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...
We use STM32L496QGI6 with a 512Mb external flash connected to a QuadSPI interface.Principally like the Discovery kit STM32L496G-DISCO (with STM32L496AG MCU and 64Mb flash).We wonder how the STM32 required data hold time during read from flash can be ...
Hello. I used to use the following code for starting a timer interrupt and used to set up the pre scalar and counter such a way I get the desired frequency but now this code is not working. My LED doesn't blink at all. I just wanted to check if the c...
HiI try to run SPI 1 on STM32F103C8 but when i send data i have only SCK signal. MOSI(PB5) is in high state (dont change). SPI2 on PORTA works grate.void MX_SPI1_Init(void) { /* USER CODE BEGIN SPI1_Init 0 */ /* USER CODE END SPI1_Init 0 */ ...
I have defined the enum in lets say x.h file so i can use it in x.c file , but need to use the same enum in y.c so included x.h in y.h and tried to extern it in the same file was give out error, but was working when i extern the same in y.c file. w...
I'm Using an STM32f446 processor and want to read data from the four ICM42688-P sensor at 2kSPS. This sensor is on a common SPI bus. Main criteria is to have the sensors data synchronized so that I get the exact data points from all the four sensors....
I'm using STM32f103C8T6 Blue pill. for IDE is CUBEIDE and using HAL librarywanna receive data from producted BMS module, then additionally control the mcu by received datas. BMS communication module setting is 9600 8-Even-1 by 485 communication.i wa...
Hello,I know that LPUART can wake up MCU from STOP mode. But I'm unable to send data using DMA when entering STOP mode. I use LSE and 9600 as baudrate, so transfer takes a lot of time. I need my core to be in stop mode to reduce current consumption.I...
always stuck in here Error_Handler, and only TxData can load Message successfully twice, so I think it's because of the Callback function is not triggered, so the transmission is interrupted and also RxData didn't receive message.Here is the Callback...
The STM32U5 Errata Sheet (ES0499 rev 5 is the one I am looking at) has errata 2.2.1 which says: "The LSE frequency can be incorrect when PC13 is used as output for RTC_OUT1 or TAMP_OUT2 function". The workaround: "The RTC_OUT2 function must be used ...
Hi i'm trying to get the LPUART (PA3, PA2) pins to communicate with my computer via the serial port, but i can't get anything to work. Here is what i'm trying to use at the moment...Sysclock Config:#pragma once extern "C" void SystemClock_Config(vo...
