I am new to this microcontroller;actually to microcontrollers in general.I am a student.I need help for my final yr project.How do I interface philips lpc2148 with my battery charger circuit?can anyone help me?
For some thing that simple, you are better of using 8052 as opposed to ARM based processor.
Like the old saying "you have to learn how to walk first before you can run"
"For some thing that simple"
How do you know the application is simple?
The only thing that's been mentioned is some unspecified sort of "interfacing" to some unspecified sort of "battery charger"
We have no idea what sort of interface it is (or needs to be), what sort of data is to be transferred via this "interface", what processing may be required, whether this forms a major part of the project or, indeed, anything much at all!
A bit early to declare that it's "simple", methinks?
Well, there are a lot of battery charger chips made by maxim (maxin-ic.com). Most of their chips have a basic simple interface to CPU via SPI, I2C and such. I don't see any compelling reason why you would need an ARM processor for that. There are also several apt notes available on the website that you can download.
Now, If you are saying that a 8052 CPU can't do it then you must be building something very special !!
