Hi guys,

I would like to ask you,, if there is some issue with pin PIO0_1 on LPC812. I've tried to use this pin as output, but this pin is all the time in the same voltage level in 1,6V. I have chip version with ISP on pin PIO0_12.

I use LPCopen.

1) Disable fixed pin function

  
 Chip_SWM_Init();
    Chip_SWM_DisableFixedPin(SWM_FIXED_ACMP_I2);   // I've tried to disable only one fixed function without any results
    Chip_SWM_DisableFixedPin(SWM_FIXED_CLKIN);
    Chip_SWM_Deinit();


2) Init GPIO

 
  Chip_GPIO_Init(LPC_GPIO_PORT);


3) Set direction

  
Chip_GPIO_SetPinDIROutput(LPC_GPIO_PORT, 0, 1);


4) Set state

   
Chip_GPIO_SetPinState(LPC_GPIO_PORT, 0, 1, 1);


Any ideas?
Thanks :)
