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...

STM32H723xx won't program at 3.3 volts but will program at 3.2 volts

I am using a STM32H723ZGT6 on a small project. The project fails to program when I am using 3.3 volts. It programs just fine at 3.2 volts. Always gives me a fail in final launch sequence. However, it always programs when I apply a small amount of...
