Where I describe the function - analogRead().

Introduction#

The function analogRead() is similar to digitalRead(), in the sense, it takes a pin number as a parameter and returns the pin’s value. In the case of analogRead, the value will be a number …

Where I describe the struct, buttons[] and how to use it to debounce and check for button presses.

Introduction#

Describing buttons[] is slightly different than describing a function such as analogWrite() and digitalRead() as buttons[] is a struct. The …

Where I describe the function - digitalRead().

Introduction#

The function digitalRead() is analogous to digitalWrite(), in the sense, it takes a pin number as a parameter and as compared to setting its value, it returns the pin’s value. The value …

Where I describe the function - pinMode().

Introduction#

The function, pinMode() is one of the most important and one of the most forgotten of all of the Arduino framework. It is important, as it sets the function of the pin in question. And when its …

Where I describe the function - digitalWrite().

Introduction#

The digitalWrite() function is a basic building block of using a microcontroller. The function will either raise the value of an output pin to 5V or it will lower it to GND (0V), and in doing so …

Where I attempt to gather in one place, all of the errors found while building (compile/link/locate) and uploading code to the Uno.

1. Everytime, I run make, I get an error from Makefile like “Makefile:65: *** missing separator. Stop.” or …

Where I describe the functions for serial input/out - puts(), getchar() and printf().

Introduction#

The serial input/output capabilities of C are vastly superior to those in the Arduino framework. In order to communicate via the USB serial cable, you must …

Where I describe the function - analogWrite().

Introduction#

While analogWrite can be an easy function to use, its not easy to initially understand. This stems from a couple of reasons, first, its mis-named in that the function is not doing anything from …

Where I describe how to use the Library functions in AVR_C.

Introduction#

This page describes where to find specific functions for programming an AVR microcontroller in Standard C using functions similar to the Arduino Language Reference. In this case, the …
