UART will print welcome screen first, then UART3 keep reading the income irda signal and output to 8 leds bank the received value. Note: If using this example to print with UART1, pls add conversion type (LPC_UART_TypeDef *)LPC_UART1 because UART1 has different structure type Ex: UART_Send((LPC_UART_TypeDef *)LPC_UART1, menu1, sizeof(menu1), BLOCKING); @Directory contents: \EWARM: includes EWARM (IAR) project and configuration files \Keil: includes RVMDK (Keil)project and configuration files lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example makefile: Example's makefile (to build with GNU toolchain) uart_irda_receive.c: Main program @How to run: Hardware configuration: This example was tested only on: Keil MCB1700 with LPC1768 vers.1 These jumpers must be configured as following: - VDDIO: ON - VDDREGS: ON - VBUS: ON - LED: ON - SPK: OFF - Remain jumpers: OFF UART connection: Add in a simple hardware: (1 infrared receive led, 1 150R resistor) - An infrared receiver led which has its anode connected to 3.3V, cathode connected to a 150R resistor. The other end of this resistor connects to GND. - Connect a wire between P0.26, SPK jumper, and this infrared receiver led's cathode. Running mode: This example can run on RAM/ROM mode. Note: If want to burn hex file to board by using Flash Magic, these jumpers need to be connected: - MCB1700 with LPC1768 ver.1: + RST: ON + ISP: ON - IAR LPC1768 KickStart vers.A: + RST_E: ON + ISP_E: ON (Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with LPC1000CMSIS project" for more information) Step to run: - Step 1: Build example. - Step 2: Burn hex file into board (if run on ROM mode) Also burn the transmit example hex file to the other board. - Step 3: Connect UART0 on this board to COM port on your computer - Step 4: Configure hardware and serial display as above instruction - Step 5: Run both examples Point the infrared transmit led to the infrared received led66 Observe the 8 leds bank and compare with the value send out by the transmit example. (Pls see "LPC17xx Example Description" document - chapter "Examples > UART > IrDA - Receive" for more details) @Tip: - Open \EWARM\*.eww project file to run example on IAR - Open \RVMDK\*.uvproj project file to run example on Keil
