Hello...I am using a Nucleo-L476RG dev board along with https://github.com/STMicroelectronics/STM32CubeL4 . I have built the code for PWR_STOP1_RTC and am trying to measure ground current. I have a 10 ohm resistor on the ground side of 3.2V battery...
Hello All, I have STM32F401RE Nucleo board, I have connected the controller as below.However when I hit one Piezo all adc channels are getting triggered.I am continously polling every channels to get the ADC values.1. Is this an hardware issue in ST...
Hello, I am trying to confirm that there is not CAN boot loader for the STM32H750VBT6 LQPF100/144 packages. Attached is the pin out included PH13 and PHY 14 and snipped form AN2606 for the STM32H75xx. Thanks!
Hello All, I came across the daylight saving feature in RTC peripheral of STM32F401RE. I live in a country where there is no concept of daylight saving, hence this is new to me as well. As per the RM of STM32F401RE, there is a automatic daylight sav...
Hello All,We have developed board based on STM32U585ZIT6Q Micro-controller.Clock Frequency - 16MHzReset pin is HIGH and BOOT pin is LOW, Also attached BOOT and RESET Pin timings w.r.t Power supply (3V3)We are facing below issue.1. We are not able to ...
I had been using the instructions gleaned from https://github.com/YetAnotherElectronicsChannel/STM32_CMSIS_DSP for how to use prebuilt CMSIS library for STM32F407 Discovery board.Then I noticed https://community.st.com/t5/stm32-mcus/how-to-integrate-...
As explained in the reference manual RM0503 rev2, §14.10, the MCU has an internal bandgap voltage reference, which can be measured by the ADC peripheral. This reading can be compared to the one performed by ST in the factory (and stored in flash), so...
Hi everyone, I am trying to use LPTIM1 and I2C3 to read the values of a sensor's register every 1 second and save them into a data buffer while in Stop2 mode. What I would like to know is if it is possible to store data sampled at a given frequency ...
Good dayI have created a board that contains a SD card, which works great with L4, F4 and F7 microcontrollers. This board allows me to swap out a F7 uController for a H7 uController since pinout is the same.However, no matter what I do, I cannot get ...
I am trying to use the usb audio to obtain computer sound data and i have blue pill and STM32F746G-DISCO on my handFor blue pill,i add some prints in this functionstatic uint8_t USBD_AUDIO_DataOut(USBD_HandleTypeDef *pdev, uint8_t epnum);but it only ...
