Im very noob at this electronics, Iam studying by myself...
please answer it nicely and easily to understood.
Question:
What is the purpose of HEX codes in electronics? why do i need
to program an IC? or is it possible to program it?
Anyone who works with digital electronics need to memorize these 16 mappings. Once you have done so you can look at at multi digit hex number and know which bits are on and off.0b0000 0x0
0b0001 0x1
0b0010 0x2
0b0011 0x3
0b0100 0x4
0b0101 0x5
0b0110 0x6
0b0111 0x7
0b1000 0x8
0b1001 0x9
0b1010 0xA
0b1011 0xB
0b1100 0xC
0b1101 0xD
0b1110 0xE
0b1111 0xF
Because some chips are actually a complete "computer" on a chip. These are called microcontrollers.I notice some of Circuits need programming why do I need to do that..
Mike, I think 'translation language' is about as bad a description for hex as you can get. (no offense) It's a numbering system. It's just like counting from 1 to 10 only there are more digits than we're used to. Some early computers were 4 bit computers so hex code lent itself readily to viewing the code as each 'digit' represents 4 bits (otherwise known as a nibble) When 8 bit computers came along they simple used two letters spaced a little distance apart to represent all the possible byte values. These two paired digits are also commonly called a 'byte word' Modern computers of a 'word' length of up to 64 bits on the latest Intel and AMD chips.

Personally I have no problem with binary I find it significantly easier to deal with than hexidecimal actually.
