Will there be a STM32H7 version of the STM32F765 part.

STM32F7 maximum speed

Recently, I began to deal with the STM32F7 stone, as the STM32F4 lacked speed. By the result, I realized that if you simply run the same program (calculating digital filters) on F4 and F7 at the maximum core frequency, then the performance does not i...

I erase flash memory L051 with uart,fail ,return back 1F,but 44 BB is ok,return 79,what's wrong?

command orders:7F return 7992 6D return 797F return 7944 BB return 79FF FF 00 or FF FE 01 OR FF FD 02 return 1F

STM32F407 RTC

I use the RTC of STM32F407 with LSE (32.768 kHz).A battery is connected to VBAT for backup.In the reference manual, the Backup operating voltage is at least 1.65V, but the RTC is actually backed up to about 0.3V.I do not know the reason. Could you te...

How to use external interrupt as toggle. for start and stop some process. For example start and stop pwm stream I think the challenge is having wakeup pin and external interrupt pin on same pin. Any help would be greatly appreciated.

I am using stm32f429 , i am getting error while i am doing RX operation, I am able to perform TX operation. USART1 is not even updating the register value during debug operation. if anybody has faced same situation please share answer.

Multi slave SPI for STM32F427ZIT6

Hi,I am using STM32F427ZIT6 for one of the design. I am new to designing. I am connecting 8 ADC's to this device using SPI. I am using SPI4 (Pin 1,4,5). I want to know whether chip select (8 nos) can connect to any IO's?? Because NSS (slave select) i...
