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...
Hello, I've been trying to implement a CAN receiver to capture many (~20) messages in quick succession. I've tried to implement the capture of these messages as efficiently as possible, but it seems that messages are still not received. I am usin...
[This is a reconstruction of a thread I've started on Apr 7, 2017, but got lost in the two forum software transitions since then.]In STM32F40x and STM32F41x Errata sheet DocID022183 Rev 8, 2.1.13 Delay after an RCC peripheral clock enabling, there ...
Hi, I am doing something fundamental and cannot get this thing running. n =(TIM1->CNT); z= n + 3; for the first loop cycle 'z' is =3 This is as expected, But as soon as the CNT is increased by 1 the value of 'z' is 4 as shownLOOP COUNTCOUNT...
Hello Community,I am working on a Vibration Measurement system that will be subjected to lifetime vibrations ranging from 10Hz to 2000Hz at approximately 1g with expected lifetime of 2 years with 16 hours daily vibration & 8 hours of no vibration.I'm...
I bought Bluepill devboards from two different sellers, paying extra to hopefully receive genuine STM chips. When I use the Bluepill Diagnostics Tool written by Terry Porter, the tool reports passing on all counts except for one:Declared flash not 65...
Hi all, I'm experiencing a strange issue where every once in a while I am unable to enter bootloader on the STM32G0. I have the option bits set correctly and have a hardware push button connected to both nRst and Boot0. I can normally hold the Boot0 ...
Hi everyone,Is anyone can explain the SLEEPDEEP bit from SCB->SCR with more information than the pm0214 stm32 cortex-m4 reference manual?Controls whether the processor uses sleep or deep sleep as its low power mode: 0=Sleep, 1=Deep SleepWhat i want t...
Hello everybody, I am developing a bootloader that is currently writing to flash, but I am not being able to jump to the written blocks.The bootloader runs from 0x8000000. Built with arduino_stm32.App starts at 0x8009000.I can test the app with the l...
Hi there, i am using STM32F401RE development board and using PWM generation using DMA. I am following register level programming approach and here the issue lies in the DMA settings. Like if I set my PSIZE and MSIZE to 32-bit long and also if my data...
Hello,I'm attempting to set up the CN13 USB port as a Virtual COM Port (VCP) for transferring data to LabVIEW. Unfortunately, I'm encountering an error message that reads "Unknown USB Device (Device Descriptor Request Failed)." I've already installe...
