What is the best way to protect pin from external 'high' voltage (10-30-60 or higher V). Is it even possible without external buffer, resistor + clamping diodes etc.?Input with high Z, open drain, other methd for "disconnecting" pin will do the job...
STM32L412KBUx on NUCLEO-L412KB, STM32CubeIDE, Version: 1.8.0.I'm trying to power my NUCLEO-L412KB from an external +5 V power source. I have removed SB9 (connected NRST signal of ST-LINK to the NRST pin of theSTM32). SB1 (USB power through CN1) is OF...
Which Pin should I set and reset to make a power cycle happen in STM3G4 or any popular STM32F3xxx.. ??I have 2 mcu's and with one of it I want to do a power cycle..I mean to remove the power and connect it again. What should I do here?
Hi,I tried to set the read protection to level 1 (the one where we should be able to wipe out everything) .But after that i can't get no connection anymore with STM32IDE , ST-link or any tool. Connection is completely broke.Before changing this level...
The board can be populated with a Quad SPI PSRAM, sharing OCTOSPI1. Do I need to remove the OctoSPI before using the Quad SPI or is it enough to disconned CS?
How I understand from this schematics: PC8 and PD2 have pull-up resistors connected to them while the rest of them don't, this means that the rest should get Pull-up resistor in the settings of the GPIO and this will enable the pull-up resistor from ...
Hi,we have a PHY with several bootstraps. Some of them are shared with the RMII from a STM32H753 (see image below, controller is on the left).A FreeRTOS+TCP network stack is used, which, when rebooted, first does some low level inits with HAL_ETH_Ini...
Hello,We working on custom board. We using this controller STM32745IIkx. In JTAG we connect the USART1 port, but there is pin mapping issue, so I am unable to use USART1.So instead of UASART1 can I use USART2.I am sharing its schematic THE VCP_TX and...
