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...
Hi all,I am using the Nucleo STM32U575ZI-Q and have been trying to get low level USART with DMA working. Transmitting data works fine as I can see the data using a logic analyser but when I try to receive data either from another Nucleo or putting th...
Posted on March 10, 2016 at 11:19 I am using a custom made STM32F302RE board. I have configured my SPI as follows: hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_DIRECTION_2LINES; hspi2.Ini...
How many samples of a uint32_t can trace log in one second, when trace is set to 2MHz using stlinkv2?
I am using STM32H7A3/7B3 to my project.Currently I use HSE as for the system clock.There is a process when press power OFF MCU will go to STOP mode.My question how to check that HSE has stop and enter the STOP mode correctly?
Hello,I'm relatively new to PCB designing and I've already learned a lot of things, but I'm still not sure about connecting 2 components through GPIO pins. I have IIS2MDC magnetometer and I would like to connect INT/DRDY pin to STM32H747AI. Let's say...
Hi all,I want to measure the power consumption on my board which has a STM32L431CC. Other than the µC, there is nothing left on the board excepted for an RC filter on the NRST pin, I removed the RTC quartz.Inspired by the example code i found, i wrot...
Hello,I'm using a custom board based on a STM32H735 with various GPIO inputs and outputs. The STM32 is packaged as a 0.5mil pitch BGA and the board assembly has been outsourced.I'm able to flash a program on the MCU and debug it by adding breakpoints...
Hello.I am using the STM32F030 for a sensor with a RS485 interface.In my tests, I am sending a 8-bits message (constant value) to the STM32 in a loop. When I look at the data received, the last byte is at the first place, always. There is never any o...
Im attempting to put the cpu to sleep between ticks of timer 15 on a stm32L432, The LED flashs without the Sleep code however it never wakes up from the timer interuptvoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef * htim) { HAL_ResumeTick(); if...
Hi all,We are trying to wire a microphone to the STM32U585. The microphone (T5838) outputs PDM and takes a clock as input.As far as I understand, the MDF peripheral supports PDM interface (as stated in RM046, Rev 4, 39.1), so it is compatible with th...
