Hello Everyone, I'm trying to write a float value into my STM32H743VIT6 flash memory, bit it jumps straight to the HardFaultHandler and I cannot understand why... Here's the two functions: HAL_StatusTypeDef Store_AltitudeMax(float altitude) { ...

Hello everyone! I'm close to validating all my schematics for a PCB project, and I wanted to be sure at 100% that a section is correct.I'm talink about the USB-C section, that connects directly to the STM32H7 microcontroller. It will be used to acces...

Hello TDK,Finally I found the solution.Actually, the Both functions seems good.the 3 defines that i created during the issue were the following : #define ALTITUDE_MAX_ADDRESS 0x081E0000U #define FLASH_BANK FLASH_BANK_1 #define VOLTAGE_...

I think I made a huge mistake! As they are N-Channel MOSFETS, they're supposed to switch the "low side" of a load. So the previous schematics are totally wrong..Here's the correction :
