Hi, I am currently trying to set the data time of the can_fd function to 8Mbps for can_fd communication.However, when I set the data time to be 8Mbps, the communication does not proceed normally.When I set the data time to 1,2,4,5 Mbps, it worked fin...

Hello I'm currently trying to change the classic CAN into FDCAN, but when i try to change the clock source of FDCAN (which is PLL1Q) from 50Mhz to 80Mhz to use FDCAN, the clock configuration keeps giving the message "wrong parameter values" when i tr...

Hello I am trying to do spi_dma communication using the HAL_SPI_TransmitReceive_DMA function.When I use HAL_SPI_TransmitReceive_DMA in a situation where I use the same dma stream, same amount of data to send and receive, but different addresses to se...

Hello,I'm trying to do SPI communication with an ADE1201 chip through an STM32H753VIT6 chip.The maximum allowed frequency of the ADE1201 is 10MHZ, so I set the SPI to communicate with the MCU at 6.25MHZ.(The clock for SPI communication is 25MHZ, and ...

Ohh... so the transceiver delay compensation is needed when using the can fd data time which is over 5Mbps.after when i added the transceiver delay compensation, a waveform with a size about 192ns is added before the err waveform occured. I think by ...

In the datasheet it says"Without transceiver delay compensation, the bitrate in the data phase of a CAN FD frame is limited by the transceivers loop delay"you are saying that this could be the cause of my error?

The transceiver is TCAN341x, and it says it supports 8Mbps in its datasheet"Support of classical CAN and optimized CAN FD performance at 2, 5, and 8 Mbps" No, I didn't tried the Loopback mode, can it be used for this solution?

My understanding is that the higher the Hz, the higher the power consumption,so why would using different modes at the same Hz increase the power consumption?

In the Table 121, it says the VOS3 mode has a maximum 200mhz.but before this you said to change the system clock at 400MHz, which is the maximum of VOS1 mode.So.... does this mean that i have to change into VOS1 mode to use 400mhz?Instead of setting ...

I can't set the can_fd Data time in 8Mbps, what could be the problem? (STM32H753VIT6)

Why can't I modify the clock value associated with the fdcan in stm32h753VIT6?

Is it possible to split HAL_SPI_TransmitReceive_DMA function in this situation?

I have a problem of using SPI in STM32H753VIT6 CHIP
