NRST pin characteristics of STM32F2xxx

STM32F20x datasheet talkes about TNRST_OUT, but Figure 40 shows NRST pin as input. Which is right?In view of point NRST can be behaved as OD output, then it will expand the external reset pulse is expanded by 20us?e.g.In other words, external periphe...

STM32F103 chips from different origins cannot program

We purchased the STM32F103 MCU chip in the China, and it can be seen from the silk screen that there are two origins, one is Malaysia and the other is Taiwan. For the same HEX program, MCUs made in Malaysia can be programmed and erased normally throu...

Hi everyone, when I try to debug my STM32L452RET6P microcontroller, it's showing an 'Error in initializing ST-Link device. Reason: No Target Found on Target'. How can I solve this problem? Note: I have already tried full erase chip but it didn't work.

Trouble with configuring CTC for STM32F303ZE Nucleo board

Hi,I did the basic set up for configuring the usb micro A device connector added on the nucleo board (not the ST-Link connector). Clock is set for usb (HSE, 48MHz through PLL) and the USB_VIRTUAL is set on CTC. I generated the code with Cube IDE and ...

Hello! I have a nucleo-f042 board and notices something funny. When I use a usb hub or my docking station I get the "No ST-Link detected." Strangely I am still able to re-flash the firmware and see it's serial number in the Cube IDE.

Powering a daughterboard from a STM32F4 Discovery Board for prototype

I need 16 DAC outputs for my project. I was planning on using Texas Instrument's DAC8168IAPW over I2C and making a daughter board to connect to the Disco board. I also plan on adding an IC to drive LEDs. Do I power the daughterboard using the Disc...
