Hi, my name is Christian. I have folling problem. I want to read 15 bit digital data from an external sensor board. The external board produces folling signals - 15 Bit digital Data (Image Sensor) - FEN, Frame enable signal - LEN, Line enable signal - CLK a clock with 1,23 Mhz. Can anyone tell me how I can read the 15 bit data into the internal memory. The HPI can be used a 8/16 bit Port. Can I use the 16bit HPI to read the data. But I dont't have an adress. I must control the read operation with interupts from the control signals (LEN, FEN, VLK). I've read about the 16 memory mapped I/O Port of the C5409 but I don't understand where the port is located on the DSP. If anyone has a suggestion how this can be done please mail me to Thanks Christian |
