I have existing working code which uses uart and some GPIO functions. Its main.h has,#include "ll_common.h", #include "stm32h7xx_ll_gpio.h", #include "stm32h7xx_ll_usart.h"and few more ll headers.Now I need to add I2C functionality to the code. I go ...
I want to use scanf function for usart with dma please help me for that.I need to receive a string through scanf but the string size will differ each time .
i am using stm32f746 controller.i want to upgrade fw using internal eeprom i store hex file in eeprom and after i download in flash please have any guidance plz provide us
Hello,I am using system workbench to generate a project not using the HAL libraries, bare metal as they say. I have done quite well thus far although today's headache concerns the use of sprintf. It is crashing my processor (STM32L476RG). I can get i...
Hi,I am trying to emulate a EEPROM with my STM32F103 as a I2C slave. I'm using STM32CubeIDE 1.0.2.The chip that will request data doesn't write data to the EEPROM, so I can use only an array to save the data in the code. And it cant have any code in ...
Hello everyoneSo I'm trying to read and write 64 byte long list from FT24C16A. I'm using STM32F103C8T6. So first picture displays I2C init for uC. Not problem here. I'm using 3.3 V.//---I2C_init---// static void MX_I2C1_Init(void) { /* USER CODE ...

Dear All,Board: Nucleo - H745ZI-QI want to store few bytes of non volatile memory, for which I learnt that I need to use EEPROM emulation code. I went through the code given as part of STM software in en.stm32cubeh7_v1-7-0\STM32Cube_FW_H7_V1.7.0\Proj...
Hi,I'm using a STM32F4 Discovery board which has a STM32F407VG with a LIS3DSH accelerometer which is connected by SPI. I'm trying to read a register from the accelerometer and I tried writing the address of the register to SPI->DR. But SPI->DR shows ...
