Lpc2000

Anyone generating IR with the LPC2000?  Wondering if there are any
pins that would be better to use than plain ole GPIO (i.e. MAT or PWM
for instance).

Thanks,

Gary

Use a match output pin in conjunction with the timer peripheral.  The timer 
peripheral suits generating and receiving consumer IR sequences exceedingly 
well.

My question is regarding good habbits of manipuating IO's.
In the freertos environment I'm toggling output bits as
(relevant code marked with ***)

while(....){
*** IO0CLR = ADDRESS_BUS;                              // Put address on bus
   IO0SET = addr << ADDRESS_OFFSET;

   IO0CLR = IOR;                                   // IOR-signal low
   value = (IO0PIN >> DATA_OFFSET) & 0xFF;    // get low order byte from 
data bus
   IO0SET = IOR;

***  IO0SET = 1 << ADDRESS_OFFSET;
............................
}
During debugging I see proper CLR intr. execution at the begin of while(){}.
But somewhere in the middle first SET instruction is presuming the bits 
are cleared.
But when watching IO register status there seems the bits are no longer 
cleared.
Does it has sth to do with debugging, or RTOS ( which in fact doesn't 
play with bits at all anywhere else)?
