Question about 256x64 sample code
« on: November 16, 2016, 08:28:22 AM »
In the provided code snippet , there are some parts that neither my compiler nor i, can understand .

Link to the code :

  case 1:

Ascii_1 array was never defined, should i create a global ascii table array in order to make this function work ?


  • Again, shift was never defined.

Both of these lines are in void Show_Font57_25664() function. I am trying to port this code to a pic MCU . How can i find the missing variables ?

Some of these commands are required for our NHDev Development Board code.

I do have example Arduino code for this display, could you please email me at for the examples.
