syntax is the bane of my work...

I don't understand why this would compile and work for one project but not another...const char Menu[40][32] = { "\033[91;2mShow Menu\033[93;2m <space>", "\033[0m ", "1 Read Flash status" };   char * ptr = &Menu; <- fails here [C...

SPI master send simle data error

Hi, do you know how is the simplest code to send data from stm32(master) to arduino (slave) through spi.I tried to write my own code, so here is the sktech ofmy code :#define SPI2_Funct 0x05 // This is a function of GPIO AFR#define CMD_LENGTH  2#defi...

STM32H753I-EVAL SDMMC cubeMX problem

Hello, I am a total newby for what concerns stm32 programming and this question may be stupid.... I am using a STM32H753i-eval board and will need to use fdcan, lcd, SD and a few more peripherals. For this reason I started my project using STM32cubeM...

I am using STM32L432KC Nucleo Board. My Vref is connected to 3.3V but I wish to limit my DAC output from 0 to 1 V. How I can achieve this?

I understood that for FLASH of STM32L05x 1 bit error detection and correction is provided. What happens when more bits are corrupted?

Basic question regarding timers and generating a simple delay

Hi there,Let say I want to generate a 1 ms delay using a timer. I set my prescaler to have a 1ms granularityTIMx->PSC = (uint16_t)((SystemCoreClock / 1000U) - 1);Now if I want to generate a 2ms delay I usually do it like this (assuming the UIF flag i...

STM32F746-Disco SDRAM problem

Hi,I have problem with the test of SDRAM memory. I use STM32F746 Discovery kit where is MT48LC4M32B2 memory.  SDRAM size is 128-Mbit SDRAM but only 64-Mbit is accessible on kit. So I try to test the entire 8MB SDRAM memory. Unfortunately, when the la...
