hi, thank you to mr Brett Hagman of Rogue Robotics
for the library and the explanation,
I have put togher this code, to generate 1Hz, 10 Hz, and 50Hz as test,
the freq2 is the timer of 16 bits
" The timers are allocated sequentially when you declare the Tone objects. The second timer is Timer 1, which is a 16 bit timer."
Ok, very nice, thank you again Brett for the library and the explanation,
now to do my project !!! hahaha
