| frank26080115 | 0:bf7b9fba3924 | 21 | Purpose: |
| frank26080115 | 0:bf7b9fba3924 | 22 | This example describes how to use UART in hardware flow control mode |
| frank26080115 | 0:bf7b9fba3924 | 23 | Process: |
| frank26080115 | 0:bf7b9fba3924 | 24 | UART1 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 | RTS/CTS flow control |
| frank26080115 | 0:bf7b9fba3924 | 30 | - Receive and transmit enable |
| frank26080115 | 0:bf7b9fba3924 | 31 | |
| frank26080115 | 0:bf7b9fba3924 | 32 | UART 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 | 46 | Hardware configuration: |
| frank26080115 | 0:bf7b9fba3924 | 47 | This example was tested on: |
| frank26080115 | 0:bf7b9fba3924 | 48 | Keil MCB1700 with LPC1768 vers.1 |
| frank26080115 | 0:bf7b9fba3924 | 49 | These jumpers must be configured as following: |
| frank26080115 | 0:bf7b9fba3924 | 50 | - VDDIO: ON |
| frank26080115 | 0:bf7b9fba3924 | 51 | - VDDREGS: ON |
| frank26080115 | 0:bf7b9fba3924 | 52 | - VBUS: ON |
| frank26080115 | 0:bf7b9fba3924 | 53 | - LED: OFF |
| frank26080115 | 0:bf7b9fba3924 | 54 | - Remain jumpers: OFF |
| frank26080115 | 0:bf7b9fba3924 | 55 | |
| frank26080115 | 0:bf7b9fba3924 | 56 | UART connection: |
| frank26080115 | 0:bf7b9fba3924 | 57 | Because COM1 port just has TXD1, RXD1, GND, so we need to make external RS232 board to |
| frank26080115 | 0:bf7b9fba3924 | 58 | connect TXD1, RXD1, RTS1, CTS1, GND with PC's COM port. |
| frank26080115 | 0:bf7b9fba3924 | 59 | This external board is not difficult, the schematic can be found in the 232 IC datasheet, |
| frank26080115 | 0:bf7b9fba3924 | 60 | below is just some notes: |
| frank26080115 | 0:bf7b9fba3924 | 61 | - DB9 connector: |
| frank26080115 | 0:bf7b9fba3924 | 62 | + pin 2: connect to 232's T2OUT. |
| frank26080115 | 0:bf7b9fba3924 | 63 | + pin 3: connect to 232's R2IN |
| frank26080115 | 0:bf7b9fba3924 | 64 | + pin 7: connect to 232's R1IN //RTS |
| frank26080115 | 0:bf7b9fba3924 | 65 | + pin 8: connect to 232's T1OUT. //CTS |
| frank26080115 | 0:bf7b9fba3924 | 66 | - UART1 pin: |

| frank26080115 | 0:bf7b9fba3924 | 68 | + P2.1 RXD1: connect to 232's R2OUT |
| frank26080115 | 0:bf7b9fba3924 | 69 | + P2.2 CTS1: connect to 232's R1OUT |
| frank26080115 | 0:bf7b9fba3924 | 70 | + P2.7 RTS1: connect to 232's T1IN |
