Hello,
I have the TSW4100EVM working nicely now - thanks to help from forum.
I want to design a digital filter that can be controlled via a pic.
I already have designed an analog filter controlled by a pic that downconverts from UMTS to lets say 100MHz. I can control this frequency with the pic. The pic is accessed via a webpage GUI over ethernet. The downconverter had a GUI program that you can set up and it then loads the data into registers on the chip. SimiIer to the TSW4100. I made a program in C on the pic that shunted the correct data into the downconverter to give you the desired frequency.
I would like to now add a DSP filter to allow the user to control the B/W of this 100MHz signal. Down the road I'd like to add multiple band options and so I thought the TSW4100 would cover this too. Since I have the pic, can I use it to program the FPGA? Is this the correct or best way to proceed?
In other other words, how can i get my pic to do the job the existing TSW4100EVM GUI is doing? Or at least load the tap files and set up the DAC.
How do I program the FPGA registers using a pic?
