LPC3250 Developer's Kit

 

 

The LPC3250 Developer's Kit is a ready to use platform that will let you explore the many features of the LPC32xx microcontroller series in general and the LPC3250 in particular.

 

The Kit is perfect for running Linux with its large on-board RAM and Flash, network and graphics capabilities.

 

Focus on your value-added application by using this Developer's Kit as your prototyping platform. It includes the software components needed to get up-and-running with your software development on day 1.

 

When you are finished with prototyping and/or evaluation you can easily transfer your application and the OEM Board into production.

 

Low Cost

The LPC3250 OEM Board is very low cost and can be used for prototyping/development as well as for OEM production.

ADC - an example using interrupts to measure ADC channels 0, 1 and 2 Ethernet - A polled Ping application that illustrates the usage of the Ethernet interface Kickstart - A simple bootloader stored in block 0 of the NAND flash loading an application stored in block 1 an onwards. LCD - An application using NXP's SWIM library to draw some color bars on the QVGA LCD display NAND Programmer - This application programs the NAND flash with the kickstart application in block 0 and a second application, for example, the S1L application in block 1 and onwards. RTC An example using the Real-Time Clock to generate TICK events S1L - A more complex bootloader that allows you to load applications from several sources such as the NAND flash, serial port or MMC/SD card.

SD/MMC - A sample application using the memory card interface SLC NAND - An application that is using the Single-Level NAND controller to read and write data to the NAND flash. SPI NOR - This application illustrates how to read and write data to the NOR Flash. Timer - A simple example using the timer interface Touch Screen - This application first runs a calibration sequence and then uses NXP's SWIM library to let you draw on the display using the touch screen. UART - A simple example illustrating how to use the UART
