Positioning Texts

[Nathan]

Hello,
I'm trying to develop my ARM OS, but I need to know how could I position text on the screen. The only information that I hate at the time, is the address that I got from the Integrator/CP Reference Manual, that is 0x16000030, but I don1t know what to do with the value. Someone could help me with this?

Best Regards,
Nathan Paulino Campos

No colours.

It's a serial port, not a display. There is no position.

Find out what's interpreting the data coming out, and seek out the reference for that.

I haven't found anything like that in the reference.

Just look at the board. What is connected to the port? Is it the display? If so, are there any markings on it that tell what kind of display it is?

[Nathan]

I don't have the board, I just emulate it using Qemu.

I don't have the board, I just emulate it using Qemu.

Check the QEMU docs (although the documentation seems to be awful for non-x86 system emulation..) or the source (this will have the answer)

EDIT: From reading the QEMU documentation and looking through hw/integrator.c in the qemu source tree because I really didn't have anything better
to do at the moment, it looks like there's a PL110 LCD controller at address 0xC0000000. You can find the offsets from looking through hw/pl110.c, or
ARM has the PL110 datasheet on their infocenter. Research is a good idea.

I will take a look at that.

I've understood it, but still don't know what syntax should I use to make work. Someone can help me?

No. Ask a smart question first. You just failed about all the rules on those.

[JackScott]

Try the syntax you think should work, and see what errors you get. If you have honestly no idea where to even start with the syntax, go back to step 1 and learn C.

[Nathan]

I don't even know what syntax to use, because I don't have the necessary information to think on it.

[JackScott]

Then either learn C, or GTFO. It's your choice.

Still don't know how to kill bugs?
