#110952 - Implementing a UART through Software |
Hi friends,
i am developing a weighing scale with AT89C55WD controller. my problem is that this controller has only one UART, but i need two. one UART i need for communicating with PC and the other one to receive data from an external device at 9600 baud rate. Is it possible to simulate a UART using normal I/O Pins. If possible can anyone tell what are all steps i need to follow. Thanks regards Sajeevan |
