I'm working with the h743 family and I'm trying to figure out how the HSLV (High speed Low voltage) I / O's work, because I don't want to use this option to avoid damaging the MCU, since my power supply is 3.3V. In more detail, I want to set FDCAN1 o...
While looking at datasheets of various STM32s and AN4899 (STM32 GPIO Application Note) I was trying to determine the GPIO absolute ratings. There is a consistent value of 25 mA per pin in Absolute Maximum Ratings in all datasheets, but no maximum cap...
There are examples on how to set up SDRAM on STM32F769-DISCO board but I found no comprehensive example of what I think should be the default setup for this board: SDRAM configured for heap, stack and 2MB LTDC buffer reserved.So far I figured out SDR...
So I was handed code that breaks when debugging, but to fix the breakage breaks a power control on the board. Rev A only has this problem but Rev A is what I'm stuck with . Nice, right? So I need a way to tell at run time whether the debugger is att...

Hello, I've just received the STM32L475 Discovery kit IoT node. I connected the board through USB cable to my laptop (the JP4 jumper is connected to 5V_ST_LINK) and the power supply LED (LD5) is blinking. Also the board is not visible from laptop (I ...
I am using a nucleo board to develop some FW (NUCLEO-L073RZ, with STM32L073RZTx), but I wish to use the device (STM32L011G4) in the final product and use the nucleo board to program. I am not sure which pin on the SWO signal to.Thanks,Ashraf
I want to implement a CAN bus and I have the following boards:NUCLEO-F401REWaveshare RS485/CAN Shield (https://www.waveshare.com/wiki/RS485_CAN_Shield)I have seen that CAN interface is not avaliable in CubeMX for my nucleo board, so I have some quest...
Hello. I use STM32G474VET6.I want to use the comparator output as an external event for the timer. The output of the comparator (event) must be inverse (the POL bit is set in the COMP_CxCSR register). However, according to the logic of work, I see th...
