How Would I Start Programming LPC Using C

Every GPIO pin has a minimum of one function and max of four functions. As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function.

By this, the first 16 P0. The remaining 16 bits P0. As mentioned earlier every pin has a max of four functions. This register individually controls the direction of each port pin.

Port Output Set Register. This register controls the state of output pins. Writing 1s produces highs at the corresponding port pins. Writing 0s has no effect. Reading this register returns the current contents of the port output register, not the physical port value.

Port Output Clear Register. Writing 1s produces lows at the corresponding port pins.

Writing to this register places corresponding values in all bits of the particular PORT pins. The current state of digital port pins can be read from this register, regardless of pin direction or alternate function selection as long as pins are not configured as an input to ADC.

It is recommended to configure the PORT direction and pin function before using it. Program to demonstrate the LED blinking. For that you need to include the gpio.

The below sample code shows how to use the GPIO functions. Download the complete project folder from this link.
