Hallo,

i am new to Programming
i have a register file with FPGA_ADC_SEQ1 0x0C00513C
0x0C00513C What does this Hexadecimal represents and how to understand it?

 

A decimal number such as 789 is (7 x 100) + (8 x 10) + (9 x 1)
or (7 x 10^2) + (8 x 10^1) + (9 x 10^0)

A binary number such as 1011 is
(1 x 2^3) + (0 x 2^2) + (1 x 2^1) + (1 x2^0)

Hence a hexadecimal number such as 05CF is
(0 x 16^3) + (5 x 16^2) + (12 x 16^1) + (15 x 16^0)

Thus, each digit represents a multiple of a radix raised to a certain power.

In programming, hexadecimal notation is used to assist the reader in recognizing a binary value. All numbers on a computer are binary.
The programmer needs to take no further action.

Thanks i understand with your examples but what does this represent 0x0C00513C here should i only consider 513C

No.
0x0C00513C likely represents a memory address. You use the entire value. There is nothing for you to do because the compiler understands what it means.

 

If it didn’t have the FPGA prefix I’d have thought that it was the register that controlled an A to D converter, and the bits represent which analogue inputs are to be scanned in sequence #1, and probably selects the input that triggers sequence #1 and the sampling rate.
