Flowcode Support Board

Hi to All

I use a Atom S3 with a display. It's working nice with an extern AD converter and shows the values on display.
But I can not send the values to the App-developper
I found a help in the internet, there is an intern UART-USB Brige.
How can I use it?

Select UART0.
Enter the default pins of the ESP32-S3:
TX → GPIO43
RX → GPIO44
Even if you do not wire the pins, Flowcode will know which UART it refers to, and the output will be correctly transmitted to the PC via the USB-CDC port

Hi Stefan.
Have you looked at all the PC developer projects here.
There are projects that use USB for communicating between hardware and PC developer using USB

Hi Martin

Yes, right now again. If the board has a UART to USB bridge (for example, CH340C), it works very well.
I have already done many projects with it, and that work very well with the Appdevelopper.


Now the problem:
Many new supermini boards with ESP32-C3, ESP32-C6, ESP32-S3 no longer have an additional IC (UART-USB bridge) on the board.
However, Flowcode does not yet support a direct USB connection for the ESP32.

There is another option for the small ESP-S3 chip.
The ESP32 S3, which has a UART-USB bridge integrated into the chip, as I understand it.
It can be used with uart0 and set TX/RX on GPIO 43 and GPIO 44.

I just don't know exactly how that works with Flowcode.

Hi Martin

I am not yet able to establish a connection between the ESP32-S3 and the PC.
However, I have more information on this.

I'll have a look- it should be possible using the OTG USB interface...

Hi Stefan,

Can you try this - run idf.py menuconfig
component config - esp system settings - channel for console output -> Set this to USBSerial/JTAG Controller

NB - target must be set as an esp32s3 (idf.py set-target esp32s3)

Check if usual debug is then sent to USB (using PuTTY for exanple)

Then try using a UART on Pins 19 and 20

I don't have an s3 to test
