Demonstration board electrical connection

The firmware library supports two demonstration boards:

1.

STEVAL-PCC009V2 universal USB to serial bus interface

2.

STM32F100 value line Discovery kit

In the case of STEVAL-PCC009V2, the connection of the L6470 demonstration board is

simple. It is only necessary to use a 10-wire flat cable connection line inserted into J1 on

STEVAL-PCC009V2 and J10 on the L6470 demonstration board. The signals are assigned

according to the appropriate section in the dSPIN.h file, see Table 1:

Microcontroller peripherals for the STM32F100 value line Discovery kit connection have

been selected according to Table 2. The user is free to modify the assignment according to

their needs. The condition for correct functionality is consistency between physical

connection and dSPIN.h file content.
