Changing boot address of CM4 and CM7 in STM32H745 - Dual core
Hello Tesla I need to run M4 from 0x08000000 and then M7 from 0x08100000. Is there any example ? Exactly I v'done my BOOT that runs on M4 (0x08000000) loads the Flash , then jumps into M4 (0x08040000). Now i have to run M7 from 0x08100000, but i d...
Resolved! How to generate a timestamp for datalogging ?
I need to generate a timestamp for data logging, but I'm not sure how to do it.The data packets are received via the UART at a 100ms rate and each packet of data consists of 10 bytes of serial dataByte 0: TemperatureByte 1: Voltage high byteByte 2: V...
Resolved! Can't get oneshot timers to work
I want tim16 to, every 1 second, start tim15 which is a oneshot timer which then does something when the period elapsed.I start tim16 in my main function, which works correctly, but the tim15 interrupt only triggers once, so my output looks like this...
