ARM based microcontrollers are advanced set of processors and hence for beginners, it might be a little difficult to understand. It is advised to start with smaller and simpler microcontrollers like to get the idea of how a microcontroller works, programming a microcontroller and developing applications using microcontroller. As the interest in advanced microcontrollers like ARM is continually increasing, we have designed a set of tutorials that guide you through the understanding of the basic ARM Processor. Before jumping in to the advanced processors like Cortex — M or Cortex — A series, it is best to start with simple processors like ARM7. If we understand the basic ARM7 processor, it will be very easy to develop applications and systems using advanced processors. The following is a brief introduction to all the tutorials which are explained in this series.

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. 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.
Writing 1s produces lows at the corresponding port pins. Output: Writing to this register places corresponding values in all bits of the particular PORT pins. Input: 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.

Basic ARM Tutorials For Beginners
Every electronics engineer loves to break electronics things and explore what is present inside it. ARM based microcontrollers are heavily used in various types of embedded products and systems. Arm holdings is a British company who developed this architecture and licensed it to other companies, who design their own product by using this architecture. This board is a good choice for beginners and also can be used in high end applications because of its inbuilt peripherals.

Have you looked at the examples, appnotes, etc, provided by the manufacturer and others on the web? When you are new to any device, the first thing to do is to study the documentation - that includes the datasheet , user manual s , application notes, examples, etc provided by the manufacturer. Many 3rd parties also have examples, tutorials, etc: www. OK,thanks for Your reply.. If you haven't done the basic study, you wouldn't understand it even if I did give it to! I am on the of track of learning And the question we all wonder about - when is your project due to be handed in?
