Introduction¶

This page is an attempt to summarise and link to the various LCDPANEL drivers available for the various MMBasic platforms.
These can be built in (OPTION LCDPANEL xxxx), Cfunction loadable drivers or MMBasic drivers implemented with the OPTION LCDPANEL USER method.
The scope includes links to various TBS threads that discuss supporting PCB designs, drivers etc, where to purchase.
In general this page will try to link to relevant threads on TBS rather than reproduce the information here.

This page initially inspired by @panky's TBS post.

Support for BLIT, transparent text and PIXEL() function¶

Many drivers now allow the support for the BLIT command, transparent text and the PIXEL() function to read the colour of a particular pixel.
Transparent text is invoked by using a background colour of -1 and the BLIT command allows the background image to be saved and then restored allowing moving objects to be displayed over a background image. See the section Basic Drawing Features in the updated Micromite Plus Manual .
Two approaches are used to achieve these features.
1. The memory of the LCD PANEL is read by MMBasic to determine what is currently displayed.
To use this the RD pin needs to be connected and the LCDPANEL support the reading of data.(RD required) in table below

2. MMBasic keeps an image of what is currently displayed in its own memory and only every does Write actions toward the LCD PANEL.
This allows these features to be implemented when LCDPANEL doesn't support reading of data. RD pin is not required.
This uses memory from MMBasic and is usually only supported for the smaller resolution displays and when the MM is use has sufficient memory. (BUFF used to indicated this in the table below)
