1. Introduction
Simple Window Interface Manager (SWIM) is a basic graphics library developed for the NXP LPC products. It can be also be used with LPC controllers that do not have a dedicated LCD interface. The SWIM graphics library allows developers to quickly and easily implement a system with basic graphics support. Project examples for IAR EWARM, KEIL MDK, and Rowley Crossworks toolchains are provided as part of the package. These projects are directed at the following target platforms: · LPC3250 from Phytec: http://www.nxp.com / redirect / phytec.com · LPC2478 from EA: http://www.nxp.com / redirect / embeddedartists.com · IRD Platform from NXP: http://www.standardics.nxp.com / support / boards / ird The example projects demonstrate how to use the library and will help users get familiar with the library calls quickly and efficiently.
2. SWIM features
The following section describes the main features and functionality of the SWIM library. In addition, the library code is well commented and an associated API document for the software calls - SWIM v1.0.pdf - is also available. Some of the main SWIM functions are briefly summarized in the following subsections.
2.1 Graphic primitives
2.2 Image support
2.3 Font support
· Helvetica 10-point proportional font · 8x16 proportional font · 8x8 proportional font · Fixed 5x7 proportional font · Windows FreeSystem 14x16 Font

5. LPC3250 Phytec
The LPC3250 Phytec system is made up from three boards: the phyCOREARM9 / LPC3250 System on Module (PCM-040), the phyCORE-ARM9 / LPC3250 Carrier Board (PCM-967), and a optional add-on LCD - Hitachi 3.5" QVGA TFT-LCD with integrated touch on adapter board (KLCD-011). The complete system is shown in Fig 3.

Fig 3. Phytec LPC3250 Platform
The phyCORE-LPC3250 module is populated with the NXP LPC3250. State-of-the-art power management, Vector Floating Point Unit (VFP), and rich peripherals such as USB OTG, Ethernet, and integrated LCD controller make this device the ideal candidate for embedded applications requiring high performance and low power consumption. The onboard MMU supports major operating systems, including Linux and Windows Embedded CE. Other chip-level features include 7 UARTs, SPI, I2C, a real-time clock with a separate power domain, and NAND Flash and DDR memory controllers. These features make the devices particularly suitable for automotive and industrial control applications as well as medical systems.
