Arduino for STM32

Hello,
Does anyone had problem with receiving CAN message to STM32F1.
I have multiple devices on bus, some of them are ESP32(receiving and sending is working), STM32F1(only sending packet is working).
CDC is disabled. Core that I am using has added changes to support HardwareCAN library, just to say ...

This is compile error for FastLed example with official core in attachment :

Does anyone have solution for compiling FastLed (any version) library with official STM32 core? STM32F1 is used

It just flush tons of undeclared classes and function errors, like it doesn't recognize FastLED library at all

Yes, disabling peripherals done the same.
Regarding LED library (adafruit_dotstar) it compiles with STM32 and Roger's core successfully, but it runs output only in Roger's, on official core compiler output is not flat-lined. I could use FastLed as well instead for my project, but it doesn't compile ...

Thanks for this clue.
I found the way to disable usb clock, so i dont have to care about disabling CDC and serial in settings in matter to have working CAN anymore...

void InhibitUSB ( void ){
*((uint32_t*)0x40005c40) = 3 ; // USB_CNTR
*((uint32_t*)0x40005c44) = 0 ; // USB_ISTR

__HAL_RCC_USB ...

I am already using PB8/PB9 mapping.
Problem is somewhere else. Even when i enable CDC and generic Serial, COM port is not shown in Device Manager with this CAN low level code flashed.
Something is blocking USB CDC HW serial. I have solution with software serial, but this is only temporary fix.
Just ...

Hello,
I'm using this same lowlevel example, and works OK.
But having trouble with Serial. When i enable "generic USART Serial support" and "CDC generic Serial supersede", CAN stops working.
When i disable these hw serial supports, CAN works fine. Serial printing is important for developing code ...
