Help me Bit Bang a little I2C for my ProMicro

Other Hardware Displays

Bill,

I am doing pretty good with your suggested code but in implementing it with other code I have written, I have a couple of issues.

Do I reallyt need:

{
int istatus;

  istatus = lcd.begin(16,2);
  if(istatus)
  {
 // LCD initalization failed.
 // handle it anyway you want
 if(istatus < 0)
 istatus = -istatus;
 lcd.fatalError(istatus); // blinks error if LED_BUILTIN is defined
  }

The ProMicro doesn't really have easy access to an onboard LED. They are so bright anyway that I have them turned off in the beginning of my code. I have plenty of blinkies on my PCB

I was just going to replace it all with "lcd.begin(16,2)" but thought I would see why you suggested I use these few lines before jumping ahead.

I have another question but thought I should keep the dialog brief.
