STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi,Master:platform: STM32G070CBphenomenon:When the MCU is empty (without any program), connect an external pull-up resistor 10K to the adjustable voltage source on the PA4 pin, adjust the voltage in the range of 4~18V, and find that the maximum clamp...
Hello everyone, I'm facing an issues with STM32H750 custom Board. Configuration: 1. FMC connect 32MB SDRAM 2. 32MB QSPI (Code run at QSPI) 3. 1024x600 16bit TFT-LCD(Framebuffer locate at SDRAM 0xC0000000-0xC012C000) ...
Hello folks,Anyone knows the default CAN clock frequency on STM32H753 MCU when powered on, assuming the CAN bit timing register (CAN_BTR) was not set by FW during the initialization?If this value would be a random, could it be changed depending on re...
Hello,I'm trying to use a STM32H743XI to run a 1280x800px LCD display. I'm using an external 32bit SDRAM (IS42S32200L) running at 110MHz.The active framebuffer (RGB565) is located in the first SDRAM bank and I can display a stable image with LTDC clo...
Hello comunity, I am using the CMSIS DSP library in order to perform FFT to 1412 sample set with a sampling freq of 16.83Khz. I am trying different approaches to find the 16th harmonic after the fft, but i get an inaccurate value. for example, Zero-p...
I USE STM32CubeIDE Version: 1.16.0 when build the project massage arm-none-eabi-size and the hex elf or bin files after download to stm32f107vct6 no actions nothing also i use cubemx last ver for generation code thanks
Hello everyone! I have a very important question about a PCB design that I'm making.I basically have a PCB with a bunch of sensors, a 4Gb eMMC memory and a USB-C connector. Here's the related schematics : - Power section : - Microcontroller (I'm sorr...
Hiwhat is the relationship between the speed of the CPU and the GPIO response. for example, I have a CPU clock of 72MHz and a GPIO clock of 36MHz and I set the pull-up when is this pull-up visible to the CPU because e.g. I would like to read the port...
Good morning,I have an application based on the STM32L475 device that is running in many devices since many years ago. We have observed that, sometimes, some of the devices are resetted --> Here you have the main specs of my device:- Device is workin...
Hi I wanted to make a flight controller using stm32h723zgt6. My question is can this MCU have Usb virtual com port so I can use dfu Mode
