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...
I am using NUCLEO-H753ZI (STM32H753ZITxLQFP144).Using ADC1_IN3 Single-ended (PA6) and DMA (Mode:Circular),I want to perform high-speed sampling. (1MSa/s or more)Calculated: 3.125MSa/s = 50MHz / 4 * (1.5 + 6.5) (Supplement: clockPrescaler=4, 1.5Cycles...
I have Alarm A and Alarm B both enabled. Alarm A is triggered every second, Alarm B is triggered every minute.They are rock solid for hours to days, but at seemingly random times, the RTC freezes.Here is AlarmA handler:void HAL_RTC_AlarmAEventCallbac...
