pls help mw with my project

[sandy_m2k2]

hi friends.

i have to build a intelligent battery charger.i have identified the circuit i want to use but unfortunatly i have to replace the microcontroller with philips lpc2148 microcontroller.so can anyone help me with this?

i am enclosing the schematics of the development board for the philips lpc 2148 as well as the battery cahrger application notes..the circuit is on page 8..
pls help me by teaching me how to replace the microcontroller here..
this is urgent and i value any help..
thanks in advance,

sandhya

i'm not able to attach the i.5mb pdf file with the circuit wat can i do?

hi sandy,
Some members are finding its not possible attach pdf,s.

I find, if I keep the pdf size less than about 30kbyte, it will attach, bigger than that you get a white/blank dialog box.

Look at the upload dialog box and see what alternate format you can upload.

Just be patient and wait for it to upload I've often found that it can take awhile to upload things. I don't know whether it's the server on this site being slow or my upload bandwidth is a lot less than my download bandwidth.

I'll admit to being a bit confused as to why you need the intelligence. Indeed why if one were to insist on a micro why you would go all the way to an LPC2148...

I have experience with the LPCs as well as battery chargers. Feel free to IM me as I have experienced hostility in these forums when ARMs are suggested as viable.

Maybe the OP is really wanting to build a battery conditioner/analyzer like a Cadex and wants to log the data to his PC via USB.
But you're right that a micro is usually overkill because you can get dedicated charger chips for most battery types now.
