Multiprocessor mode with address mark detection only receives data which has '0' as MSB. After waking up (RWU=0) when the correct address is received subsequent bytes should be received normally, and not interpreted as another address?

I have configured the UART for multiprocessor communication over RS485. I can receive and transmit data correctly, but if the data contains a '1' as MSB it is interpreted as an address. Now it is clear from the documentation that this is the correct ...

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...
