OPTA Potenta H7 - STM32H7 - HRTIM - Master Timer Update Interrupt & Repetition Interrupt not Firing
Hi,I'm developping on an Arduino OPTA (STM32H74x) Portenta H7 and I want to use the high-resolution timer for driving some interrupts-based actions, actually using only the master hr-timer (no output). >> Problem: The code doesn't want to fire any in...
Resolved! Startup sequence for STM32H7 (dual core)
Hello, is there any documentation regarding the startup on both cores as I see there are several possibilitiess to gate the other core or to let them run directly in parallel. Nevertheless, CubeMx generates a common startup file which is shared I ass...
Resolved! Wrong reference temperature given in ds H747
Hi,in ds for STM32H747xI/G , DS12930 Rev 2 , for Temp.sensor CAL2 : 130° (Parameter) is written here: BUT max. temp for chip is 125° :So i assume, this is misspelled , because in all other : (H743, H750, H7A3 ..) 110° + 30° are given.NOT 130° .
