kindly advice how can i solve for this error? i had try to define the thing with code below
- CODE: SELECT_ALL_CODE
#define BRGH TXSTAbits.BRGH
#define TXEN TXSTAbits.TXEN
#define CREN RCSTAbits.CREN
#define SPEN RCSTAbits.SPEN
#define TXIF PIR1bits.TXIF
#define RCIF PIR1bits.RCIF
#define TX9 TXSTAbits.TX9
#define SYNC TXSTAbits.SYNC
i this bring me to more error.
