Can't modify SCB register and Ethernet hard fault
Hi All, I'm using STM32H743ZI2 Nucleo board to connect to internet but I have a hard fault error.I'm try enable MMARVAILD bit in SCB->CFSR to hold valid fault address (SCB->CFSR |= (0X1UL<<7);) but it's still 0 after set command.Please help me to che...
Dynamic Memory Allocation causes hard fault
I am trying to implement a function that extracts mfcc of the retrieved sound. I am using Hanning window. I actually am applying dynamic memory allocation twice. First allocation works successfully. Second allocation however somehow takes me to hard ...
Every time i getting the same error and i cant fix it . I am trying to write my uart communication as a header file even if i used the extern but it doesnt work , Can somenone help me how to write properly ?

What is the correct initialization order of GPIOs as alternate function output and associated peripherals in order to have full control over the state of the output pins?
We are currently working with STM32F103VE MCU and we have a dilemma about the order of initialization GPIO pins as alternate function outputs and associated peripherals. The goal is to have full control over the pin states. We have checked order of i...
CAN 2addres to 2 massive.
good afternoon friends.I am learning to work with SUN.I want to receive parcels from 2 addresses. In principle, it works, but the values from two addresses are written to one array.How to make it so that values from different addresses are written ...
How to program the FLASH_OPTR register in stm32G0B1KE through i2c in-application programming?The offset mentioned as 0x020 for FLASH_OPTR register.what is the offset referred here?
How to write the register values using offset address in flash memory?what is the base address to consider for offset values?
Resolved! How does AHB Prescaler value fill? const uint8_t AHBPrescTable[16] = {0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 4, 6, 7, 8, 9};
I want to know what kind of value we fill in this and what affects the AHB Bus please make me understand.const uint8_t AHBPrescTable[16] = {0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 4, 6, 7, 8, 9};I tried to find out but only figured out the value of 1 to 9 i...
Resolved! Bitwise
"I'll delete this question once someone answers it, as it is not relevant".Why in second line did some one write ch & 0xFF? ch limits are already 0 to 255 right?
STM32G4 op amps (>1) as inverting PGA with mid-point bias applied to non-inverting inputs - tie non-inverting inputs together?
Application needs to use all three (in STM32G431) op amps as inverting PGA handling ac-coupled signals. As there's no internal option to supply mid-point (VREF/2 with a decoupling cap at the device pin) to the non-inverting inputs of the (3) op amps ...
