Hi everybody;
I've built a test circuit. It has an LCD display on PORTD besides serial comm. with computer.
I've only used the LCD before and tested a program. It works well.
After that, I've initialized the RCSTA and TXSTA to communicate on serial bus, but the LCD has obstacled.
Serial comm is working but LCD is not working properly.
I've deleted 3 lines, LCD has worked again. But i dont use receive and transmit interrupt.
I think RCIE and TXIE bits effect the PORTD due to LCD_DATA_PORT is PORTD
**broken link removed**
**broken link removed**
What the mention wrong about that?
Best regards
