that device has uart

have you tried that?
uart just take different pins and is normally accessible at Serial1, Serial2 etc.

Re: STM32F407VGT6 programming issues
one thing to try is to press and hold reset when you flash the sketch over st-link, this is called 'connect under reset'. If the tool chain is properly installed, sometimes that will override the write protection. flash a simple sketch such as to blink the led, so that you know if after all it is wo...

Re: How to port Arduino firmware into STM32 Cube IDE
For beginners, it is much easier to simply follow the getting started guide https://github.com/stm32duino/Arduino_Core_STM32/wiki/Getting-Started and to use a supported board on the STM core page. https://github.com/stm32duino/Arduino_Core_STM32 it is also suggested to get a chip that has more sram ...

Re: stm32h723 mini core board camera module
if you bought it from e.g. weact
https://github.com/WeActStudio/MiniSTM32H7xx
you may need to contact them
there could be more than a few vendors, hence, it may not after all be weact, you may like to check from where you bought the board from

Re: [STM32F103C8T6] How can I use '128 Kbytes of Flash memory'?
officially u'd need to get a stm32f103c{b,B}t6, that one has 128 k per specs, c8 is 64k per specs. So if you think you literally have 128k memory, you can try a variant for 128k e.g. maple mini. The details are actually in the ld script, check in there in the variant. Alternatively, get something li...

Re: STM32 hangs when >100khz signal applied to input
try something like a stm32 f4xx (e.g. stm32f401 / f411 ) board, those has the FPU, but that it is for floats only.
other things to try are to move the computation codes into loop() and only use the ISR callback to simply count cycles, e.g. increment a global variable.

Re: How to use PC14/PC15 as GPIO on STM32F407VGT6
PC14 OSC32_IN PC15 OSC32_OUT is normally used for a 32 khz crystal for the RTC. it is probably not a good idea to use them as gpio ports. e.g. there is likely a 'not gate' connecting PC14 to PC15 with some extra stuff. that 'not gate' is literally used as an amplifier, given sufficient conditions e,...
