I meant keil here but understanding C is the basic step and no ide like keilc, arduino ide, avr ide, arm. It doesnot matter.
You can use any ide as C language is common may be small differences
Want to study C Program development with me
Arduino is ok. I started with arduino. But i came to understand that to study deep programming and skill you should throw away arduino.
Its true that arduino has a large community. But many will lacks knowledge of hardware and software as all are readymade and no companies needs such copycat skills.
Debugging skill is the main objective of any software development
We must understand bit manupulation
All major protocols like serial com, spi, i2c, Can protocol, 1 wire protocol,etc.
C is the universal language for any embedded systems if you know C its easy to compact to use with a variety of microcontrollers like PIC,ARM,ATMEL, 8051 and many others.
Once we understand the hardware part atleast one ic itself. You can see all others resembles the same only architecture differes
You can use arduino ide / arduinodroid app to test the c is working by modifying c code.
What is bit manupulation?
Bit manipulation is the process of manipulating individual bits or groups of bits in a binary representation of data. It involves performing logical and arithmetic operations on binary digits or bits to achieve a desired result.
How to Perform Bit Manipulation?
Bit manipulation is performed using bit-wise operators, which operate on individual bits in a binary representation of data.
Bitwise AND (&): This operator returns a 1 in each bit position where both operands have 1 and 0 in all other positions.
Bitwise OR (|): This operator returns a 1 in each bit position where either or both operands have 1 and 0 in all other positions.
Bitwise XOR (^): This operator returns a 1 in each bit position where the corresponding bits of either but not both operands are 1, and 0 in all other positions.
Left shift (<<): This operator shifts the bits of the first operand to the left by the number of positions specified in the second operand, filling in the empty positions with 0s. For example, 5 << 2 would result in 20 because 5 is represented as 101 and shifting it left by 2 positions results in 10100.
Right shift (>>): This operator shifts the bits of the first operand to the right by the number of positions specified in the second operand, filling in the empty positions with 0s.
Bitwise complement (~): This operator returns the complement of the operand, which means it flips all the bits from 0 to 1 and from 1 to 0.Bit manipulation has a wide range of applications in computer programming, computer science, and digital electronics
Application of Bit Manupulation
Optimization of code: Bit manipulation can be used to optimize code by reducing the amount of memory and processing power required for certain tasks.
Cryptography: Bit manipulation is used extensively in cryptography to encode and decode messages, also generate keys, and perform other security-related work.
Networking: Bit manipulation is used in networking protocols like TCP/IP (Transport Control Protocol / Internet Protocol) to encode and decode packets of data, perform error correction, and perform other tasks related to data transmission and network security.
Digital signal processing: Bit manipulation is used in digital signal processing (DSP) to process and analyze digital signals.
Hardware design: Bit manipulation is used in digital electronics to design and implement digital circuits, processors, and other hardware components.
