7 2. Basic operation 2.1. Download programs You should download program to the board to run it. The demo programs of the present development board can be found from Waveshare web site or Waveshare Wiki site. Flexible programming methods are supported by the onboard LPC chip. That is, it can be programmed by ISP, JTAG and SWD. You can choose different programming methods, however, using a different method means a different programmer may be required. Some of which are not contained in this product. For example, if the chip is programmed by JTAG or SWD, a ULINK or other JTAG or SWD supported programmer is required, but it is not contained in this product. If the chip is programmed by ISP, the LPC ISP (mini) board in the package is enough. ISP programming method is mainly introduced in the present document. If you choose other programming method, please see the related manual. Here the software Flash Magic is used to program hex files. 1) Set jumper ISP JMP to on. (Some development boards have none of ISP JMP, so it is no need to set on ISP JMP of these boards.) 2) Connect the USART interface of the board to the USB port of a PC with LPC ISP (mini) board. 3) Install software Flash Magic. 4) Power up and run Flash Magic. 5) Set the software: - Click Select and select LPC COM Port: choose the COM Port according to which port has connected to the USART. - Baud Rate: choose appropriate baud rate as (Download speed and stability depend on baud rate) - Oscillator (MHZ): input 12, according to the onboard crystal. - Check "Erase blocks used by Hex File" and "Verify after programming"; 7

8 - Open Advanced Options -> Hardware Config -> check "Use DTR and RTS to control RST and ISP pin" -> input T1: 50 ms T2: 150 ms. (A shorter time input makes downloading faster. However, it can also cause instability.) As shown in the following figure. 8

9 - Click Browse and select the Hex file for programming. - Click Start to start programming. (If any error occurs, please reconnect the board, reset it, and restart the software.) 9

10 - Check the programming progress bar, at the bottom of the window, to confirm if finished Serial communication Each step, concerning to serial operation, requires serial monitor software (PuTTY, securecrt, etc.), the software should be set to: Choose corresponding COM port. Baud rate: Data bits: 8 Stop bits: 1 Parity: None Flow control: None 10

11 Each demo for the product, as long as any UART communication used, is set to ISP+UART0 interface by default. In other words, a TTL to serial module (here a LPC ISP (mini) module can also be used as TTL to serial module) should be connected to the ISP+UART0 interface for using these demos. As shown in the following figure: 11
