In mbed-src revision 17 there is a bug in Ticker.h line 161 in the attach_us() function: <<code>> /** Attach a member function to be called by the Ticker, specifiying the interval in micro-seconds * * @param tptr pointer to the object to call the member function on * @param mptr pointer to the member function to be called * @param t the time between calls in micro-seconds * * @returns * The function object created for 'tptr' and 'mptr' */ template<typename T> pFunctionPointer_t attach_us(T* tptr, void (T::*mptr)(void), unsigned int t) { pFunctionPointer_t pf = _chain.add(mptr, tptr); setup(t); return pf; } <</code>> The call to _chain.add() has the arguments the wrong way around, should be <<code>> _chain.add(tptr, mptr); <</code>> This is caught by the compiler when attempting to use that function. No test coverage for this function?

Hello, thank you for reporting this bug, I corrected it and it should be available in next revision. Regards,\\ 0xc0170
