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...
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...
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...
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...
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...
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 ...
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...
Hello, I use HRIM on STM32F334 for a buckboost. Before entry in control loop I need to force TA1 output high during 20mS to pre-load capacitor.To force TA1 output, I use : output_config.SetSource = HRTIM_SET1R_SST; output_conf...
Dear experts,I'm trying to receive continuously from a USART with interrupts.For some reason I don't want to use DMA (the Tilen Majerle's DMA example on github works well, though)So I'm enabling RX FIFO and Receive timeout (RTO) for receiving less th...
Hello,After trying almost everything I found online, I’m posting here for help.I’m working with an STM32H747I-DISCO board, aiming to exchange data via USB CDC with Windows. I’ve configured the .ioc for USB CDC device (FS or HS) on the Cortex M7 core....
