I there a way (device or API) to control STM32 resources via JTAG or SWD without the need to downloading a custom program? For example, setup GPIO pin with pull-up and direction and then write value. In addition, be able to perform more advance sce...
Hi all,I'm unable to switch the internal regulator from the default LDO to the SMPS on the STM32U599NIH6Q. The function "HAL_PWREx_ConfigSupply" timeouts.The same binary file, when flashed on the two different STM32U5 dev kits (NUCLEO-595ZJ-Q and STM...
Hi, What is acceptable ripple voltage on power supply pins on stm32? I am using DC/DC converter and have 100mVpkp at the output (+3.3V). I tied VDD and VDDA pin to one power supply as I am not planning to utilize an internal ADC. I am just planning t...
I want to switch clock source for decreasing power consumption(WakeUp->MSI->HSE->MSI->STOP2->WakeUp->MSI->...). I use HSE(12MHz) for SYSCLK through PLL(24MHz).MSI is set 24MHz.I have three probrems.HSERDY doesn't RESET when disabling HSEAfter enter...
I am configuring can and sending data to other stm32f103c8 but when I connect the can H and can L on the channels of oscilloscope I don't get any signal. What could be the problem?,i used mcp2551 transceivercode for transmitting data :/* USER CODE BE...
Following code has squiggly under bars in printf statements:Is there a simple way fix these compile errors please:This program is from Embedded System Design with Arm Cortex-M by Cem Unsalan et al,chapter 3 page 50.
Currently using STM32L496.Pressing the button long key enters STOP mode as shown below.HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);Additionally, you can exit STOP mode by pressing the interrupt button.For reference, after e...
Good morning everyone, after collecting some data and storing it in various buffers, I am trying to write them to the serial port for further processing. I am experiencing issues as I can see that something is being written to the serial port, but no...
Hello all,I developed a board based on the STM32U585RIT6 (without SMPS package) based on the STM32U5 guidelines.I've encountered a problem during tests: When I turn on the MCU block on my board, the MCU draws >600mA of current.My first reaction was t...
Hi,I developed my first board with a STM32L431RCT6 (80Mhz) but sometimes I have problems with an external 8MHz crystal (HSE switches to HSI). I configurated the peripherals and the clock with STM32CubeMx.This is a clock configurator page (I enabled C...
