Hello, Sometimes I have my stm32F7 going in hardfault_handler, so for my customers I have to display on a screen the last address where the software crashed, then I can analyse which problem occure the crash. So I want to get the value "pc" (program ...
While using memory mapped mode for APS6408L using STM32u585 on B-U585I-IOT02A, how is the row boundary crossing handled?* If I want to write across multiple Rows in memory mapped mode, do I need to handle this manually or is it automatically handled ...
I've been using an STM32G474xx in a project for a few years now and have a function that jumps to the bootloader. It seems in a recent rev of the chip the bootloader has changed. I'm finding that I can no longer jump to the bootloader similar to how ...
In my project I use FDCAN1 and FDCAN2 for communication.At startup of the system CAN1 ist used to send out messages with 500 kBit - CAN2 is used to receive data at 1 MBit and this works. Now the user can reconfigure the CAN busses e.g. as follows:Rec...
