Hi Graham,

This is probably too simplistic, but you can toggle the output with
a sleep(t) between to make a square f=1/(2t).

Q Is there a way to produce a audio frequency clock . from gpio pin - 4 ?
Dividing the main clock , would appear to be limited to app 32KHz 

is there  another  way  to  produce  lower  / audio  frequency's  ?

Tnx -G,
