I set IQmathLib.h as the floating point library and saw the following lines of code in IQmathLib.h, #if MATH_TYPE == FLOAT_MATH #include
#include#endif #define _IQsin(A) sin(A) Does it mean that after...
I encountered a big problem when testing someone else's USB simulation model. I used the data transmission module I wrote to simulate the data transmission of the USB HOST and sent the data to the sim...
