STM32 MCUs Products

I am working on cortex M4 (STM32F407) with ucOSII, now I have found low probability that enter the hard fault exception, in the hard fault hanler we can get the PSP address (task stack) , but the LR/PC value stored in the stack are 0xFFFFFFFF.

typedef struct{ UINT32 R0; UINT32 R1; UINT32 R2; UINT32 R3; UINT32 R12;   UINT32 LR; UINT32 PC; UINT32 IPSR;  }STACK_DATA_TYPE;

How do copy sections from FLASH to RAM? I am using the scatter file but not the linker script file. Can anybody help in it?

UART interrupt recieve Turning LED ON and OFF from terminal by using "Command+Enter"

I want to Turn On and OFF LED by Command "LED ON" or "LED OFF". When i write command "LED ON" in the command terminal like Tera Term the LED should be On. I used here string comparision to compare if the given command is same as "LED ON" or "LED OFF"...

STM32L1 Stop mode usage

Hello, I have problem with entering to the stop mode againHere is my function to configure stop mode, used once before main loop, and it's ok after that MCU goes to stop mode and power consumption is low.void EnterLowPowerMode(void) { //used just onc...

Have I to use an I2C pin to write into EEPROM ?

I ask this question because I am already using all the i2c pins for my lcd screen and I need to write in EEPROM and it seems that I need to configure a I2C to use the hal function to write ...

I am using STM32L475 at HCLK 72MHz, at this clock the number of wait states required is 4 but I configured for 2 wait states and ART enabled. At this condition, my controller performance is good w.r.t timing taking.

I increased to 4 wait states and tested and performance is not reaching w.r.t time and taking more time to complete the functions. Do I need to increase to 4 wait states?

STM32F779NI CAN peripheral programming with STM32-MAT/TARGET Simulink blocks

Hello, I want to use STM32-MAT/TARGET to generate code for STM32F779NI CAN peripheral in interrupt mode to receive message over CAN bus. CAN IT block is having option only for TX, Rx and ESR interrupt. There is no option on CAN IT block to configure ...
