Data structures
a user-defined data type that allows you to group together different variables, defines, functions, arrays etc. under a single name. Each is called a field and can be used to model or describe a real object.
What is a structure?
ATMEGA328P
What microcontroller is embedded in the Arduino board?
ON THE BOARD!
one line of code that would make Port C bits 1 and 3 in input mode without changing any other direction bits?
DDRC &= ~0x0A
An example of how, in computational programming, utilizing fixed point math involves representing and manipulating numerical values with a predetermined number of decimal places.
to simplify algorithmic calculations, such as in a sin table, or in audio processing, or just to simplify money calculations by doing everything in cents and placing the decimal sign to separate cents from dollars at the very end.
typically an array that stores precomputed values or results for specific inputs. Instead of recalculating these values every time they're needed, the program can simply look them up in the table.
what is a lookup table?
This type of memory on an Arduino Uno board is used for storing the program code, commonly referred to as the sketch.
for an extra 100 points, name another type of memory on an arduino board
What is flash memory?
bonus: SRAM, EEPROM,
A line that will write a logic HIGH to Port D bit 4 is the pin is already configured as an output
PORTD |= 0x10;
digitalWrite(4, HIGH);
In this type of computer architecture, instructions tend to be complex, allowing multiple operations to be performed in a single instruction, often resulting in fewer instructions needing to be sent to the processor and reducing bottlenecks
What is CISC (Complex Instruction Set Computing)?
a file that stores important function definitions and other info related to a particular board or program. Usually contains a header guard such as
#ifndef Arduino_h
#define Arduino_h
What is a header file?
This protocol serves a crucial role in facilitating bidirectional serial communication between the Arduino and external devices, enabling tasks such as data transmission and synchronization with the host via USB connection
What is USART?
certain memory addresses are assigned to represent control and data registers of peripheral devices, such as sensors, LEDs, or motors, instead of using separate instructions for I/O operations. In Arduino, this means that you can interact with external devices by reading from or writing to specific memory addresses, similar to accessing variables in your program
What is memory mapped I/O?
In this type of computer architecture used by the Arduino, instructions are simplified, executing fewer operations per instruction, but sending more total instructions into the processor
What is RISC (reduced instruction set computing)
structure.field and
structure-> field respectively
what are pass by value and pass by reference?
For smaller-scale embedded projects requiring real-time control and low power consumption, you might opt for this microcontroller platform. Meanwhile, for projects demanding higher processing power, multimedia capabilities, and advanced computing tasks, you'd likely lean towards this single-board computer platform.
What are the Arduino and Raspberry Pi respectively?
In C programming, this data structure consists of a sequence of elements where each element points to the next, forming a chain-like structure.
What is a linked list?
Two specialized registers on the arduino that don't set or clear I/O pins
status register (SR or SREG), program counter (PC) and Stack pointer (SP)
