Debug Set to No Debug

Hi i want to know how can i fix the MCU's when i accidentally set the Debug mode to No debug in ioc file as i can not connect it now

Posted on February 19, 2016 at 00:36To share experience with all: STM32F7 has DMAs and caches (DCACHE here in mind). You can use a DMA for Peripheral-to-Memory or even Memory-to-Memory (I use as HW-based 'background' memcpy() ). But you should bear ...

Resolved! STM32G473 QSPI - (W25N01GV) Question about commands (0x34 and 0x6B)

I am trying to make an API for W25N01 flash. I have seen many post about this flash board and followed them. But they have not solved the problem of me not being able to read the data (so either my write function or read function is incorrect). The w...

debug mode with IAR, MCU = stm32f405

I am developing the board with STM32F405 using IAR IDE. the problem is debugging mode. When i use hardware debugging mode on my developing board,the debug mode cannot control the program flow... i command go-one-statement..but go so..many time i thi...

Resolved! USB CDC Example - using the ode to receive and transmit data from USB interface

Hi all I would like to know if I can use the CDC example to transmit and receive data from the windows host without redirecting it to UART

STM32H745 - Code is sometimes slow, but can be fixed by NOP

Hello,I have a rather strange problem on the CM7, where code executes with half or third the speed it should.I have no idea what is causing this, but I know how to fix it: by adding one or several NOPs somewhere in the code.Example: an ISR is taking ...

Resolved! What is the default timer clock frequency of APBx bus?

What is the default timer clock frequency of the APBx buses on an STM32F410RB? I've been considering it to be 16MHz to calculate the frequency of my PWM wave, but it turns out I get half the frequency on scope (is the default clock at 8MHz for timers...

STM32G030 Usart2 Overrun stops further reception

On G030 if an overrun occurs on usart2 (no FIFO available) the reception of further bytes stops.Is this intentional or an known error?

Resolved! Simulate a quadrature encoder on STM32F446RE

Noob here. Using HAL and as much generated code as possible. Ive run into an issue on how to self learn, I've identified what I believe is the solution but nowhere( that I can figure out) in the reference document does it point to this in what I ...

FDCAN_CCCR.Init bit is not getting cleared STM32H723ZG

Hi,I am trying to initialize FDCAN for my project. After the initialization I am clearing INIT bit in CCCR Register. The output what I can see is only CCE bit gets cleared but INIT bit is stuck at 1.Below is my code snippet.void Can_driver_init (void...
