hii all,
i am going to interface OLEDM204 lcd with PICf1823 using I2C. i have done all the thing .but now i want to change the contrast and i could not. in datasheet they said that you have to set RE and SD bit
and then only you can do that. i tried it but fail. some one having experience in that cam guide me
Code (Text):
- I2C_Is_Idle();
- I2C1_Start();
- I2C_Is_Idle();
- I2C1_Wr(0x78);
- I2C_Is_Idle();
- I2C1_Wr(0x80);
- I2C_Is_Idle();...
