I'm looking for more speed than basic_i2c_driver can give me. Does anyone have an assembly language driver?

    There is an assembly language I2C (and low level SD card) driver that's part of FemtoBasic in the file sdspiFemto.spin. It's designed to be used separately and, with some minor changes to the Spin interface routines, can do overlapped buffered I/O. The current Spin interface routines wait for any ongoing operation to finish before continuing or returning. Read the extensive comments at the beginning of the file for details.
