Character LCDs / Re: Problems with a NHD‐0420H1Z‐FL‐GBW‐3V3

Hi...i am a new user here. As per my knowledge the difference between them is that they are using different parameter values.  The controller knows its the function set command based off the first nibble "001x" (x = dont care).  That last dont care bit, along with the second nibble, are the parameters for the command.  The first 0x30 call is to "wake up" the display as you have said, the 0x38 call is to configure it correctly.
