Hi Ben The ESP32 and ESP32S3 work, but the ESP32C3 and ESP32C6 don't. What should I do? -- Found Git: C:/FC_ESP/esp-tools/tools/idf-git/2.44.0/bin/git.exe (found version "2.44.0.windows.1") -- git rev-parse returned 'fatal: not a git repository (or any of the parent directories): .git' fat...

Hi Martin

I expanded your example to include an array for sending data, and it works.
I can also receive the binary data array very easily using the Flowcode APP Developer.

Demo:

Hi Martin

Your program is working fine

Maybe You need ESP-IDF 5.3.1

and in the menuconfig batch file
this line ....

Hi Martin

Your suggestion works perfectly!

I had to make a few adjustments. Sending is done using the function in the additional code. How can I send an array from my program? I'm not sure exactly where I need to add FCV_.

Hi Ben Various components use UART for communication, such as GPS/GNSS components. The ESP32S3 has the major advantage of having three UARTs. You can choose the pins for two of them, while one is assigned to a fixed pin. However, Flowcode currently only supports 2 Would it be possible to add a third...

Hi Martin

Thank you Martin I'll give that a try.

I've had a bit of success with `print_F` so far.
I still have no idea how to send an array

Very short program: C-Code: On computer (regardless of the baud rate)

Hi Martin I've now updated to 5.3.1 and added the USB Tiny dependency. I also have some C code there can I use it in Flowcode? include are ok: #include "tinyusb.h" #include "tusb_cdc_acm.h" #include "esp_log.h" 2026-03-30_11-36-59.PNG C-Code for USB: void app_main(void)...

Hi Steve V14 works very well. One more question: Templates are sorted by displayed name (and not filename) Is there more information about the templates (exsamples) ? Can I just copy one of my programs to the “exsamples” folder? I'm interested in the ESP32S3 Templates and would also like to understa...

Hi Martin One a question: There is still one entry missing : CONFIG_USB_DEVICE_ENABLED=y CONFIG_TINYUSB_ENABLED=y CONFIG_TINYUSB_DEVICE_ENABLED=y CONFIG_TINYUSB_CDC_ENABLED=y in the file: sdkconfig.defaults.esp32s3 But in FC11 there are so many sdkconfig.defaults.esp32s3. Which one is the right one?

Hi Martin
