Re: STM32SD adjust file timestamps?
apparently STM32SD https://github.com/stm32duino/STM32SD depends on FatFs https://github.com/stm32duino/FatFs which has a getfattime() callback https://github.com/stm32duino/FatFs/blob/bf405bad29c66accd9df5570084ad80a8c78cd11/src/ff.h#L295 https://github.com/stm32duino/FatFs/blob/bf405bad29c66accd9d...

Re: I2C communication does not work.
I2C requires a 'different skillset' vs playing with uart, uart is point to point, it is only 2 devices a sender and the other a receiver and vice versa. but of course it is up to one to make things complicated by adding RS485, RS422 etc, but that is off-topic. Then that for i2c, many devices share t...

Re: I2C communication does not work.
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...
