Most efficient LCD driver?

LCD Debug is a gross offender. I use bin, decf, hex, str, and that's about it. Anyone know what is the most efficient method to drive an LCD for these few requirements? I have a spare port on the 4x driver, configuring that port as an LCD driver would be ideal if there is a way to make use of the same functionality of the above needs without adding cogs. Thoughts welcome.

    I just noticed that Tim has already conveniently prepared the 4port with sufficient LCD capabilities to not really need the Debug LC any longer.

    TChapman,

    LCD Debug is a serial LCD driver or graphics LCD driver?

    I am working on a driver for an LCD that I will be selling soon. The display is a graphics display though and not a serial display. The LCD driver I am working on will work with graphics.spin so just about any graphics can be drawn on the screen.

    If LCD Debug is a serial LCD driver, then maybe you can just narrow down and remove what you don't need.

    Try this one. Only spin and no extra cog required.
    It's a modified version of the one in the obex from Simon Ampleman modified to have busy polling and initialise reliably.

    I have a nice solution using the spare port on the 4 port so that no new cogs are required.

    Yeah, I forgot I can't attach .spin files without renaming them <grumble>

    As long as the method isn't used (directly or indirectly), you can always edit it out of the object.
