Dear sirs,I am trying to communicate through CANBUS an F407 and an H757 with external MCP transceivers.The problems I have are:-For the F407, If I set the mode to Loopback, I see with my external logic analyzer that it sends the message in the CAN1_T...

Hi. I'm looking for guidance on entering and exiting Stop mode. L4, but probably applies more broadly. The RMs explain how to enter it, but I'm unclear on RCC effects.PLL oscillators other than HSI or MSI (depending on family) are disabled and desel...
Notice how entire printf lines disappear and how occasionally just portions of printf lines disappear.
Hello, I´m pretty much a newbie, please bear with me.I´ve seen a lot of posts here stating how to code a traffic light using HAL_Delay and HAL_GetTick() but unfortunately none of those I´ve found stated how I can implement different times when a LED ...
Hello! I've bought that kit and I would like to know where I can find the kind of wire which could enable me to power it without using either USB ports or Ethernet one.Below a picture which shows you this input with the mention "5 V power supply inpu...

Hello,In my project I need to generate 1s on, 1s off PWM signal in hardware.First I checked if my PWM works with simple project, and it does.But following AN4776 for N-pulse waveform generation application example - part 1.LL_APB2_GRP1_EnableClock(L...
I just had my first STM32 pcb done and I've been following the reference designs and checked many times everything that there is no shorts etc. However when I power the circuitry 3.3V side draws >200mA and the STM32L4S5ZIT6 does heat up when looked t...
