We have added two new libraries for Windows CE in support of our Colibri PXA and T20 Computer on Module families.
SPIDMALib provides for communication through the on-chip SPI interfaces at speeds of up to 26Mhz for the PXA and up to 54Mhz for the T20 with DMA support for bi-directional data transfer. The API for this library can be found here: http://developer.toradex.com/knowledge-base/spi-with-dma-library-api.
CAN-MCP2515Lib provides for communication to the MCP2515 stand-alone CAN Controller at up to 10Mhz via SPI. The MCP2515 provides for up to 1Mb/s CAN V2.0B communication with two receive buffers with prioritised message storage, six 29-bit filters, two 29-bit masks, and three transmit buffers. The API for this library can be found here: http://developer.toradex.com/knowledge-base/can-mcp2515-lib-api.
