Part Number:PGA309
Dear All,
I've tested the PGA309 with the evaluation board programming it by TI software.
Now I'm trying to do the next step: communicating directly in ONE WIRE Protocolol using a RS232 to ONE WIRE converter (DS9097U which has inside teh DS2480B) and sending commands directly by a simple serial software.
My problem now is that PGA 309 never answers my commands.
I'm sending:
SET REGISTER ADDRESS POINTER 0x55 0x01 0x01 followed by
READ REGISTER 0x55 0x10
as descripted in figure 4-6 of the PGA309 User's Guide .
Now my questions are:
-Is it possible that my 232 - ONE WIRE converter has a different standard wrt PGA309? I don't think so but since nothing is working it becomes a doubt.
-Are the commands correct? Is there an example of serial commands or other utilities?
Best Regards,
Mattia
