Example test code:
| const int CS = 10; //CS pin to Arduino pin 10 const int INC = 9; //INC pin to Arduino pin 9 const int UD = 8; //UD pin to Arduino pin 8 void setup() { pinMode(CS, OUTPUT); pinMode(INC, OUTPUT); pinMode(UD, OUTPUT); digitalWrite(CS, HIGH); digitalWrite(INC, HIGH); digitalWrite(UD, HIGH); } void loop() { for (int i=0; i<=100; i+=10) { setResistance(i); delay(100); } } void setResistance(int percent) { digitalWrite(UD, LOW); digitalWrite(CS, LOW); for (int i=0; i<100; i++) { digitalWrite(INC, LOW); delayMicroseconds(1); digitalWrite(INC, HIGH); delayMicroseconds(1); } digitalWrite(UD, HIGH); for (int i=0; i digitalWrite(INC, LOW); delayMicroseconds(1); digitalWrite(INC, HIGH); delayMicroseconds(1); } digitalWrite(CS, HIGH); } |

Achzitionat acest potentiometru digital prin intermediul firmei la care lucrez si dar din pacate se coporta diferit fata de specificatii chipui X9C103S: - alimetat VH la +3.3V si VL la GND si rezolutia este de 100mV si nu cum scrie in specificatile pt X9C103S si in consecinta am doar 33 pasi in loc de 100 ( 3.3V / 100 = 33mV per puls) - alimetat VH la +5V si VL la GND si rezolutia este de 150mV - verificat pinii si toate alimentarile - codul incercat din mai multe surse pe pe internet (acelasi comportament) si in loc de UP face DOWN si vice versa si rezolutia este de 3 ori mai slaba (in loc de 100 pulsuri sunt doar 33). Concluzia: nu cred ca este acelasi chip X9C103S pe aceasta placa - m-am uitat cu lupa si este ars cu laserul partea superioara, pt nu putea identifica chiupul :-)
