Hello everybody. I need to share external and software RESET between two different electronic boards. I designed a circuit based on transistors and optocouplers. The soft reset ground the NRST pin, this way I would like to trigger an optocoupler, but...
I am trying to blink two led's one is connected to pin 5 (green led) and second is red led and for blinking i set it to pin 6 but the issue is that i am not able to blink red led(LD1) and the green led(LD4) is properly working . Can anyone help me re...
The file en.MB1381-H750XB-B02_Schematic.pdf states that H750XB only supports LDO mode, then SMPS should be OFF, as in the below figure: The schematic file is different as in the below figure: My question is the schematic below would cause any problem...
Hello,according the datasheet for "STM32F302x6 STM32F302x8" -> "6.3.4 Embedded reference voltage" there is the definition of Vrefint as 1.23 V. But how exactly is it generated / derivated?I also checked the advanced Arm®-based 32-bit MCUs - Reference...

Hi all,I am using the STM32L452RET6 On my board and i have 2 quiestion regarding it:1) VDD12 Net - how to set my hardware when i am not using external DC/DC? floating? GND? just a cap? if so what size?2) when entering boot mode and going over the i/o...
TL;DR What's the magic sauce for connecting to an STM32F7 with SWD on ST-Link?Hello everyone. I am perplexed because I have been unable to program my custom board based on the STM32F765VGT6. (Hardware Eagle files + pdfs, Logic data captures, and so...
Specifically, when T_VCC is not supplied, what state are the pins in for the STLINK-V3SET? We are using the SWDIO, SWCLK, and JTAG pins on the STDC14 connector CN1.
