So when writing code for linux, you can write is user space (where most code runs) or from kernel space. Interrupts are purely in the domain of kernel space. The UART drivers are all fully interrupt driven. Here is some sample code for reading/writing to the serial ports: https://github.com/dhylands/projects/tree/master/host/sertest Here is some documentation on working with serial ports under linux: http://tldp.org/HOWTO/Serial-Programming-HOWTO/ -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
