Stm32 array declaration4/13/2023 Well, unless you change frame length, which is really bad idea anyway. UART does not receive "lines" or "data", it receives bytes. If you were able to receive any data using DMA then you pretty much done with the hardest part. I have been using HAL_UART_Receive_DMA and I have been able to store simple lines of data Then you can use the that pointers they way you would use 2D arrays. ![]() Printf("1st element of the 2nd new array : %d\r\n", new_arr) Printf("5th element of the 1st new array : %d\r\n", new_arr) Printf("2nd element of the 1st new array : %d\r\n", new_arr) Example for 20 elements with pointers to element 0 and element 10: int recieved_arr = now define a pointer to first element, another one to 10th element and so on. ![]() you have a 10x10 array (a matrix!) and you get one array of 100 elements. To answer that specific question, it's completely up to you to format and use it. you can use this to import your computer files without UART/DMA hassle. In addition to printf and scanf, it allows you to use file IO standard libraries. Screen and keyboard of the host instead of having a screen and For example, you can use this mechanism to enableįunctions in the C library, such as printf() and scanf(), to use the To communicate and use the Input/Output facilities on a host computerĮxamples of these facilities include keyboard input, screen output,Īnd disk I/O. ![]() Semihosting is a mechanism that enables code running on an ARM target
