Hi folks,
has anyone been working with a Motormind C chip & managed to change the PWM frequency? The default frequency of about 1Khz is fairly earsplitting hence I'm trying to change it to the alternative 19Khz.
The datasheet says to send D4, 01, 00, D5 (all in hexadecimal). I've sent this and the LED has flashed for data present onthe Motormind C yet, when switching back to Analog mode, which is the mode I'm using, the PWM speed seem to be unchanged (same earsplitting sound).
My code contains:
byte value1;
byte value2;
byte value3;
byte value4;
etc....
value1=212;
value2=1;
value3=0;
value4=213;
Serial.print(value1);
Serial.print(value2);
Serial.print(value3);
Serial.print(value4);
any ideas?
Nic
