Resolved! DFSDM Output resolution

When I use DFSDM, I configure FOSR= 256 ISOR=1 and the output is outside the range in the reference guide +-16777216

In the case of STM32U575ZIQ, Can I use an external DMA (and not the internal I-DMA) to interface the SDMMC card?

Basically, when I use the IDMA of STM32U5, there is a significant delay happening while communicating with the card. And if I do the same by using STM32F4(which uses general DMA), then there is not such a huge delay. After checking other parameters (...

Resolved! ADC output suddenly becomes constant

Hello,I'm using the ADC on a STM32G431 to read 5 voltages at 20kHz. Everything works well, but suddenly the 5 channels "get stuck" or freeze, i.e. the value they measure becomes constant even though the voltages on the input pins still fluctuate. Som...

Resolved! customized PCB with STM32F7 series uController can not be seen by any STM programs(ie. STM32Cube programmer, STMCube IDE, St utility ...)

After changing some properties, those are: -"BOR_LEV" set up 1 (BOR Level 2 VBOR2 brownout threshold level 2) -"RDP" set up CC (level 2 chip protection) from "Option Bytes" segmentation in STM Cube Programmer(It was unintentional case and before th...

Resolved! Can you please send the stm32F401RET6 data Sheet.

I want STM32F401RET6 Data sheet with register details. I want to write the code on register based.

Hi, I am using STM32G0B1KBU6. I tried read ADC with DMA but DMA block my runtime. Why does DMA do that?

I2C is not sending a repeated start

Hello. I encountered a problem. I have an STM32F103C8T6 controller and I am trying to implement I2C communication using interrupts. The problem is that when I need to send a repeated start, it doesn't happen. ITBUFEN interrupts are disabled, I only u...

Hello, I would like to know how to configure I2C with MCU STM32L5. Thank you for your helps

I have a CODEC SGTL5000, I need to communicate by I2C but I have an error I don't know if it comes from hardware or software? Thank you for your help

Resolved! On our design, the STMF405 supply voltage could be as low as 1.77 V at -40 degrees (worst case component tolerances). Is there a possibility that the processor will fail to boot or could there be any other performance issues?

Resolved! wrong UART interrupt is getting fired

I am using UART to transmit and receive data. for transmitting I am using polling method function HAL_UART_Transmit(&hart1, buf, 8,1000) and for receiving i am using HAL_UART_Receive_IT(&hart, Rx_buf,8); receiving is working fine but after transmitti...
