WebbI2C.writeto(addr, buf, *, stop=True) Write the bytes from buf to the slave specified by addr. The stop argument (only available on WiPy) tells if a stop bit should be sent at the end of the transfer. If False the transfer should be continued later on. On WiPy the return value is the number of bytes written. Otherwise the return value is None.
