Hi guys

Can someone explain to me how do we control LCD with a MCU, I mean, there are so many pixels in a LCD, and there are only limited pins in a MCU.

I think there must be a smart way to do it, I just don't know how, can someone point me to the right direction, some terms or concepts that I can google them.

Thanks

 

For text LCD, you should google "How does HD44780 works" or "HD44780 datasheet".

If it is a Graphic LCD you need to google for keyword "KS0108" & its datasheets.

I've used the HD44780 but have not used Graphics LCD's. I assume the KS0108 us a defacto standard controller for these units???

 

Yes the KS0108 is one of the standard controllers for graphic LCDs.

 

thanks guys
