I am leaning to program the H743ZI and have a simple application where the user leds blink at a certain rate given by a delay produced by a for loop.When the code is uploaded, I get the desired rate. If I disconnect and connect the board again, the p...

Got it!When using TSIZE, application must wait loading all data into TX data register before testing for TXC, while I was testing for TXC every time I loaded some data (in fact waiting for TXC to be set). This works if TSIZE is zero at the start of ...

Hi,Your question is relevant to the one I have. I am writing an SPI polling transmission application for learning purposes. If I don't load TSIZE, all works fine and I can measure the MOSI and SCK signals with a logic analyzer. The application checks...

Angus,You have to look at the specific entries of the "Port x alternate functions" tables in the datasheet (that Clive mentioned) in order to know the relation among SPI functions, the GPIO ports and pins that implement them, and the corresponding AF...

Following your comment, I wrote a code to read the system clock source (from the RCC_CFGR register) and blink the user LED with the result.Right after the code upload, PLL1 is selected as system clock. Turning the board OFF and ON again, the slower H...
