STM32G071 HSI RC (internal RC oscillator) accuracy // RC oscillator use for UART
Where is the accuracy if the HSI RC (internal oscillator) specified? I cannot find any data. There seems to be some presentation slides but this is no a valid specification. I need the worst case accuracy over the complete temperature range. I have r...
dual core data share
HI I'm working on STM32H745. I'm tiring to understand share data with 2 cores. Can you please post a program ?
TIM1_BKIN Behavior When Fault is Detected
Please I want to Know how TIM1_BKIN for example in STM32F103C8T6, behavior when it detects fault and when the Fault disappears? What is the approximate Time it may take to turn off the TIM1 PWMs Channels ant when the fault disappears, does it delay ...

STM32L4 only does debug session only every other time.
I have a problem when debugging STM32L4 form CubeIDE with STLINKV2, the debugger only starts every other time. First start of debug session is ok, program halts at "main()". When debug session is closed and started again, the download is successful, ...
How does watermark for FDCAN work? - STM32H7
Thats a question that has bothered me for a while. When receiving FDCAN messages, I can specify a watermark on how many bytes the interrupt triggers.How exactly does it work?If I have a message of 8 bytes and I set the watermark to 1 byte, does the i...
Stm32 operate on 400MHZ clock frequency. Then what is SPI frequency
Hello , I am using NUCLEO-H7 board it operates on 400MHZ clock frequency the APB clock is 100MHZ.But on which frequency spi operate on 400MHZ or 100mHz. In stmcubmx clock configurationSPI 1,2,3 clock mux option selected is PER_CK 64 MHZ. And baudat...
