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...
I want to measure a pulse of 1 ns with input capture of TIM2
Hi Sir/Mam,For our design we are using STM32L431CBY7TR controller which operates at both 1.8VDC and 3.3VDC. For our product we need the Low Power Modes current consumption details for both 1.8VDC and 3.3VDC for our user manual to be mentioned. But in...
Hello folks,I am using a STM32F469i-disco board and trying to read the stored variable from the on-board flash. I did use BSP package to init the QSPI and set it to memory mapped mode. Now, I am facing a weird situation.printf("%x\n", (EXTERNAL[0]));...
I have a project that I am trying to do to learn using RTOS on STM32F407 Discovery board. I am trying to use semaphores on 4 tasks but after the scheduler starts none of the tasks are firing. Below is the code: #include "stm32f4xx_hal.h" ...
Hello,after POR, but before a "switch to SWD" sequence has been sent to the debug unit, what function is PB3? Is is only "Jtag dataout" are can it alreadt transfer SWO data.
I am trying to flash code over CANBUS on Nucleo-F446. I am referring this application noteshttps://www.st.com/resource/en/application_note/cd00264321-can-protocol-used-in-the-stm32-bootloader-stmicroelectronics.pdfSo according to it in Boot mode the ...
Hi,Greetings!I have a Bourns Rotary encoder https://www.bourns.com/docs/product-datasheets/pec11r.pdfconnected to PA11(ENCA)/TIM4_CH1 and PA12(ENCB)/TIM4_CH2.Trying to use the encoder as a input control for user input.This is what I am doing: static...
Hello Friendsi'm new in STM32 i wanna know how to Read Data Byte-by-Byte from uart Rx Circular Dma and save this data in a buffer ? and my challenge is i do not know my input data length and type of that (hex, bin, ascii ,...)theres any sample code ?...
I have a project using an STM32L412. It works fine on my bench power supply, but I made it to run on a piece of modular equipment which has a different power supply - this supply is slower starting. On this supply the board seems to work fine except ...
