Hi,
I have tried starting a new LPC1114 project and I am finding that commands like LPC_IOCON->PIO1_8 = 0x15; are being ignored, and yet the code excutes and I can drive output pins sucessfully. The hardware does work, with a different project on a different pc. I suspect some configuration issue.

What do people suggest?

Thanks

I would suggest to read Table 59. What function do you expect with setting bit 0 and bit 2 :confused:

Also I would suggest to use debugger to read the result of your IOCON settings :)

Hi,

Thanks for the hint I have changed it to LPC_IOCON->PIO1_8 = 0x21; however in the debugger it is staying as PIO1_8 and not changing to CT16B1_CAP0. When I try to force it to CT16B1_CAP0 it changes back to PIO1_8 and states it is reading all 0.

After writing 0x21 to LPC_IOCON->PIO1_8 my debugger shows:

LPC_IOCON->PIO1_8: 0x21
HYS: HYSTERESISON
MODE: INACTIVE
FUNC: CT16B1_CAP0

If that's not working you're changing this register somewhere else :mad:

Even when single stepping I am getting this issue.

Are we talking about LPC1114/301 with LPCXpresso 3.6.2 ?

Which LPC_IOCON->PIO1_8 value does your debugger show before and after LPC_IOCON->PIO1_8 = 0x21 ?

Hi,

It is the LPC1114/302 LPCXpresso:
Version: LPCXpresso v3.6.3 [Build 317] [08/04/2011]

Before and after LPC_IOCON->PIO1_8 = 0x21
IOCON_PIO1_8 is still reporting HYSTERESISOFF INACTIVE PIO1_8

That's 0xd0 = default value and doesn't change after write?

My 3.6.3 with LPC1114/302 is working without problems.

I am suspecting there is some strange project issue, it works fine with other projects.
