Hi, I´m trying to implement ESD protection to a custom board, I found recommendations for this part number (USBLC6-2SC6), which clamping voltage is as follows Look at VCL Clamping Voltage there are 12V and 17 V Then the USB pins of my MCU accept a ...
Split from this thread. i've had the same issue. Set the internal pull-up on Rx pin and pull-down on Tx pin.
Hi everyone! I designed the board shown in the attached picture. It’s built around an STM32H745 microcontroller, along with crystal oscillators, a DAC, an EEPROM, and an NE555 that generates a reset signal when a button is pressed long enough. Afte...
Hello,I am designing a board with a STM32F446 connected to an IS42S16160H SDRAM through the FMC interface.Could you please provide ST’s official recommendations regarding the use of series resistors on FMC lines?Typical values (22–33 Ω)?Any ST guidel...

The goal of my project is to turn on an LED on the recieving side through CAN. Both my reciever and transmitter have the transciever circuit. Both are Nucleo boards, TX: F303RE, RX: F446RE. The data i am sending through is 16-bit, but as long as my r...
I am trying to read ID and to write and read the data from the flash W25Q16JV with SPI2 of stm32L452CE connection, I am not even getting the ID from flash but SPI tx rx is getting HAL_OK. This wiring is working other code and providing unique ID from...
I am using an STM32F7 Nucleo Board with SPI/I2S to get audio data from this MEMS microphone.https://www.adafruit.com/product/6049?gad_campaignid=21079227318gad_campaignid=21079227318 I am having issues with none of the signals triggering: WS, CLK, or...

Hi there, Ive gone around in circles for hours on this. I'm just trying to read a frequency, around 150Hz typ. using the 32 bit timers, for now just TIM2, 4 channel but behaviour same on all channels. Using 16MHz clock the timer overflow happens arou...
