Hello All,
I am new to ARM. I am currently using LPC2378 (ARM7TDMI-S) processor on MCB2300 Keil Eval Board. I want to display A/D value on LCD. Kindly guide how to proceed step by step using C language. I don't have any exposure in Assembly language. However I am considerably good at C.
Regards
what is the meaning of FIOxMASK. In the case of "Blinky" example, there is written a code as follows:
FIO2DIR = 0x000000FF; /* P2.0..7 defined as Outputs */ FIO2MASK = 0x00000000;
What is the purpose of writing FIOxMASK here. What it exactly do?
The purpose is exactly as it is described in the user manual of the processor - to control which I/O pins that will be affected when you make 8-bit, 16-bit or 32-bit assigns to the port. This allows you to set/clear multiple bits with a single assign, without needing to perform a read/modify/write with and/or logic.
I didn't get you. Neither I could get it clear from user manual also.
Did you try to use google translate?
What do you mean?

You can translate Per's post and/or the user manual to your native language.
This has absolutely nothing to do with Keil, and is entirely a matter of the specific chip hardware.
If you need training on NXP products, you should contact your local NXP distributor...
Or, try the NXP forums?
Or, perhaps, get a consultant in to help you:

I beleive that NXP also maintain a Consultants list...
What the user manual very clearly tries to explain is that you can write-protect specific pins on the port.
I want to interface a DC motor on ARM7 board MCB2300 board. kindly guide.
What has that to do with this thread subject - reading A/D values from a potentiometer?
"What has that to do with this thread subject - reading A/D values from a potentiometer?"
Nothing at all!
"kindly guide"
Guidance:
1. Don't hijack unrelated threads.
2. Before You start your own thread, take some time to do some basic research; eg, www.lmgtfy.com
"Don't hijack unrelated threads."
But in this case it wasn't a hijack, but the OP who wanted to switch subject without starting a new thread.
