What is the equation to calculate the FDCAN clock on STM32H743xx?
I know its clock is provided from the APB1, but I can't figure out how to calculate and what are the relations between fdcan_ker_ck and fdcan_pclk

Resolved! Problem in the I2C1 peripherical?
Hi to all!I have an Nucleo-F767ZI board and I noticed a problem, in the I2C1 periperical.I have redirect the I2C1 pins on PB8 and PB9 for comodity and left PA6 and PA7 free and the I2C1 work well.After a couple of days, i have used the PA6 pin as out...
More information about the comparators integrated in the stm32l052
Hi,I would like to have more informations about the both integrated comparators in the stm32l052 because we only have the propagation delay informations in the stm32l052 datasheet.I would like to know the rise/fall time and propagation delay vs. over...
STM32F302K8 I2C weirdness
I have noticed some very strange behavior with the I2C controller. It appears that when it has a slave address match, it sets the ADDR ISR flag and raises an interrupt ( if enabled ). If I have a breakpoint in the interrupt handler, the ISR BUSY fl...
Resolved! RM0444 Rev.3 still downloaded as Rev2

STM32H7 SPI communication issue: RxFIFO management
I've been struggling for quite a while now on my SPI setup.The setup is as follows:- SPI Slave is a Nucleo STM32H743 in simplex mode, clocks at maximum (sysclk 400MHz, hclck 200Mhz, APB clock 100MHz)- SPI master is another identical Nucleo in simplex...
Reading I2C bits with STM32F4Discovery
Hello. I have the following scheme for reading the output of humidity sensor that communicates via I2C:How would I execute this sequence with STM32CubeMX IDE and HAL libraries? The output of the sensor is as follows: All I have now is this code: uint...
Resolved! The SDIO_CK clock is unexpectedly stopping during an eMMC erase command. Why?
I'm trying to erase the entire eMMC chip using an STM32F405.I send CMD35+CMD36+CMD38 and get the expected R1 response from all 3 commands. After CMD38, the D0 line goes low to indicate the chip is busy erasing. About 1000 SDIO clocks after CMD38, the...
The purpose of DSP and MAC integrated to MCU, like 16 bits MCU ST10F276 and it's special applications.
ST10F276 ( 144 pins, 512 Byte Flash, 320K Byte Xflash) has integrated with DSP and MAC, what the purpose of it? any special application for such configuration? which STM 32 bits MCU have same construction? thanks.
