1.2.10.2 Using The Library
The SE Random library is called to obtain a random number with certain characteristics.
The following example illustrates how the Random service can be used.
Example of SE Random library usage
uint8_t rndNum8; uint16_t rndNum16; uint32_t rndNum32; uint8_t rndNum128[16]; /* Generate a random 8-bit value */ rndNum8 = SRV_RANDOM_Get8bits(); SYS_CONSOLE_PRINT("Random 8-bit value: %u\r\n", rndNum8); /* Generate a random 16-bit value */ rndNum16 = SRV_RANDOM_Get16bits(); SYS_CONSOLE_PRINT("Random 16-bit value: %u\r\n", rndNum16); /* Generate a random 16-bit value within a range */ rndNum16 = SRV_RANDOM_Get16bitsInRange(0, 100); SYS_CONSOLE_PRINT("Random 16-bit value between 0 and 100: %u\r\n", rndNum16); /* Generate a random 32-bit value */ rndNum32 = SRV_RANDOM_Get32bits(); SYS_CONSOLE_PRINT("Random 32-bit value: %lu\r\n", rndNum32); /* Generate a random 32-bit value within a range */ rndNum32 = SRV_RANDOM_Get32bitsInRange(1000, 2000); SYS_CONSOLE_PRINT("Random 32-bit value between 1000 and 2000: %lu\r\n", rndNum32); /* Generate a random 128-bit value */ SRV_RANDOM_Get128bits(rndNum128); SYS_CONSOLE_PRINT("Random 128-bit value: "); for (uint8_t i = 0; i < 16; i++) { SYS_CONSOLE_PRINT("%02x", rndNum128[i]); } SYS_CONSOLE_PRINT("\r\n");
