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...
Good morning,I am trying to use the STM32-MAT tool to generate some code using simulink models.I have followed the pdf contained within the library, but the STM32CubeIDE project is not automatically created when the build is run in the simulink envir...
Hello there,When debugging in STM32 ST-LINK Utility, there is a problem that device information is written as STM32F07x.I conducted the test with 2 types of MCU and the problematic model is STM32F401RBT.If STM32F401RET is used, it will operate normal...
Hi All,I'm using the following code to set up 4 external triggers and this all works well. What I'd like to do is to be able to change the trigger type of any of the EXTINT at some point in the program. I've tried a couple of things which only resu...
First, the "atomic" port ODR issue when more than one function or task may use the same GPIO port. Is the best thing to do ALWAYS to use BRR and/or BSRR to change the ODR values? From what I've read we need to be wary of an interrupt or other task ch...
How many clock cycles should it take to write to AXI SRAM from the M7 core, assuming that the cache is disabled (and disregarding instruction pipelining)?The reference manual says:"The system AHB SRAM can be accessed as bytes, half-words (16-bit unit...
Hi, i am very new to microcontrollers and have a problem that I cannot understand.I use a STM32F407 on a Discovery board. I set up channel 1 and channel 2 of the TIM2 timer for input capture. As soon the execution jumps into the interrupt handler "HA...
I have soldered MCU chip to a PCB and programed it by ST-Link using STM IDE.when I run MCU using ST-Link it is working fine. But When I use an external DC supply it's showing malfunction, (most of the time not working). I have connected the BOOT0 pin...
Hello,I want to setup a STM32F745IEK6 together with an SDRAM from Micron Type MT48LC8M16A2P-6A.I analyzed the theoretical signal Intergrity for the devices and I had to end because of my question:The setup time of MT48L is required with min. 1,5 ns. ...
Hello, I have a software that has been workingfine for several years on a STM32F100VCT6. However, today we are trying to use thissoftware on the MCUs ref: 100VDT6 or 100VET6. On these 2 new references no programming problem with the same binary file....
