| frank26080115 | 0:bf7b9fba3924 | 20 | @Example description: |
| frank26080115 | 0:bf7b9fba3924 | 21 | Purpose: |
| frank26080115 | 0:bf7b9fba3924 | 22 | This example describes how to use UART in interrupt mode |
| frank26080115 | 0:bf7b9fba3924 | 23 | Process: |
| frank26080115 | 0:bf7b9fba3924 | 24 | UART0 configuration: |
| frank26080115 | 0:bf7b9fba3924 | 25 | 9600bps |
| frank26080115 | 0:bf7b9fba3924 | 26 | 8 data bit |
| frank26080115 | 0:bf7b9fba3924 | 27 | No parity |
| frank26080115 | 0:bf7b9fba3924 | 28 | 1 stop bit |
| frank26080115 | 0:bf7b9fba3924 | 29 | No flow control |
| frank26080115 | 0:bf7b9fba3924 | 30 | - Receive and transmit enable |
| frank26080115 | 0:bf7b9fba3924 | 31 | |
| frank26080115 | 0:bf7b9fba3924 | 32 | UART0 will print welcome screen first, then: |
| frank26080115 | 0:bf7b9fba3924 | 33 | - press any key to have it read in from the terminal and returned back to the terminal. |
| frank26080115 | 0:bf7b9fba3924 | 34 | - Press ESC to exit. |
| frank26080115 | 0:bf7b9fba3924 | 35 | - Press 'r' to print welcome screen menu again. |
| frank26080115 | 0:bf7b9fba3924 | 36 | |
| frank26080115 | 0:bf7b9fba3924 | 37 | Note: If using this example to test with UART1, pls add conversion type (LPC_UART_TypeDef *)LPC_UART1 |
| frank26080115 | 0:bf7b9fba3924 | 38 | because UART1 has different structure type |
| frank26080115 | 0:bf7b9fba3924 | 39 | Ex: UART_Send((LPC_UART_TypeDef *)LPC_UART1, menu1, sizeof(menu1), BLOCKING); |
