Once I have everything worked out, then I’ll look at going to a cheaper LCD screen.

That way I can easily change how I want the display to work. Second, the project I’ve been working on is going to need to use an Adafruit Touchscreen to manipulate controls during the early development phase. I’d really like to be able to cross compile on the same new version of the Lazarus compiler. It is a lot faster, but still nowhere near as fast as my PC.

See update at end of post.Īdvance forward a couple of years, and I’m looking at building a cross compiler again for two reasons.įirst, I just got a recent version of Lazarus running on my Raspberry Pi Model 2 and I was hoping it was fast enough it would become my development platform. Update: Turns out this bug has not been fixed which limits the usefulness of cross comping. I wasn’t planning to write any GUI apps at that time, so I wasn’t too worried about it. I managed to do it, but there was an issue with writing GUI based apps (I can’t recall exactly what was failing now). (The files uGreen.pas and uBlue.pas are very similar to uRed.pas and the forms uGreen.lfm and uBlue.lfm are very similar to uRed.lfm).When the Raspberry Pi first came out, I spent several days trying to figure out how to build a cross compiler. URed.lfm object frmRed : TfrmRed Left = 795 Height = 240 Top = 270 Width = 320 Caption = 'Red Form' ClientHeight = 240 ClientWidth = 320 Color = clRed LCLVersion = '0.9.30' object btnMenu : TButton Left = 16 Height = 25 Top = 16 Width = 75 Caption = 'Menu' OnClick = btnMenuClick TabOrder = 0 end end

btnMenuClick ( Sender : TObject ) begin hide frmMenu. UMenu.pas unit uMenu interface uses Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls type TfrmMenu = class ( TForm ) btnRed : TButton btnGreen : TButton btnBlue : TButton procedure btnBlueClick ( Sender : TObject ) procedure btnGreenClick ( Sender : TObject ) procedure btnRedClick ( Sender : TObject ) end var frmMenu : TfrmMenu implementation uses uMenu procedure TfrmRed. CreateForm ( TfrmBlue, frmBlue ) Application. CreateForm ( TfrmGreen, frmGreen ) Application. CreateForm ( TfrmRed, frmRed ) Application. CreateForm ( TfrmMenu, frmMenu ) Application. Project file MenuDemo.lpr program MenuDemo uses Interfaces, Forms, uMenu, uRed, uGreen, uBlue begin Application. We show below the contents of MenuDemo.lpr, uMenu.pas, uMenu.lfm, uRed.pas and uRed.lfm.
