how can i display the temperature value via uart on stm32l010k8t6 please help thanks

There is quite number of example in google. You can take any of them to implement.
like this example:

#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)

PUTCHAR_PROTOTYPE
{
HAL_UART_Transmit(&huart?, (uint8_t *)&ch, 1, HAL_MAX_DELAY);
return ch;
}

printf("Temperature 0 : %0.4f Temperature 1 : %0.4f\n", Temperature[0], Temperature[1]);

Fact is we use l0 series and we use LSE clock with 32khz value and i dont know that we can make "us delay" in this situation or not
We can't use pll because of some issues we have

I will try this code with your library thanks though

I'm not familiar with L0, but think you can try this:

can you help me about this code wanna know in which header file should i define and declare functions?
