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...
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...
Hi,I´m trying to develop an external loader ("EL") for my custom combination of an STM32G070RB with an external Flash in single SPI connection (M95P32-I). I´m using:- SMT32CubeIDE Version: 1.13.0- STM32CubeProgrammer 2.13.0My EL is being accepted by ...
OK, this is perhaps a fairly stupid question but I do not get it.I have an analogue voltage in range -5V..+5V and wantto measure it with the ADC of an STM32F446. The ADC-input works in range 0..3.3V.I have the feeling I can do that with a simple, res...
Hey!I'm trying to use ST-LINK/V2-1 from Nucleo to program and debug my board. I removed the jumpers from CN2 and connected CN4 to my board according to the manual:Problem occurs when I tie NRST of the CN4 to the STM32 on my board - in this case "DEV...
