Hello ,in STM32 H742 data sheet I find CAN pind with or without the suffix FD_MODE, but there is no explanation on it. What does that mean? CAN peripheral has only one output for Rx and Tx each. Can't I use those without FD_MODE when using CANFD but ...
I wanted to use RTC Circuit for Supercap.I have designed circuit (Check Attached snapshot).but i dont get back up time? can anyone explain do we need to do any provision in controller.It seems that capacitor is discharging very fast
ia m using STM32h743II MCU and i am trying to transfer SPI data from spi4 block defined as SPI MASTER to spi5 block defined as SPI SALVE without success.I am using the HAL_SPI_Transmit from the SPI MASTER block (spi4 block) and HAL_SPI_Receive from t...
I am seeing a very strange glitch from the PWM output of TIM8:CH1 on an STM32F730.The timer is running on 216MHz internal clock, with an ARR reload of 617, giving a ~350kHz PWM output.There is also a no-output Compare on it's channel 2, used to trigg...
Hi. I found a bug in RTC shadow registers inconsistency of seconds and subseconds.Subseconds are counted from PREDIV_S down to 0. Then the seconds are incremented and subseconds start again from PREDIV_S.Sometimes subseconds contain PREDIV_S value an...
