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,...

Re: Support for 32-bit Windows?
The trouble with operating in 32 bits is you need a gcc-none-eabi compiler built for 32 bits. Fortunately, they are there https://developer.arm.com/downloads/-/gnu-rm and not least, you need the full suite of glibs and libs that gcc runs on, along with any libs that the rest of the tools depends on....

Re: How to access low level registers or How to set TIM1 to 128Mhz
dannyf I think the op kind of mentions that stm32g071 timers can do 128 Mhz. it is something quite interesting to explore, that is practically VHF, FM radio frequencies if you noted. in a sense if that is possible, even for that matter use it as an oscillator, mix it with FM radio waves from an ant...

Re: Properly handling timer overflow ?
assuming that you are using stm32f103. I think in stm32f103 the timers are 16 bits. but that it has a prescaler which is 16 bits I've not reviewed the codes really. But that keep rm0008 handy as it tells you what is ultimately available in the hardware. https://www.st.com/resource/en/reference_manua...

Re: How to access low level registers or How to set TIM1 to 128Mhz
128 Mhz is probably above the cpu clock frequency e.g. for stm32f103c8 72 Mhz, you can probably at best get like 72 Mhz or more commonly half or less like 36 Mhz. for the 'official' STM core, the wiki is here https://github.com/stm32duino/Arduino_Core_STM32/wiki hardware timer API is documented here...
