Hello ,I'm confused
how do I read data previously written to the internal flash memory of the
LPC2148?
I read somewhere that I have to use pointers, but I did not understand how
to use pointers to read data from FLASH.
can anyone help me?
thanks

I'm afraid, this is completely off topic but anyway for example at the
very end of this:

I am not writing the code for you, coz this is basic C. Declare a pointer
and assign it the flash address you want to read. Thats it.

Hello everybody, thanks for the tip.
I am newbie in c programming language, then I apologize for the email.
I will not let you down again (I hope hehehe ), the next step will be to
communicate with PC using USB,and set the RTC to act as an alarm.
Nishant Agrawal and Timo , thanks for the help

Then you REALLY want to see JC Wren's demo code: www.jcwren.com/arm
JC has done all the heavy lifting in terms of getting USB working with a PC. The code is for the 2148 but it should be close enough.

In fact I will use the USB as a virtual communication.
I'm reading AN10420 (NXP) and files VirtualCOM.zip (LPC2000 Group).
I have a long road ahead.
I'm using KEIL uVISION4 compiler and simulating LPC2138 component in
PROTEUS.
Can anyone tell me if there is a component to simulate the LPC2148 for USB
support on PROTEUS ?
Thanks,
Claudionor.
