Hello,

my name is Carlo. I'm a student new to STM32 and MCUs in general.What I'm trying to do is to send a 16-bit ADC value through USART to PC, using stm32f0. I found some troubles doing this since USART takes one byte each time whilst ADC1ConvertedValue is 16-bit. I've tried to split a 16-bit value into two bytes but i don't know how to rejoin them to show the actual 16-bit result in the PC.Does anyone have any suggestions ?Thank you very much in advance.Regards,Carlo. #adc #usart #stm32f0

So further presuming little/no PC or C programing experience.

Why then not just output the values in ASCII, with sprintf(), or itoa() type functions, and sending the string of bytes to the PC Terminal application in a human readable form?{   char String[16];   sprintf(String, ''%d\n'', ADCValue);   USART_SendString(USARTX, String);}
