Ambiguous LQFP100 Pin 1 Markings?

I have just wasted three solid days of very intense bench work trying to understand why my STLINK programmer will not communicate with my newly-created 32F419 target board. As a result I am now an unintended expert on SWD programming.The reason my t...

What To Do When SWD Port is Non-Responsive to STLINK?

I have a newly-birthed target board based on 32F413. My programmer is an STLINK V2 with STMCubeProgrammer code.What are good strategies when the SWD port is non-responsive to the STLINK programmer?Must the micro's unused JDTO and JTDI pins be termin...

SWD or JTAG: How Does Recently-Birthed Target Know Which?

I'm posting here because STM32CUBEProgrammer announces it cannot find my Rev.2 target board. More puzzling is that it finds my Rev. 1 target just fine.I made these design changes between Rev. 1 and Rev.2 target boards:--I boosted the voltage on my V...

I am getting a problem with STM32F103RBT6. The problem in pin of microcontroller. I am use the pin for a button . but microcontroller after some month or days the pin short to GND(pin to GND resistance is 68 ohm with power OFF and ON time).

Looking for STM32F103X STM32F103RCT6 Microcontroller Development Board specific documentation (board schematic, installing the bootloader (if even necessary), programming instructions for the board).

Scoured the internet for past few days and found lots of general STM32 information but nothing for this specific development board . Any help would be appreciated.

Wi-Fi support and/or best practice for new board-design?

Hi!I basically have two questions:Regrettably, there are no STM32 MCU:s that comes with built in Wi-Fi support and I am curious to fund out the reason for this? Perhaps any new products in the pipe? The need for new IoT applications must by huge thes...
