3-axis incremental encoder interface with position scaling
The TMC424 is a triple incremental encoder input chip, which interfaces to any SPI compatible controller. The TMC424 can especially be used in conjunction ith 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 motors using different micro step resolution. All encoder counters can be latched synchronously, or whenever a null channel event occurs, providing a position on strobe holding function. The TMC424 the direct successor of the discontinued TMC423.
