I am using nucleo L476RG with DS2482-100, also 1-wire DS28EC20 is connected with DS2482-100. First I created the project with CubeMX, then MX_I2C1_Init() My first question is: how to find the I2C address, which I need to fill hi2c1.Init.OwnAddress...
Hi,I'm having trouble, because I got when I defined a second array which I need for processing a image with the STM32F429ZI Microcontroller a message that I have a RAM overflow.When I now define a smaller array, like uint8_t image[240][320] my whole ...
I'm having a hard time tracking a source of the hard fault occuring in my program written in C++ for the STM32F405 microcontroller.I only use three sources of interrupts in this project - two timer interrupts (TIM2 overflow happening with 36kHz frequ...
I'm working with an STM32L073RZ on a custom board. The board is in STOP mode and I have a pin (PB_5) configured as a rising edge interrupt. I'm using ARM Mbed OS 5.12.0 but primarily working with the HAL API. The code I have so far is below. It simpl...
We are currently using STM32F427VIT6 in our design.We would like to have IBIS model for our simulation purposes.
How to switch the execution of the application code from external flash to internal ROM in STM32H7xx microcontroller?
Hi I am trying to write a code using STM32f103r8t6, i have installed IAR for Arm v8.40.1 i started to create a project but i could not find any library files. and then by downloading an example file i got the library files as i tried to complile i m ...
I detected that ART accelerator and prefetch is not enabled. Why for loop gets slower if if I switch both on ? /* USER CODE BEGIN SysInit */ #if defined(FLASH_ART_ON) // enable ART for Flash (x8 Booster) int FLASH_ACR_REG=0; volatile unsign...
Hi!I have a basic code - blinking LED code which uses onboard LED (PC13). The problem is that it doesn't toggle at all, it just stay switched on and doesn't go off after delay. I've tested that code in debug mode and everything worked fine, it toggl...
CPU 210MHzIf you run IRQ code from flash you have about 5 times more cpu cycles as needed (7WS)if you switch on ART accelerater and prefetch: for loop gets slower no influence on IRQ latencyyou could not run code from internal SRAM because of missin...
