Using the EVAL6474H-DISC with the firmware library

(FW L6474)

The L6474 firmware library is supplied as an IAR workspace with a source, including project

files. If you are using the IAR design environment, you just need to load the “easyspin.eww”

file and use the “fwlibrairies_easyspin_discoverykit” project which is already active.

If you are using a different design environment, you will find instructions in this user manual

to build a new project on your preferred IDE.

The L6474 firmware library is also supplied as an executable in the HEX and in DFU format.

It can be loaded into the EVAL6474H-DISC board as explained in Section 5.2.

FW L6474 library description

The FW L6474 library has the following features:



Device configuration



Motion commands



FLAG interrupts management



Button interrupts management



“Daisy Chain” mode

The FW L6474 library has been tested on the L6474H Discovery board. The main program

contains a commented demonstration sequence which uses most of the FW L6474 library

supported features.
