Dear all,
I am using Keil MDK 4.12, and MCB1700 board.
I managed to port simple program examples from MCB2300 to MCB1700, but when I try to port more complex program (RL-TCPNet) I found problems with compiling.
Kindly help me to point me to help file or website that have similar sample case, I have search the forum and knowledge base, but no result.
Thank you in advance for your kind help and attention

Problems with compiling are to do with your 'C' language syntax & usage - not to do with the differences between MCB2300 & MCB1700.
Dealing with compiler errors is a standard part of the programming process in any language on any platform - nothing specifically to do with embedded, Keil, NXP, etc...
What errors, exactly, are you getting?
Usually, compiler errors tell you exactly what is wrong - and, from that, it should be easy to fix the problem!
The key is to read the messages literally; eg, if the message tells you that something is undefined - then the solution is to define it!
Note that one error often leads to a load of consequent errors - so fix the first error first!
Project: adc.uvproj (from sample code) Tools: Keil 4 Previously it compile without error, test it on MCB1700 and works fine.
Later I add simple instruction:
FIODIR2 = 0x000000FF; FIOMASK2 = 0x00000000; FIO2PIN = 0x00000000; PINSEL10 = 0;
The compiling msgs are below: I try to update the lpc17xx.h file as suggested by John L, but still the problem exists. I also try to define path in each file option and directory option to point to where the dependencies located.
Please help...

I check in lpc17xx.h, it does contain the undefined parameters.
Sample of lpc17xx.h is below

You have incorrect usage.
You use FIODIR2 - probably assuming it controls the direction for port 2.
But note in the header file. FIODIR2 is a field in a union, inside a structure named LPC_GPIO_TypeDef.
You need to look up the variable of type LPC_GPIO_TypeDef that relates to the port you want to control. Then you need to access the relevant fields for that variable.
And FIODIR0, FIODIR1, FIODIR2, FIODIR3 are there if you want to just perform an 8-bit operation to update the port direction for a group of 8 I/O pins of a port.
You seem to want to perform an assign of a 32-bit value - this would correspond with the union field <port-variable_name>.FIODIR. Or you only want to change the low byte, in which case you should use <port-variable_name>.FIODIR0.
If the variable is instead a pointer, you have to use <port-variable_name>->FIODIR.
Mark thank you for the information, the problem is solved now,thanks to your direction and also other friends info.
Again thank you for everyones help Hopefully I can also help anytime soon
