Example usage: #include "CCRTOS.H" void TaskN (void *pdata) { U16 version; U8 Major, Minor; .... version = CoGetOSVersion(); // Get Major Version Major = ((version>>12)&0xF) * 10 + (version>>8)&0xF; // Get Minor Version Minor = ((version>>4)&0xF) * 10 + version&0xF; printf("Current OS Version: %d.%02d\n",Major, Minor); .... } Note: CoGetOsVersion() returns a 16-bit binary number. Shift it 8-bit to right and you can get the actual version. In other words, version 1.01 would be returned as 0x0101. 46
