Hi,
I could be able to purchase a number of second hand intelligent
barcode scanners. I have project in mind where I could use such
devices.
The scanners run Windows CE 5. Is it possible and advisable to
develop for these devices using Lazarus ?
I know Lazarus has support for Windows CE, but at the moment I
don't find which versions are supported.
Lazarus (LCL) supports WinCE. I use it for Windows Mobile 6.5.
To what extent does the choice of CPU matter?
In what sense?
Sven mentions x86. I see Loongson (MIPS-compatible) runs it. There was
ARM, obviously, and I think there was some other obscure architecture.
In the case of ARM, and I'm particularly thinking about Linux on the
Raspberry Pi here, there's different subarchitectures.
Arm has different sub architectures indeed. Lazarus has a selection
dropdown list that lists a few of them. But IIRC, WinCE is limited to
ARMv4 or below.
Wrong. Windows CE also runs on more modern ARM processors. It's the
core of Windows Phone 7 after all.
I recall reading somewhere on the Lazarus/FPC lists or forum that the
arm subarchitecture should be set to v4 for WinCE. Could it be a
limitation for the emulator?
So I think there's a real possibility that there's CE-compatible
boards which could give FPC problems. I'd be happy to be told that's
wrong.
In general:
- FPC should be able to compile for the target CPU.
- WinCE should run on the target.
- Now you can worry if Lazarus WinCE programs could give problems on
that target.
The order should be:
- WinCE should run on the target
- FPC should be able to compile for WinCE on that target
- worry about LCL
My emphasis was on the 3rd point, but you are right in switching the
first two.
Regards,
Stephano
