Hello,I'm trying to connect my MPU6500 to my Nucleo f411re board with the SPI Protocol.The MPU6500 is working correctly because I tested it with an Arduino and it worked as expected.I'm using SPI2 with the Pins PB15, PB14 and PB13.But for some reason...
I have added a bootloader to my code with 0x4000 size. I added SCB->VTOR = 0x8004000 before memory jump from bootloader to app code and I also added SCB->VTOR = 0x8004000 at the first line in the app code main.c . The memory jump works well. My free...
Hey,i want to implement a Modbus TCP IP client on my STM32L432KC board.is there a good libary you would recommend me? iam using a W5100 Ehternet shield connnected via SPI.i want to read/write holding registers on the Modbus master..thanks!
Hello ,I am migrating code from STM32H7 to STM32F4I face the following problems with SPI,1-Hardware output NSS pulses is activated only with HAL_SPI_Init/HAL_SPI_DeInit.2-There should be a pull up on the NSS in order to reach 3.3V and it can't work w...
Datasheet: "Interrupt flag is raised when the content of the Counter register (LPTIM_CNT) matches the content of the compare register (LPTIM_CMP)."Some forums: "Compare match Interrupt flag is raised if CNT >= CMP and not CNT = CMP"(Cf. https://commu...
just comment the code whitch set the pin to enable the predriver device, the interrupt will be normal, hope your reply, thank you.
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...
