Title: CM8870 DTMF decoder routine using EBL library
Post by: dakudiv on Jun 13, 2012, 12:07 pm
Hi,
Here is the code for working with CM8870 DTMF library.

I posted another routine for decoding DTMF from MT8880 Transceiver some days back at http://arduino.cc/forum/index.php/board,22.0.html  (http://arduino.cc/forum/index.php/board,22.0.html).

For hardware simply refer to Figure 1. in of the CM8870 IC datasheet.
