    it works perfectly when connected to either JA ,JB ,JC, or JD.....the code i used is the example code provided by digilent ....so i want to adapt it to more than one oledrgb on the same board.

  3. Hi everyone, please can anybody help me out on how to use multiple oledrgb on nexys4 ddr board...i'v done my block design and i'v assigned all the pin to the appropriate pmod port that i want to plug them to ....going by the digilent example i'v only been able to write to only one oledrgb on portJA, please is it possible for me to write to multiple oledrgb connected to the nexys4 ddr board.....say for instance 4 oledrgb's connected to JA,JB,JC,and JD..

  8. pmodoledrgb not displaying on nexys4 ddr

    @jpeyron thanks for the response.......please, concerning the font size, i'v written the font in 16x16, now my question is which of the function is used to drive the digilent 8x8 so that i can use that as a guideline for my 16x16 or any other font i like?...........................................i'l be glad if i'm able to accomplish this.
  9. Good day everyone , please how can i program nexys4 ddr so that it can startup with the personal program and not with the manufacturers default code.
