Hello,My original project was created for STM32F030c8t6 and I want to get the list of compatible MCU, so that I can migrate my project to STM32f103C8T6. I opened the cubeMX table from CubeIDE. While I clicked the list of compatible MCU, the programs...

I wanted to use the ioc and all the code from a project into another project. So, I copied the project and pasted in a workspace, then renamed the project, but ioc is not changed. So while opening, I get error messageInvalid Input: Must be project's ...

Hello,Target is power from another source. STlink from USB of laptopI was wondering if the power ON/OFF of STLINK and the target sequencing will damage either the devices? I had one STLINK v2 seems to be damaged while debugging and later it is not ab...

Hello,I am trying to make STM32F020c8t6 enter boot loader by connecting the Boot0 pin to HIGH via a 10k as given in some forms and pressing the reset. I connected the MCU UART1 to Laptop running Cube Programmer and use the UART option. The MCU uart1 ...

I observe a strange behavior for cubeIDE. I was working in a specific work space recently for few days. I was not in logged in state to "myST". I wanted to refer to other work space and switched the work space. It says "no project exists". Then I tri...

I suggest you begun with simple example to echo the characters. Then you buildup on that. This method help both we and you to be in sync during discussion.

May be you should analyze the buffer to check for some marker such as \r\n or STX character, subtract from the total bytes to receive, and call dma for the balance bytes. Then again start for the full bytes in the next cycle.

this part was missing in your code and an empty while loop as per the example quoted by you.. how do you test if you have received the characters, do you use debugger?void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ HAL_UART_Transmit(&huar...

please make this HAL_UART_Receive_DMA(&huart2, data, 255);as HAL_UART_Receive_DMA(&huart2, data, 4); in your while(1){if(flag == 1){flag = 0;HAL_UART_Transmit(&huart2, data, 4, 1000);HAL_UART_Receive_DMA(&huart1, data, 4);} Connect to
