Hi Steve, Hi Martin

Steve: Can you try if the ESP32C3 is compling on your computer?

I found this information:

CPU architecture / ISA extensions (VERY important)
ChipEffective -march
ESP32‑C3 rv32imc
ESP32‑C 6rv32imac_zicsr_zifencei
ESP32‑C6 requires additional RISC‑V extensions
zicsr
zifencei

Hi Martin, Hi Jorgen, Hi Grout Stefan - output seems to imply it can't find the compiler?? Yes, exactly. But the compiler is there, and the DLLs are there too. Somehow it just doesn't work. I'm using the latest toolchain installer from FC11. (Flowcode_Compiler_ESP_5.3a.msi) With an older version, th...

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.

Hi Martin

Your program is working fine

Maybe You need ESP-IDF 5.3.1

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

Code: Select all

python "C:\Users\Kfs-Forschung\Desktop\esp-idf-2\tools\idf.py" add-dependency esp_tinyusb

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

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)...
