STM32L4A6 config WKUP pin to low level trigger fail
Hi all,I wan to use WKUP pin exit standby mode for low level trigger.I set WKUP pin with low level polarity in HAL_PWR_EnableWakeUpPin() function and pull-up WKUP pin.but the MCU alway wake-up when enter standby mode.When set WKUP pin with high l...
Resolved! How to set values for the timing Register in STM32F303RE in I2C
I try to write the driver for I2C and I open the reference I face a problem in setting values for SCLDEL SDADEL SCLH SCLL and I don't know how to set theses values. I kept searching and I saw there is an Excel sheet you can enter the Pclk and I2C spe...
Resolved! Using STM32F723 I2C with multiple slaves at different voltages
Dear ST Microelectronics Team,I want to connect a STM32F723IE with I2C as master, which is powered with 3.0V, to a bus with one slave with 3.0V and to another slave with 3.8V. From the datasheet I can see that the GPIOs are 5V compliant, but can the ...
External crystal not oscillating
Hello,I have custom board. I am working on STM32H7 controller. We use the external crystal of 25Mhz. But when we use that external oscillator using the HSE ,it doesn't provide the clock to controller. Why these happening. Can you please help me

I am unable to find any working examples for this specific board with SMBUS/PMBUS.I am also having lot's of issues converting a SMBUS project from a different board.It would be great if anyone could assist me in either getting FW specific to the boar...
RENODE emulator vs. STM32L072 - how to "complete" MCU model?
Has anyone here worked with Renode? An emulator remotely similar to QEMU, but more geared towards MCUs, esp. w.r.t. emulating peripherals.https://antmicro.com/platforms/renode/Renode does not seem to have a forum, only the github issues for their pro...
Any easy way to find out after WFI() if device did sleep?
Is there an easy way to find out after the WFI() instruction if the device did really sleep? Using stop modes, the device will have switched clock to HSI/MSI. Setting the clock to the state before sleep is some effort and could be omitted, if sleep...
