Replacement: None. It's time for this product to step aside and make room in the catalog for even more cool stuff. This page is for reference only.
Description: This is a development board for the impressively powerful XS1-L1, multi-threaded processor made by XMOS. The XMOS development board includes a XS1-L1-64 processor in a 64LQFP package.
SparkFun's development board for this processor provides an XTAG header for either loading your code onto the external SPI flash or running your code as an XCore application. Thirty two user I/O pins are broken out for your prototyping needs. The board comes with the SPI flash already programmed with some simple example code.
The XS1-L1 is easy to use. The processor can be programmed using the XMOS Design Tools. A design tools supported USB to XTAG converter is needed to load your code onto the XS1. Our development platform can be programmed in the XMOS Development Environment. The SFE development platform can be programmed either by creating a project that uses the XC-5 Development Platform or by using the SFE.xn file found in the example code. Note that the XC-5.xn selects a 20MHz external oscillator. To have all timing I/O be properly scaled, you must change the oscillator frequency in the .xn file to 13MHz.
Note: This revision does away with the UART section of the board, which never really worked in the last revision.
