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 ...
I've looked in many places and haven't found a definitive answer yet. The reference manual simply states that reading the GPIO port input register returns the value of the associated pins. Does that mean that an external device has to be driving th...
I am using a STM32L031 on a Nucleo board to sample analog inputs and VREFINT. When I sample the VREFINT voltage after another channel I observe some error that changes depending on the voltage on that previous channel. I assuming that charge is being...
Hello,I have a problem with the SPI protocol (NUCLEO144-STM32H743Z2 board) in a very specific case.The MCU first sends a byte array as a command to the device on the PIS bus, this device interprets the sequence and, depending on the content of the co...
I have a project on stm32f4 with SPL library(standard peripheral library), so I want to switch to stm32f7 mcu and now i want to know is there any SPL library for stm32f7. i couldn't switch to hal library so is stm has any life time code for it or not...
