Wiegand26 conversion to hex

[Raj]

Hi! Cytron.I am currently doing RFID based projects using CCS Compiler.I have a
question.

In RFID tag, the serial number wiegand 26, for example 0003834274 058,33186
1) How we can change the wiegand number 058,33186 (decimal) to d37e5d (hex)?
Can you give clear explanation.

2)What does buffer means in c compiler? For example
if(buffer[2]==0xd3 && buffer[1]==0x7e && buffer[0]==0x5e) // if card 1 detected

Please reply as soon as possible.

OK, I am not Cytron staff, a lot of member here is not

1st, you need to know what is being received by MCU through weigand. OK, let's assume you get 05833186. Woh... want a clear explanation? Learn it by yourself. Most of us is helping volunteerly, please be polite. Now, answer this: How is 055833186 being store in MCU? Every value is being store with Binary number/value, there is no such thing as decimal or hexadecimal in digital system, it is the compiler that let human write in decimal or hexadecimal. So your question might be how to translate the value into ASCII hexadecimal value?

Buffer is simply name for a place (RAM) reserved to store variables, normally is few bytes to hundreds of bytes depends on the purpose. Sometime we call it heap

In the code you see, it is actually comparing/checking a few element of an array.
