I am using the LPC4088 development board and my primary goal is to configure a certain GPIO pin as an analog input. In theory, I understand what bits need to be changed in order to achieve this, but I am finding it difficult to actually program this in the LPCXpresso environment.
Specifically I want to configure IOCON_P0_24 (0x4002 C060) to act as an analog input. My plan to do this was to define the register and then use the |= operator to change the value, for example:
...
#define IOCON_P0_24 0x4002C060
...
IOCON_P0_24 |= (0x1 << 0);
...
I am getting an error that is saying "lvalue required as left operant of assignment". This leads me to believe that I need to define IOCON_P0_24 differently or include it from somewhere else.
Could anyone suggest what the best way to adjust the register value? Any help is very much appreciated!
