How to enable USART1 clock in Arduino Due SAM3x8E?

2

In the file, variant.h, the hardware serial ports are instantiated as:

extern UARTClass Serial;
extern USARTClass Serial1;
extern USARTClass Serial2;
extern USARTClass Serial3;

So, for USART1 you would add the line:

Serial1.begin(9600);

You can enable it by doing below:

    PMC->PMC_PCER0 |= (1 << ID_USART1);
