  • I just made a Arduino code for this display. I enabled serial mode by changing the jumpers on the back. 3-PIN SPI serial mode can be enabled by: * Removing the L_CS_H 0-ohm resistor and placing it on JCS * Moving L_PS_H from PS_H to PS_L

    The datasheet for the RS0010 is really bad and I had a few problems along the way. But the display looks really nice, crisp, clear and fast. It is also dimmable in one step. By disabling the DC-DC converter in software the light output is quite low but nice in low light conditions. I used the datashet from newhaven tp find jumper settings. http://www.newhavendisplay.com/specs/NHD-0216KZW-AY5.pdf And the dataheet from electronic assembly for more detailed reference. It is much better formatted. http://www.lcd-module.de/fileadmin/eng/pdf/doma/olede.pdf

    All these displays are essentially the same.

    The code below is just a crude test that works. Some more testing on clock phase and timing should be done.

    const int SS_pin = 8; // connect to OLED pin 16 const int SCK_pin = 13; // connect to pin OLED 12 const int MISO_pin = 12; // can be connected to OLED 13 (not tested) const int MOSI_pin = 11; // connect to pin OLED 14

    void setup() { //OLED digitalWrite(SCK_pin, HIGH); // SCK high digitalWrite(SS, HIGH); // Start with SS high pinMode(SS_pin, OUTPUT); pinMode(SCK_pin, OUTPUT); pinMode(MISO_pin, INPUT); pinMode(MOSI_pin, OUTPUT); // Init of SERIAL OLED returnValue = bitBang(0,0x39); // Transmit data returnValue = bitBang(0,0x08); // Transmit data returnValue = bitBang(0,0x06); // Transmit data returnValue = bitBang(0,0x17); // Transmit data returnValue = bitBang(0,0x01); // Transmit data returnValue = bitBang(0,0x02); // Transmit data returnValue = bitBang(0,0x0C); // Transmit data }

    byte bitBang(byte control, byte data) // This function is what bitbangs the data { digitalWrite(SCK_pin, HIGH); // SCK high digitalWrite(SS_pin, LOW); // SS low byte _receive = 0; int _send=(control*256)+data;

    for(int i=9; i>= 0; i--) // I want to send 10 bits. The 6 MSB are removed { digitalWrite(MOSI_pin, bitRead(_send, i)); // Set MOSI delayMicroseconds(5); digitalWrite(SCK_pin, LOW); // SCK high bitWrite(_receive, i, digitalRead(MISO_pin)); // Capture MISO digitalWrite(SCK_pin, HIGH); // SCK low delayMicroseconds(5); } digitalWrite(SS_pin, HIGH); // SS high again return _receive; // Return the received data }

No public wish lists :(
