What is bitRead command?
The bitRead command returns the bit value of the bit index requested. Syntax. var = bitRead( byteValue , bitIndex )
What does bitRead do in Arduino?
Returns. The value of the bit (0 or 1).
How do you shift bits in Arduino?
Description. There are two bit shift operators in C++: the left shift operator << and the right shift operator >>. These operators cause the bits in the left operand to be shifted left or right by the number of positions specified by the right operand.

What is a Type in Arduino?
Advertisements. Data types in C refers to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in the storage and how the bit pattern stored is interpreted.
What does |= mean in Arduino?
compound bitwise OR operator
Description. The compound bitwise OR operator |= is often used with a variable and a constant to “set” (set to 1) particular bits in a variable.
What is operator in Arduino?
Advertisements. An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. C language is rich in built-in operators and provides the following types of operators − Arithmetic Operators.
How do you call a function in Arduino?
Calling a Function To call a function, use the function name followed by opening and closing parentheses. Finally terminate the statement that calls the function with a semicolon. Load the sketch to an Arduino and then open the terminal window.
Can you have an if statement inside an if statement Arduino?
You can have a single if statement with no else or if else statements however, if you want else or if else statements then you need to have an if statement.
Does Arduino Uno have WiFi?
The Arduino Uno WiFi is an Arduino Uno with an integrated WiFi module. The board is based on the ATmega328P with an ESP8266WiFi Module integrated. The ESP8266WiFi Module is a self contained SoC with integrated TCP/IP protocol stack that can give access to your WiFi network (or the device can act as an access point).
What is an example of bitread ()?
Name bitRead () Examples byte x = 33; byte a = bitRead (x, 5); Description The bitRead command returns the bit valu Syntax var = bitRead ( byteValue, bitIndex ) Parameters byteValue byte: the byte from which read
What is the maximum bit you can shift in bitread?
Here’s reference on >>, which is used in bitread: variable – (byte, int, long) number_of_bits integer <= 32 So the bit you shift can be as many as 32. So 32 is your max in bitread’s bit. They only create problems when you don’t pay attention.
How to read first two bits and offset the first bit?
If you want to read the first two bits, you just need to mask them off like so: If you want to offset it you need to shift right N bits and then mask off the bits you want: To read three bits like you asked in your question. Show activity on this post.
How to read the first two bits of an array?
If you want to read the first two bits, you just need to mask them off like so: If you want to offset it you need to shift right N bits and then mask off the bits you want:
