    I just noticed that on the code that I uploaded I had a missmatch on the naming of the Reset pin. In some places it's named RST and in others RES. It doesn't solve the issue, but this code doesn't run like this, so just change the deffinition name to RES.

    Hi,

    Are you using a SPI library to work with the teensy?

    Also, I noticed that your IM settings are incorrect in your 4-Wire case statement for command and data functions:

    case 4:

          digitalWrite(IM0, HIGH);   //IM0 = 1

          digitalWrite(IM1, LOW);    //IM1 = 0

          digitalWrite(DC, LOW);     //D/C = 0
