This register individually controls the direction of each port pin. Program to demonstrate the LED blinking. Port Output Set Register. Port Output Clear Register. Pins of each port are labelled as PX. As mentioned earlier every pin has a max of four functions.

PIC Programming – what to start with? Download the complete project folder from this link. I apologize for f kiddy questions in the professional forum. SPI Module of Arduino.

Blink LEDs connected on pins P1. Port 0 has 32 pins P0. This huge amount of memory is well suited for almost all the ptogramming. How is the datasheet helpful to me? We have given the most basic option for you. This register controls the state of output pins.


Digital multimeter appears lpx2148 have measured voltages lower than expected. Dec 242: And what would be the program? Writing to this register places corresponding values in all bits of the particular PORT pins. Writing 0s has no effect.

led interfacing with ARM7 ( LPC2148 )

By this, the first 16 P0. Losses in inductor of a boost converter 9.

Reading this register returns the current contents of the port output register, not the physical port value. Please enable JavaScript to view the comments powered by Disqus. I mean, what chapters do I need from datasheet to program in C? Now, using the steps given here, try to program on your own and once it is done, compare with the basic program given here.

Every GPIO pin has a minimum of one function and max of four functions.

C program of led interfacing with ARM7 ( LPC )

Somebody please upload or link few more codes to learn step by step. The below sample code shows how to use the GPIO functions. Y where X stands for port number, 0 or 1 where else Y stands for pin number 0 to How reliable is it? How ppc2148 you get an MCU design to market quickly? The current state of the GPIO configured port pins can always be read from this register, regardless of pin direction. Choosing Battery for Robots. This register controls the state of output pins.


As there can be up to 4 functions associated with a GPIO pin, two bits for each pin are available to select the function. This register individually controls the direction of each port pin. How would I learn C language specified for this particular microcontroller?
