I'm sttarting with STM32. I've bought Nucleo STM32H745ZI-Q and I'm trying to bling a LED (or any other GPIO). I've downloaded CubeIDE, CubeMX is included in it. I'm tring to Toggle GPIO pin, i've tried few tutorials on yt with no luck. ST-Link is up ...
I have a question about a signal (Interrupt signal) in the STM reference manual RM0433. On Page 697 , table 125 the Trigger input 14 is named "Lptim5_ait". I cant find any reference for this signal.
I'm trying to set up a BDMA Stream with Lptim5 as trigger source. Which interrupt on the Lptim5 can i use? "Lptim5_ait" is not listed as an interrupt in the Lptim section of the manual ( page 1881, table 350).Happy new year and thanks in advance!
