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...
Hi is it possible to use a 14.7456MHz crystal with a STM32G031 (LQFP32). If I'm right it is not possible at the data sheet, there is no OSC_OUT for this package. Or is the option missing in the data sheet? We need this crystal for an IO-Link applicat...
I want to use JSON library to send customized data to serverWhere i can get the library?Micro controller connected with modem (sim900a)Motive is to how to send Json formatted data from st controller to server.*My controller is :STM32F042G6
Hi,I am using STM32L073RZT6 board, i am use the wakeup pin PA0 and PC13 together on the standby mode but in the standby mode, PA0 wakeup pin is not working. I am enable both the pin before go to standby mode. The power Control Status Register arePA0 ...
HiI develop my own bootloader for STM32L152VC. The bootloader works, but I found something wierd.When the device is turned on and there is no need to write the flash the program jumps to the application and everythings works properly.When I write the...
I am using stm32f407 discovery board. My printf function works fine but when it comes to printing numeric values HardFault(Bus fault) occurs. It prints alphabets perfectly fine but cant print numeric values. e.g. printf("UFSR=%x, *pUFSR); It prints ...
I am trying to do download bin file through uart (serial trans)I have experience which downloaded using flash loader demonstrator with STM32F4 series.so I thought it could be easy to do with STM32G474 and I found datasheet about option bit can choose...
Hi,I'm working on a STM32L072 project, with an environment composed of arm-none-eabi-gcc compiler version 10-2020-q4, make and Eclipse IDE.I'm having trouble with a hardfault occuring in libc_init_array function call in startup file. Using disassemb...
My datasheet (STM32F103VC) states the Vbat current draw is 1.4uA. Is there a way to reduce this? I only need the backup domain for RTC/LSE. I know there are many backup registers as well. Could I turn these off to reduce current draw?
There are any way to each time that I build the project, the changes made at the second linker script will be done? The main linker script is STM32F746ZGTX_FLASH.ld, and the other is called MEM_0.ld, and it's in another folder inside the project. Tha...
Hello, all. First of all, thank you for taking your time for reading this and helping me out.I am using STM32H743ZI Nucleo board, preparing the project for a power electronics application. Before any control algorithm I'm checking that the Interrupt ...
