Implementation of a Software UART on TMS320C54X |
| |
Abstract: | Because the TMS320C54X haven't UART port,it is difficulty to communicate directly between the external device with UART port and TMS320C54X.Now we introduce the implementation of a software UART on TMS320C54X which can solve the problem easily.Though this method needs no more hardware,it is simple flexible and reliable. |

Keywords: | TMS320C54X UART asynchronous serial communication |
