I used 7bit device address as 0x51. considering A16 bit as 1 for above 64k memory locations.I am able to write though. and I confirmed it by writing to above 64k memory locations and reading it by using 7bit device address as 0x50 and doing sequentia...
on those rising edge with interrupt and i need to count each time.secondly i need to use another timer and set its frequency to 100KHZ with interrupt mode. i need to use counter to count at each interrupt. thirdly based on that counter i need to cal...
hiI want to locate a string in an other string and then mark its position with an 'X'. here is the code#include "main.h" #include "adc.h" #include "dma.h" #include "i2c.h" #include "usart.h" #include "gpio.h" #include "stm32f1xx.h" #include <string.h...
I've been stumbled upon this issue for a week now.On STM32H725ZG, ADC3 circular DMA is not working.A test codelet below, designed to demonstrate the issue, repeatedly takes 12-bit readings from PC0 (ADC123_INP10) and PC1 (ADC123_INP11) with ADC1 or A...
I am using the advanced timer TIM1 on STM32L476RG MCU. I have configured the timer in slave reset mode as given in section 30.3.26 of the reference manual. The counter resets every rising edge. I want to use this mode to measure low frequencies such ...

Hi, Below is my requirement: Need to send a DAC sample every 2ms (on 32KHZ clock) Every 12 sec will do an access to external flash to copy a block of memory (on HSI clock)how can i accomplish this? am new to microcontroller, can anyone help me with s...
I'm using follow code:volatile unsigned int *DWT_CYCCNT = (volatile unsigned int *)0xE0001004; //address of the register volatile unsigned int *DWT_CONTROL = (volatile unsigned int *)0xE0001000; //address of the register volatile unsigned int *DWT_L...
hi I want to enter the debugger mode and then run the whole code by clicking 'Run' button or F5. but every time that I click 'Run' it just goes one step forward and it even enters inner functions...what should I do?
