I am going to using the uart to control the led,if i using the uart in the computer to send the 01 05 00 02 FF 00 2D FA,then the led on the p-2-10 will be lighten.if i send the 01 05 00 02 00 00 6C 0A ,the led will be not dark.Can you help
me.. thanks.

Hello wzq121381,

this will be difficult, because we know almost nothing about your environment.
We don't know your protocol, uC, software you are using.
Check if you can control your led without UART, just by setting your GPIO in main (e.g. in a while loop).
Check if P2.10 is a special pin, which perhaps needs a pull-up/pull-down (open collector pin).

Best regards,

Martin

I am using the rs232,and the p2.10 can be lighten by GPIOSetValue(2,10,1);but I need to control it by uart ,just if the uart send something ,then the led will be control.

Without giving us more input (e.g. source code and perhaps protocol description), we are not able to see if and where there is a bug, sorry.

Hi,

That Just
1. receive uart data.
2. parser the uart data command.
3. let LED on/off.

You can get the LPCxx sample code to modify it.

can you write the code? I know
1. receive uart data.
2. parser the uart data command.
3. let LED on/off.
but i do not konw how to write the code
thanks

Do you pay for writing the code?

Seems there is already some code available. Thread continues here:
