Application Specific Microcontrollers FAQ

What is the purpose of the TS2000 User Module?

The TS2000 User Module enables haptic feedback effects based on Immersion TouchSense 2000 technology, allowing the generation of tactile sensations via actuators like ERM motors.

How does the TS2000 module affect CPU loading?

CPU loading depends on the configuration. In interrupt mode, the CPU is not blocked during effect playback. In polled mode, the TS2000_bUpdate API must be called every 5 ms, increasing software overhead.

Which actuators are supported by the TS2000 module?

The module supports two actuator models: Sanyo NRS-2574i for devices under 150g and Jinlong Z6DL2A017000B for heavier devices.
