I would like to ask if somebody knows what compiler is used if I compile my project online? In my project there are octal and binary number constants 514 in binary format e. Anyway, is there a documentation available about the compiler? You cannot use that notation to refer to integers in C. As far as I know you can octal and binary number constants 514 chars i. You should convert all the binary constants to either hex or decimal.

Hex would be easier because each nibble in a binary word corresponds to a digit in hex. An easier change may a simple BinToHex convertor routine. Here's a simple, naive version, which could be improved on in various ways:. Pass in a string of '1' and ''0' characters, and it hands you back the unsigned 32 bit number.

It can of course be optimised, but it demonstrates the concept. This octal and binary number constants 514 uses cookies to store information on your computer.

Hello, I would like to ask if somebody knows what compiler is used if I compile my **octal and binary number constants 514** online? OK, I started it earlier, but the problem is that a bitmap for an lcd is encoded in this format I would be happy if I wouldn't have to rewrite all byte to hex.

If the value of the three bits is greater than or equal to five, add binary three to the number and shift the result one bit to the left. If the value of the three bits is less than five, shift one bit to the left without adding three. Take the next bit from the right and repeat the operation until reaching the least significant bit, which will be carried over without decoding. The E4 decoding block is effectively a look-up table with the relationship between the four input bits and the four output bits provided by truth-table Although the E4 decoding tree in FIG.
