• The TMC424 is a triple incremental encoder input chip, which interfaces to any SPITM compatible controller. The TMC424 can especially be used in conjunction with the TMC429 triple stepper motor controller to provide position verification or stabilization using some additional software. It integrates 24 bit counters for each encoder to provide a high position resolution without CPU interaction. Further it allows dynamic resolution adaptation to allow direct comparison of encoder counters with mot.
