…O (PA13) and SWCLK (PA14) connect those to your ST-Link and progam as per most of the STM32F103 board. There is a GD32 version of the bootloader, but I don’t know how up to date it is. If the firmware is locked on your device, you may not be able to back it up…

- How to change the clock speed of STM32L476RG nucleo board?
Pito
I didn’t understand! STM32F103 chips (Cortex M3, 72MHz one) like BluePill have got 2 wait states while reading from flash memory. It means they do not usually perform 1 instruction per clock. STM32F4xx chips (Cortex M4) like L476 have got “ART accelerator” – a…

…ect, which is open source (but requires Keil/IAR to build) and has been ported to the STM32F103. Off the top of my head, the DAPLink firmware weighs in at about 50KiB and the bootloader adds another 32KiB. If you want to use a smaller chip like the F042 (I ass…

… to be crystal related, or poor soldering by the board producer, rather than a faulty STM32F103 That should be, I didn’t think that STM would sell bad MCU. The Blue Bill board I got was cheap Chinese clones, poor quality was acceptable. DS3231 is a good soluti…

…for anything better, you would indeed need an op-amp. If the best we can get from the STM32f103 is 10bits, then you are reduced to about 6 bit accuracy (31 steps).. and so forth. There is an interesting article on oversampling on the STM32 series here -> ht…
