My STM32F205 processor cannot be found

Hi!I designed my own development board with the STM32F205 microcontroller. But I can not find my processor via stlink and uart in any wayHow can I fix this problem?

Can we do XiP with STM32L476RE? Will the performance be good with running code from external memory?

Hello,I am using STM32L476RE and want to do XiP. So will it support XiP?Will the performance be good with running code from external memory?TIA

ADC-DMA Test can't work on STM32H757 i-EVAL Board

I want to test ADC-DMA function on STM32H757 i-EVAL Board. But the result is DMA transfer error. I just copy the example code of STM32Cube --- STM32H743I-EVAL\Examples\ADC\ADC_DMA_Transfer to my STM32H757 project.When execute the code, it occurs onl...

STM32G4xx FDCAN Delay Compensation

A little something I have noticed today. I have been developing an application which is using the G431 and uses FD-CAN. My code was working in External Loopback mode such that a CAN message of my choosing was being correctly received by an external d...

Hello Everyone. I am working on STM32F103VG controller and trying to code for I2C based EEPROM IC (AT24CM02). I am facing some issues with writing and reading EEPROM.

I want to save 2 strings of 127 bytes of data in 1 page. 1 page is 256 bytes each. Whern I try to read and write 127 bytes of 1st string, it works successfully. But when I try to append 127bytes of 2nd string,it does not read and write data properly....

Im trying to connect a flight controller/esc board to an application im using on my cellphone but when i plug in the FC and try to connect it will not read the port connection?

UART not receiving anything

Hi I have a code bellow:static void MX_UART8_Init(void) {   /* USER CODE BEGIN UART8_Init 0 */ GPIO_InitTypeDef GPIO_InitStruct = {0};   /* USER CODE BEGIN UART8_MspInit 0 */   /* USER CODE END UART8_MspInit 0 */ /* Peripheral clock enabl...

DAC output differs between Channel 1 & 2 on Nucleo-F446RE

Hi :) I found something quite strange, it seems that:1) On DAC Channel 1 - the output buffer does not work (a 10kOhm load brings the voltage down), but it's output is inverted (as expected)2) On DAC Channel 2 - the output buffer does work (maintains ...
