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,I am having Nucleo 476RG board.I configure Alarm A. HAL_RTC_AlarmAEventCallback functions is called upon occurrence of Alarm.Now when I configure AlarmA and then enter standby mode, the board wakes up from the standby mode upon the occurrence of a...
I've been developing a solution around the STM32H750 that requires external flash to run relatively large firmware images, up to around 2Mb.The NOR Flash part used is the Cypress s25fl064l, in QSPI configuration. It has quad read rates of up to 54Mbp...
Hi,I am using nucleo-476Rg board.I have configured RTC AlarmA ad AlarmB for different timings, then I go in standby mode.The board wakes up from standby on any of the alarm occurrence.Can I know whether it is due to alarm A or alarm B. when it wakes ...
Both the Arduino Due and STM Nucleo 32F303K8 resolution is set as 12bits.Digital speed is the instruction set a pin high and then low.In my code I avoided using loops so I coded the instruction 1000 times to get a more accurate reading of the instruc...
I am facing the error ,while upload the code into the board using the stmcubemx and atollic studio.
Hello,I am currently working with the B-L475E-IOT01A board. Through bluetooth I would like to use the mode in which I send data periodically and an external device, when it enters the transmission range, can read this data.So I was wondering which of...
Hi,I've been trying to synthesize different waveforms with my F446 DAC. Three things have come to my attention here, which I can't explain. First, when I am using the full range of the DAC with values from 0 to 4095 the signal gets distorted like thi...
Hello,I have a strange problem... We have a bunch of equal boards (STM32H743XIH6) from manufacturer and some have temperature dependent problems (3 of 20). The problem seems like a software problem, but many software changes couldn't reproduce this.I...
I have two stm32 on my board. I send serial data from stm32f407 to both max232 and stm32h743. The output data from the max232 is correct. but when I debug the stm32h743 input serial data, its data is incorrect. what is the problem?
