Resolved! STM32F429 and STM32F407, the corresponding DMA routines of these two chips.
�?�以直接将STM32F429的DMA例程直接下载到STM32F407中使用�?？我这边直接下了进去，�?试了一下，�?�现串�?�没数�?�。应该是�?对STM32F429的例程修改�?STM32F407版本的例程？如果是�?修改的�?，具体应该修改哪些地方呢？�?次接触，特�?�请教感谢�?

Where is STM32H735G-DK full .hex file as supplied from the factory?
There's a file STM32Cube_Demo-STM32H735G-DK-V1.0.0 on the website, but it's not the one referenced in the accompanying .bat file (which has a name ending in "FULL") and seems to just (sometimes) load up the selection screen but mostly gives me a blan...
About half-duplex communication (Rx frame size is 3)-2
Hello,Is it possible to perform half-duplex communication like the attached document? (I understand that the timing to switch to Rx is tricky.)The Rx frame size is 3 instead of 1.After changing to Rx, can I receive 3 bytes continuously as shown in th...
What happens when a STM32H747 encounters a skipped clock pulse on its HSE clock input every few million cycles?
I wonder if a regularly or sporadically missed clock pulse on the HSE clock input has any (negative) effect on the operation of the H7 processor or any clock output from a HRTIMER.My guess is that the internal PLL might lengthen the next pulse a litt...
Is it possible to reset the CM4 from the CM7 on the STM32H747?
Or at least make software reset work on only one core?Thanks
Connecting PWM output to input on the same board
Good day everyone,At the moment I'm trying to connect a PWM output pin to a PWM input pin on the same board. I'm using a dual core MCU, so both of them are on a different core.I set TIM4 to the M7 and TIM15 to the M4. I enabled the interrupt for TIM1...
[STM32H7] Why is there no spread spectrum functionality?
Hi,as there is apparently no more spread spectrum functionality in the STM32H7 to reduce EMI, is there some counterpart? I heard that the PLL fractional divider might be used for that purpose, but the amount of processor overhead to change the three ...
Is the STM32H7A3RIT6 ever going to exist?
Announced over a year ago - I developed a product based on it and still no silicon
Resolved! STM32H743-EVAL2, why battery-backed RAM doesn't hold data?
I start from any simple Cube example, such as UART_Printf,enable access to the backup RAM and write some data.After reset by the reset button or NVIC_System_Reset data in the backup RAM is retained.But after powering off the data is lost.Do I miss so...
