basic search, so not too difficult
But this doesn't provide of any infos where those bytes are located in the chip, for example in STM32F103C8.

the STMF1 has two special bytes, called "User data storage option bytes".
I don't see any such references in datasheets, where did you saw that other than Flash Loader Demonstrator ?
Perhaps it is simple bytes written somewhere at the end of uploaded firmware ...

Re: very small STM32F405 board

STM32F405 or F407 are already supported since more than 2 years.
Maybe some feature missing, but just tell us which ones ... ;)

Re: Need advice: Metal detector with stm32f103

Obviously there is some problem with this library when used with ST-Link. In the same thread ahull suggests better not to use JXXX pins. I used PB4 and after reading the ahull's suggestions I changed it with PA11, but it still does not work. Yes, that's why I told you about pinouts, PB4 is JNRST. I...

Re: Need advice: Metal detector with stm32f103

LiquidCrystal doesn't need bootloader.
But maybe you changed the GPIO pinout by mistake ?
Of course, you can't use SWCLK/SWDIO as plain GPIOs...

Re: Which define defines the stm32 core for libraries?

There are severals ones, but the most common is __STM32F1__ or __STM32F4__, depending of MCU type.
Simply look at the compile command with verbosity turned-on ...
