Post by thread:Code for Serial Interface Adapter for TC500 a/d

Hi, I've been given a project that requires a PIC to talk to a tc520a serial interface adapter. Before I spend countless hours trying to figure out how the whole thing works, I thought I'd check to see if anyone on the list has already done so. If you've got code, or any other advice that you can share I'd be eternally greatful :) .scn

What is a tc520a SIA?

Page 2-189: TC520a General Description The TC520 Serial Interface Controller provides complete logic control for the TC500 or TC500A Analog Processors in a compact 14 or 16 pin package... From Page 2-179 TC500 General Description The CMOS TC500/TC500A contain all the analog circuits needed to construct an integrating analog-to-digital converter. The user can control resolution and conversion speed through software. A uP controls the TC500 through the A and B logic input signals. ------ So, now after reading this, I'm wondering why we ned the TC520 at all. I would imagine I could do it all with PIC software... Has anyone used the TC500 a/d with a pic, and if so how complex/simple is the process? .scn

Thanks Shane, I was just curious. I would agree that the serial support chip is not needed unless your customer requires it. I can't imagin that the interface is very complex, after all it's just another A/D converter. Sounds like you already have the book, time to do a little light reading :-) Mark So, now after reading this, I'm wondering why we ned the TC520 at all.
