Why USART stops with ADC? STM32F103C8

Hi to everybody!! I have a problem with an STM32F103C8 board "Blue Pill". I have configured the two ADC converters to make measurements, I also have configured the USART1 to send and receive information from and to the computer. (I can turn on a LED and I can see a printf from the MCU) Each one works good, but when I add the both functions to the int main(), the USART stops to work, while the ADC keeps working good. I know that the ADC keeps working because I can see the data in the debug tool. To send and receive serial information I use a software named DOCKLIGHT. 


I hope someone would help me to know if I have to configure something in the KEIL uVision 5 to program this board. Thank you very much
