4.2.2 TRINAMIC Real-Time Monitoring Interface (SPI Master)
The TRINAMIC Real-Time Monitoring Interface (RTMI, SPI Master) is an additional fast interface enabling
real-time identification of motor and system parameters. The user can check configuration and access
registers in the TMC4671 via the TMCL-IDE with its build-in configuration wizards for FOC setup in parallel
to the user firmware. TRINAMIC provides a Monitoring Adapter to access the interface, which connects
easily to a single 10 pin high density connector (Type: Hirose DF20F-10DP-1V) on the user’s PCB or on the
evaluation board. If the interface is not needed, pins can be left open or can be used as GPIOs according
to the specification. The connector needs to be placed near the TMC4671. Its assignment is pictured in
figure 11.
