' This demo program is a rudimentary memory dialer. Since DTMF digits fit
|
|
' within a nibble (four bits), the program below packs two DTMF digits into
|
|
' each byte of three EEPROM data tables. The end of a phone number is marked
|
|
' by the nibble $F, since this is not a valid phone-dialing digit.
|
|
' Conditional compilation sets the timing adjustment factor so that the
|
|
' output will sound the same on any BS2 module.
