich leider nicht in KiCad aber dafür den L7805CV, sollte die gleiche Funktion haben.
Dann baue ich den da noch ein und dann die Beschriftung der Pins noch und dann kann ich hoffentlich bestellen.
Ein paar Leute warten ja schon auf ihre Platinen.

Why did you want to add a 5V regulator ,The L298N driver generate the 5V.

Here picture of the basic PCB wiring ESP32 power by L298N driver.

and start up Video of the screen :

J'ai vu que le driver du moteur avait une sortie de 5V, mais j'ai opté pour un régulateur de 1A-3,3V parce que je voulais jouer la carte de la sécurité.
