Resolved! STM32H563 Debug mode stopped working
Hello,While debugging STM32H5 SPI2 (slave and master) in receive mode, the debug suddenly stopped and somehow I can't work in debug again.

Resolved! EOCIE set, EOSIE not set, but EOS triggers and EOC doesn't
Hello!I am having weird behaviour on my STM32G071 MCU.I set up the ADC to measure in sequence and I want to get an interrupt when the sequence has finished. The ADC is set up with DMA and I am starting conversions manuallty within my loop that runs o...
maximum USART baud rate on STM32U0
Hi, I would like to determine the maximum baud rate for a USART peripheral in asynchronous mode. In the datasheet (Figure 1) the maximum baud rate is given as 8 MBit/s. But even if I set the clock for the USART peripheral (in this case USART1) to the...
Readout protection errorr
I am using the Readout Protection Level 1 security method for the STM32G431 chip. However, after flashing the code, it doesn't work, and when I use the STM32Programmer software to check, I encounter an FF error like this. Can anyone help me with this...
Issue with RWW Configuration Using OSPI1 and OSPI2 on STM32U5A9J-DK
Hi, We are using the STM32U5A9J-DK board and are trying to achieve Read-While-Write (RWW) functionality. The flash chip we are using supports RWW. Earlier, as per [this post](post link), we learned that to achieve RWW, we need two OSPI instances, nam...
Configure STM32H750 ADC123 to simultaneously capture same channel in independent mode?
As the title suggests, the chip manual states that in dual ADC mode, ADC cannot be configured to simultaneously capture the same channel, but there is no explanation for independent mode. Is it feasible in independent mode? If not, what are the reaso...
I2C initialization waveform issues
I use the arm chip stm32f401 to communicate with eeprom, and observe the waveforms of the clock and data lines. The rising and falling edges of the initial write and read waveforms are not square waves, but are slow and have some glitches. Later, whe...
Can the array DAC DMA for signals be controlled?
I generated a sinusoidal signal through the DAC using DMA. I understand that DMA performs looping since I use circular mode. In short, I want to control the numbers generated by the DMA. So, when the signal changes to DC (the array contains only 2048...
Resolved! NRST trigger duration STM32H743XIH
We are having trouble understanding the NRST pin characteristics.The STM32H742xI/G STM32H743xI/G datasheet gives these parameters:I have three questions:1. What does 'input filtered' and 'input not filtered' pulse mean?2. Is it by design true that a ...
Problem with software interrupt on STM32H563
Hello the comminity.I try to use a software interrupt with no secure and no privilege.when I set a bit in EXTI_SWIER1 And re-read the register, the value stay to 0.When the interrupt was fired, It's impossible to distinguish the software interrupt f...
