Hello

I am struggling to generate random number in term of binary number such as 1 and 0. Bascially I would like to generate 1 or 0 up to max 10 binary in C (for example, 1010111101). I would be very grateful if someone can provide me simple code in C.

Hi,


try with "rand" function in C.

Example:

#include <stdlib.h>
unsigned int result;

.....


result = rand(0x1111);


here it is from Keil help:

The rand function returns a random number in the range 0 to +32767. The random number generator is reinitialized each time a non-zero value is passed in the seed argument. You may use the rand function to delay for a random number of clock cycles or to generate random data to feed into a particular algorithm or input routine.

Example
>rand (0x1234) /* Initialize random generator with 0x1234 */
0x3B98

>rand (0) /* No initialization */
0x64BD


BTW: Which mcu u r using?!?
