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...
Hi,We have a question about a system design we would like to implement for our product.We are working with the STMF32F723 MCU and are developing our own HW. We need 216MByte of RAM for our application and would like to implement it with the functiona...
Hi,How can we extract a correct reading of the internal temperature of the STM32L452 in degree C?We currently read a number '141' but this is clearly not the CPU temperature which should be 22-28oCWe have followed the general app note on temperature ...
Hi,I am considering which solution to go for in a new product. To start with, I am going for a 480 MHz STM32H7 with high-resolution timer (HRTIM) for some quick PWM regulation. The regulation feedback is supposed to come from a fast ADC, so I need to...
I am trying to connect 2 NUCLEO-G0B1RET6 boards,using CAN FD. I previously did it using CAN, But now i am trying to connect these boards using CAN FD. So far no success,I want to know if it is possible to do it using CANFD.Kindly help me in this rega...
Hello,my CPU is a STM32H745. I want to flash data into both banks (bank 1, sector 2-7, complete bank 2, while the code runs from the first bank, sector 0+1.I'm using the given HAL-drivers stm32h7xx_hal_flash.c and stm32h7xx_hal_flash_ex.c and found a...
I have an STM32L452 rigged to use an external clock so we can keep the RTC running. Schematic attached.X2 is a clock from SiTime, programmed to be 32.768kHz. C36 is a supercap acting as battery backup. I used STMCube to generate the startup code to f...
Hi! Hope everyone are doing well! I currently encounter a problem and can't solve it. I want to write some pieces of data into a file in a usb-disk and now the Appli_state is constantly idle even I connect the USB-Disk already.This is a test demo cod...
I am using a STM32L471 MCU in a design that may be flashed with new firmware in situ. I'm using SWD as the interface, so the two unneeded JTAG pins (JTDI and JTDO) are used for other purposes. According to the reference manual, JTAG is activated by d...
Hi everyone Question: suppose one sets up a DMA transfer from a Timer1 register to memory so that it gets executed when timer event is raised. What happens first:the peripheral to memory DMA transfer is executed ?or the Timer registers are updated?...
I am reaching out to seek your expertise regarding the DMA transfer issue on SPI that I encountered while using the STM32H743 microcontroller.When an EXTI LINE 0 event (data ready) occurs, attached to the code is a program in which 30 bytes of 0xFF ...
