Custom LCD Chrs & Plugin

[swright]

I've just discovered how to generate custom characters on an alphanumeric LCD display - I'm sure that everybody else discovered this ages ago. All the same, I've attached a small application to generate the print string, as well as a plugin .mcp file (although I'm not sure that I've done this right).

It is possible to generate the characters 0 - 7 in character ram (CGRAM) by sending Print $FE, followed by the number $40 - $78 for the chr start address in CGRAM, followed by eight values to represent the 5 LSB for the 8 rows of each character, e.g. Print $FE,$40,$E4,$EE,$FF,$EE,$EE,$EE,$EE,$E0 for chr(0).

Then to use these characters, simply print 0 to 7, e.g. Print At 1,1, 0

Hi, its great to see you visiting our forum. Why not try Proton Compiler for FREE? Download the FREE version of Proton Compiler, Its called Amicus18 and its available from HERE Already using proton Compiler??? Get rid of these pesky messages... get LICENSED USER STATUS

I hope that the app is self-explanatory. Click to swap pixel state, select chr number, then cut & paste print string into app.

Example code for 8 chrs:

 
Print $FE,$40,$E4,$EE,$FF,$EE,$EE,$EE,$EE,$E0 '$FE,$40 for CGRAM for user chr 0 

Print $FE,$48,$E4,$EE,$F1,$EE,$EE,$EE,$EE,$E0 '$FE,$48 for CGRAM for user chr 1 etc. (8 chrs possible) ($40,$48,$50,$58,$60,$68,$70,$78)

Print $FE,$50,$E4,$EA,$F1,$EA,$EE,$EE,$EE,$E0
 
Print $FE,$58,$EE,$EE,$EE,$EE,$FF,$EE,$E4,$E0
 
Print $FE,$60,$EE,$EE,$EE,$EE,$F1,$EE,$E4,$E0
 
Print $FE,$68,$EE,$EE,$EE,$EA,$F1,$EA,$E4,$E0
 
Print $FE,$70,$E0,$E0,$E0,$E4,$E0,$E4,$E0,$E0
 
Print $FE,$78,$E0,$E2,$E2,$E4,$E4,$E8,$E8,$E0
 
Print At 1,1, 0,1,2,3,4,5,6,7

Steven,

Very nice plugin and very useful....

Would it be possible to add a paste button which would paste the generate print line to the current cursor position in the code.

Also, just out of interest... what language did you write the plugin in?

Thanks. If I can get my head around the DLL calls, yes I'll add a paste button. I had thought of this, but cried shy..! It will do me good to get to grips with it. The app was written in VB6.

Kind regards,

Steven

No DLL calls are required, you need one command to make the IDE the current window and another one to feed the control-V to it:

    AppActivate "Proton IDE"    
    SendKeys "^V"

It doesn't get much easier, once you know how of course. It took quite a bit of research to work out how to do this when I needed to a few years back!
