Your English is fine, much better than my Spanish.

I think you are correct, the more ram the better.

I also agree on dividing the code into smaller projects for testing. That seems to be the trouble with some, they try to write the whole code at once an then wonder why it does not work. Much easier to debug smaller codes than larger ones.

Have you tried the CTS to control the data from the VDIP? IF so, how is it working?
