Texas Instruments DRV2605L 触觉驱动器
德州仪器 DRV2605L 触觉驱动器是一款低压触觉驱动器，包含一个触觉库并提供一个闭环执行器控制系统，用于 ERM 和 LRA 的高质量触觉反馈。这有助于改进加速一致性、启动时间、制动时间方面的执行器性能，且可通过一根共享的 I2C 兼容总线或 PWM 输入信号进行访问。DRV2605L 器件提供许可版 Immersion TouchSense 2200 软件，这样就无需设计触觉波形，因为软件已包含 100 余种许可效果（6 个 ERM 库和 1 个 LRA 库）以及音频转感应（audio-to-vibe）功能。此外，实时播放模式使主处理器可以绕过库播放引擎，而通过 I2C 直接从主机播放波形。
