Hi, Very newbie problem. Sorry for that. IO0SET = 0x00000100; /* Turn LED Off (P0.8 = 1) */ I didn't get the 0x00000100 in datasheet. What does it mean? How would I understand other pin configerations as well? Please tell this newbie in details. Thanks in advance.

0x00000100 represents 8 4-bit hex digits, 32 bits in all. The right two digits represent the bits 0..7 so the 1 in the next digit is bit 8 of 32 and it would set P0.8 to a 1. To clear P0.8 do: IO0CLR = 0x00000100; --- In lpc2000@yahoogroups.com, "mahbub1833" <fireball003@g...> wrote: > > Hi, > Very newbie problem.

Thank you very much! That means if I want to enable p0.9 then i would write 0x00000200 (0x0000 0000 0000 0000 0000 0010 0000 0000)...Am I right?? Then what for p1.25 or p3.4 or other pins? How would I initialize those pins in this way? Would you please send me a link where it is already explained? Thank you. --- In lpc2000@yahoogroups.com, "rtstofer" <rstofer@p...> wrote:

Yesterday I got my XMas Tree. And I must really confess I like it. Also till now I routed "eval" boards myself. I am not willing to spend f.e. 1k $ for a LPC 3000 board. This is simply crazy. I would be really interested what kind of bells & whistles they added to justify this kind of price. On the other hand companies like emb. artists let me reconsider my strategy. I think I will soon buy a "real" board from them. The price is really fair and the boards are interesting. So thanks and Merry Xmas Michael

I could not find anything special on the board but I understood from a
collegue that these kind of boards are expensive to create.
Remember, the LPC3000 is a BGA device.

You will defenitely love the boards. I've got the 2106, 2138 and 2148
boards, with prototype boards (for these prices I cannot even create a
breadboard solution).
The current prototype board needs extra 'spacers' between board and
module, otherwise the DB9 connector on the lpc21xx module in in the way.
I did not like this way of mounting so I removed the DB9 connector from
the lpc module and placed the second connector on the prototype board.
Two wires route the Rx/Tx signals to the module, the generation of the
Reset and P0.14 signals using RTS/DTR is already on the board.
Look at http://www.myvoice.nl/electronics/ for a small description and
some photo's
I just received their newest design: a prototype of the education board.
This is a nice board for students or as hands on board for a programming
workshop.
Merry XMas,
