Of course its kind off obsolete tech we are talking here … the SAA1064. But then that is the one which packs so much punch / easy to use / HV capability and more than anything I have many to spare !!
I have driven it successfully with 2.3" CA display following a tip in of the recent threads.
But now my requirement is to drive 3 sets of displays and with different Vf voltages for each set of displays. I have made a sketch… just wanted to know what could be the size of the pull up resistors when I am driving this with a MCU which has no in built pull up and runs off 3.3V.
just wanted to make sure before going for the PCB…
