    Hey guys,
    Im new to embedded systems design and just need soe direction on what to do.

    What i wanna do is connect and interface sensors to the nios II microprocessor. These sensors include ; temperature sensor, hygrometer , rain gauge , solar radiation , humidity and wind spped/direction (anonemeter) .. These sensors then produce data to be sent to a remote PC

    What i know so far is lets say a TM temperature sensor producing an Analog V signal , which in turn will have to provide input to an AC converter. The ACcon then provides an input for the FPGA.

    What i'm not getting a hang of is how to interface the sensors with the microprocessor and the technique , the use of interrupts an DMA , data memory storage , reading and writing, and its communication to the PC for user interface. SO basically collecting the data and sending it to a PC and software in C on how to do this is the next step.

    Can anyone help me out in detail so i can see the big picture? really am lost in this and definitely need help in detail. Any help would be appreciated

    regards
    M
