Arduino for STM32

At this point, i don't know why are you getting those errors.
My first guess is that core is not properly installed or selected.
Try to compile blink sketch from File->>examples->basics->blink

I tried TNTSC libray with MisakiFontOut.ino and stm32_DemoNTSC.ino from TTVout library and it compiled without errors on my PC.
Arduino IDE 1.8.19 and Generic STM32F103C board...
Are you using Arduino 2.0 IDE ?

Place TNTSC library in library folder, so full path will be: C:\Users\15183\Documents\Arduino\libraries\TNTSC
NOT in core library folder ( C:\Users\15183\Documents\Arduino\hardware\Arduino_STM32\STM32F1\libraries\TNTSC )

I don't think F411 have that feature.
Quick search for "RNG" in CMSIS:
19 out of 24 do have it, but F411 is not one of them.

Either use noise from analog input, as ag123 suggested, or implement some LFSR in timer interrupt.

CMSIS definition from https://github.com/stm32duino/Arduino_Core_STM32/blob/main/system/Drivers/CMSIS/Device/ST/STM32F4xx/Include/stm32f407xx.h I think this should be enough: // Write to register RNG -> CR = 0; RNG -> CR = (RNG -> CR ) | RNG_CR_RNGEN; // enable bit RNG -> CR |= RNG_CR_RNGEN; // enab...

Almoust as bluepill. Your board just don't have Timer4 compared to bluepill. But RM0008 apply to your board too.
I am not familiar wirh Roger's core DMA syntax, but i'm pritty sure there must some command to set lenght of DMA transfers ( for CNDTR register).

I was experiment with DMA to ODR, but with official core, and directly with registers. From what i understand, on bluepill, you can only use DMA1 to send either PortA or PortB, not both. In your example, dma_setup_transfer(DMA1, DMA_CH0, &GPIOA->regs->ODR, DMA_SIZE_16BITS, &dataA[step], DMA_...

See here.

Thank you for that link. I have W806 board that was waiting more than a year in the box
Blinking leds works !

I once found same thing in SdFat library, called "FreeStack.h" From that, simple sketch should work (at least at STM32F1/4): // from SDfat library extern "C" char* sbrk(int incr); // free RAM (actually, free stack inline uint32_t FreeBytes() { char top = 't'; return &top - re...

just 2 cents, if you are changing all the bits in one go, you may as well use ODR. for BSRR, to do the same, it may be 2 transactions, first reset all bits, then set the bits again separately. the alternate would be to do things like GPIOA->BSRR = value | (~ value << 16); I agree. In this case (R2R...
