About ADC conversion time

Hi,In STM32L073, the ADC conversion time is stated as 0.875us with 12-bit resolution.Even in the actual test, it has been confirmed by the continuous operation of 1ch of ADC.However, I set the ADC results to be transferred by DMA, the ADC conversion ...

For seat reservation at New STM32H72x/3x MCUs for running deeply embedded applications Online workshop Thursday, March 11th, 2021: I already have the board

In (STM32F103RB) Advanced-control timers (TIM1), I wonder why PWM signal (TIM1-CH3N) is not generated.

I want to generate a PWM signal through the Timer.(STM32F104RB) In CubeMX, "channel 3" of timer1 (TIM1) is set to "PWM Generation CH3N", and "channel4" of timer1 is set to "PWM Generation CH4".The parameter settings are the same as shown below.(Presc...

STM32H747: UART7 with DMA.

Hello!I have strange issue with DMA mode for UART7. I have callback for data transfer complete, but if i sending new data - i have broken data. If i added timeout - all data sending Ok.does anyone have any thoughts?

Erase Flash in STM32H730ZB by flash word.

Hi,I want to implement custom bootloader in STM32H730ZB, It has 128KB of Flash and only one sector. If I want to load image using bootloader then, I need to erase particular portion of flash. Is there any support to erase flash by flash word? If I er...

STM32F446 UART: Reading received 9th bit (i.e. DR[8]) in USART_DR when PCE=0 and M=1 in USART_CR1

I want to interface to an existing RS-485 bus where the 9th bit (normally reserved for parity) is set to 1 for the first two packets of each frame (as an addressing mechanism) and then cleared to 0 for the subsequent "data" bytes.If I set PCE=0 in r...

STM32F091 how to detect suspected CPU stall through Flash access?

I'm having trouble with my IAP erase and write of Flash in my custom bootloader. I need to overlap comms activity with Flash erase so comms doesn't time out, but despite attempts to force the bootloader code, ISRs and vector table into SRAM, my suspi...
