Block for sending values through the UART

[anso-engineer]

Hello, I am trying to wire STM32F103C8T6 with DS18B20 sensor and I realize that after some actions it stopped to work and no data through the UART sent:

 

 

 

  Probably it's not big deal, but I have no idea why UART completelly blocked and sending no information.
Current version of this code based on the materials of:

You'll have to debug it. Your output buffer isn't really big enough to hold the string and NUL termination.

Try something more like

int number = 123;
uint8_t numarray[8]; // make sure you have enough space
...
while(1)
{ // sprintf returns the string length
  HAL_UART_Transmit(&huart1, numarray, sprintf(numarray, "%d\n", number), 1000);
}

I extended buffer size but unfortunately nothing changed...
Can be something wrong with configuration I applied?

No idea

Do you have actual hardware? Can you put a scope on the signals, and use a debugger?

Check the code that configures the pins.

Do you have a supervisor or trainer?

Do you have any other working example in this environment?
