开始错误为error: #error NO CHIP DEFINED，
然后在网上找解决办法，在predefine 中添加CHIP_5502，
然后却出现了4个错误：
errors encountered during linking; "test1.out" not built test1 line 0 1346844869040 34
unresolved symbol __CSL_init, first referenced in ./DEC5502_DARAM.obj test1 line 0 1346844869040 33
unresolved symbol _CSL5502_LIB_, first referenced in ./DEC5502_DARAM.obj test1 line 0 1346844869039 31
unresolved symbol _PLL_setFreq, first referenced in ./DEC5502_DARAM.obj test1 line 0 1346844869040 32
请问大家有谁知道错误原因吗。。。
