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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
There, I am starting this STM32 Board, which I dont know the exact type of STM32 to choose, I need to replacing old machine board (its microprocessor base) with 10 of weight sensor, and 20 stepper motor, and 2 communication and 1 additional output, P...
How does STM32F207 turn off all interrupts
I am using stm32f4xx, and I am using UART with DMA normal mode. I have a problem with the Transmit Completed state, When I using the TxCompletedCallbacks I get hard fault error so I learned it does not using with normal mode so I am trying the Transm...
I want to configure the RTC interrupt for every 1s in L475. Since all RTC interrupt are routed through EXTI, is it possible to generate the interrupt periodically without depending on external signal? Something like second interrupt (SECIE) in STM32F...
We are working with STM32H750VBT6. Our project works with an external QSPI flash. We planned to put our bootloader in STM’s internal flash and our firmware in the QSPI flash. We need to protect the internal flash (bootloader) for reading from the ext...
I am trying to run a simple program that can read in data from a potentiometer through ADC. The pot is connected to PF10 or A5 on the nucleo board. My code is below:When I run this it prints "Value is: 32767" once then stops. Because I am in conti...
Hi everyone,I'm working on projet which does the acquisition of signal continuously with sampling frequency is 25kHz. The length of acquired signal is about 1s (25000 samples), then some signal processing will be applied on this signal to obtain some...
Dear STM Community,I am a Fresh learner of STM32 technologies. I got myself an STM32F429 Discovery Kit.As expected, I tried to do Led Blinks on my board since it is the hello world of this technology.However, I couldn't turn on the LEDs on board. I c...
i read data sheet of lis2dh and lis3mdl. i am using st linux driver to read raw data of accelerometer and magnetometer. Now when i set sampling frequency 1600 for accelerometer i get data of x axis at 40 ms. when i set sampling frequency 80 for ma...
