MPR031 HELP!!!

rfslf — Fri, 14 May 2010 23:19:31 GMT

Please help me!
I use MPR031, and I can not start-up.

When I send 0x4A address, line is tied to ground and I cannot send command address.
When I send address from all range of possible, MPR031 does not respond.
MPR031 soldered well, contact is good. There is no answer from MPR031.

Please help me examples of an initial configuration of registers for MPR031.

Best regards,
Alex

Did it work? I have the same problem. But it responds the adress but gets all zeros from EVERY register. Even if i write before i read.

Which is not the same problem. The original poster couldn't get a response at all.

Have you read the other posts in this forum on the MPR031 (and MPR121)?

Type "MPR031" into the Search Box and read the previous articles.
