4.4 Program Download

This section describes how to download an application to the board, i.e., to the LPC11U37.

1. Connect a USB cable between J9 on the board and the PC. See Figure 2 to locate J9 (upper

left corner). J9 is the LPC-LINK debugging interface (the debug interface of LPCXpresso).

2. Make sure that the LPC11U37 is in a mode where the debugger can take command over the

processor. When the LPC11U37 is in a low-power mode it sometimes prohibits the debugger

from connecting to the processor. The simplest way is to place the LPC11U37 in ISP/bootload

mode. While resetting the LPC11U37 press the ISP push-button. See Figure 2 to locate the

reset and ISP push-buttons (in the middle of the lower edge, right of the Lithium battery).

a. Press both Reset and ISP push-button

b. Release the Reset push-button

c. Release the ISP push-button

d. The LPC11U37 is now in ISP/bootload mode. LED1 will light weakly constantly. This

is a sign that the LPC11U37 is in ISP/bootload mode.

3. Make sure that the latest version of the LPCXpresso IDE is installed on the PC.

4. Import the sample application software package into the Eclipse workspace. This package

can be downloaded from the Embedded Artists support page after registering the product.

The demo application is one of the projects in the sample application package.

1) Click (to select) main project
