I have to write code to write/read to/from an ATMEL 24C256 EEPROM which has a 7-bit address and the eighth bit is for R/W. I guess the MCU should be configured for 7-bit addressing (ADD10 = 0) but in this case how does the MCU write the eighth (R/W)...
Hi guys, i have this type of errors when i try to connect stm32f446re with simulink. I hope that someone can help me to fix the problem.
Hi,I am using STM32L07XXXI am reading/writing and external eeprom using I2C" but I2C communication fails many time ". and system hangsDoes this function run needs to be atomic ?But using __disable_irq and __enable_irq effects HAL_GetTick() ?Can i ena...
Hi,I'm trying to write and read to/from M24512-R EEPROM.Seems that everything is fine writing and reading because HAL return is HAL_OK, but allways I've reading 255 value.My code:int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ ...
In mat/target uart receive block, the message length must be definite and the block waits until the input data length becomes equal to the defined length. if one or more bytes may loss in communication or the message length may be variable, so the bl...
HiI develop my own bootloader for STM32L152VC. The bootloader works, but I found something wierd.When the device is turned on and there is no need to write the flash the program jumps to the application and everythings works properly.When I write the...
HelloI am currently working on a project were we would like to use the STM32F303 board. We would like to debug it using the external execution mode of Simulink, but I am having problems for generating the code.I have been following the "STM32_MAT-Tar...
According to 93LC66 communication the 93LC66B variant is a rotated variant. How to establish communication between NUCLEO-G474RE and this EEPROM using SPI ? I've tried many approaches but none worked, always get 0 from EEPROM but it should be FF, I t...
Hi,I am using the STM32F303CB microcontroller and STM32CubeIDE (1.6.1) to write data in EEPROM - AT24C512 and read respectively.I haven't used HAL libraries, I Wrote I2C_Init - To initialize I2C (Fast Mode 400 KHz), I2C Write and Read Functions.Some...
While debugging my code, instead of step by step execution, if I run the execution continuously, after some time the TrueStudio loses connection with target.Can some one help me in resolving this issue?
