Echelon FTXL - Manual (Page 26)

14 Introduction to FTXL
• The FTXL hardware abstraction layer (HAL) files, which you might
need to modify
• The FTXL operating system abstraction layer (OSAL) files, which you
might need to modify
• The FTXL non-volatile data (NVD) driver files, which you might need
modify
• The FTXL LonTalk protocol stack
Because an FTXL device is comprised of both hardware and software
components, different people can be involved in the various steps, and these steps
can occur in parallel or sequentially. The figure does not imply a required order
of steps.
