Resolved! Watchdog functionality in Sleep mode for STM32U535CET microcontroller
Hello,I am facing reset problem when I am waking up from Sleep mode. I am using WWDG in Software mode.APB1 Frequency as 40MHz. COnfiguration of WWDG:hwwdg.Instance = WWDG;hwwdg.Init.Prescaler = WWDG_PRESCALER_128;hwwdg.Init.Window = 127;hwwdg.Init.Co...
STM32F446RE CRC mismatch
Hi, I am following a video to write a bootloader that transfers the application code serially into the STM32F446 controller. The video originally presents the STM32F7xx series controller, but I am applying it to the F4xxx series. I have modified the ...
NUCLEO-H533RE E5V external power supply issue
Hi, We have bought the NUCLEO-H533RE board and I tried to power it via E5V by connecting the Arduino Minima R4 board 5V power output into E5V and GND signals in pins 6 an 8 respectively. I instantly noticed that the LED LD3 is lit with green, but the...
Resolved! NUCLEO-H753ZI voltage output
Hello, Can I output an adjustable voltage ranging from -10V to 10V using the h753zi development board? I found something like a "PWM to 0-5V/10V DAC Module."Would I need to use such an external module or build an additional circuit externally to achi...
Programming NUCLEO-F303ZE with JTAG
Hello, I made a code to readout all the STM32 ADCs. The code works.I want to run it on my Nucleo-F303ZE with JTAG ProVision, but it dont work.What did I do wrong?I connected it like this:JTAG NUCLEOTCK => SWCLK-JTCK (PA14)TMS...
STM32f446re Altium
Hello everyone, I’m currently working on a project involving the STM32F446RE as the main microcontroller. It’s my first time using Altium Designer, and I’ve been searching for the footprints and schematic symbols for the components I need. While I’ve...
