HID 太鼓输入硬件/太鼓控制器 Taiko IO Board / Taiko Controller

分为双鼓与单鼓硬件，双鼓设计用于街机或两个鼓的场景，单鼓的硬件则是双鼓硬件简单地切去一半输入前端设计的，在硬件上两者并无很大的差异。

整体系统分为传感器（鼓）、前端、采样、USB、PC，其中前端、采样、USB三部分位于input硬件上。 除此之外还，有电源、滤波电路等未在结构图中体现。

前端电路采用了与SIF Board近似的设计，先进行信号的放大与积分，再限制输出。

由于来自压电传感器的信号带宽高且信号幅值小，不宜直接进行采样。前端电路将输入信号处理成便于采样的信号。 在示波器截图中，C1(黄色)为传感器输出，C3（红色）为经过前端电路处理后的信号，C2（蓝色）为程序识别后的输出。

硬件分为双鼓硬件和单鼓硬件，双鼓硬件为完整版的硬件，可以用于街机环境。 单鼓硬件为双鼓硬件删去一半输入电路的硬件，软件上兼容了更多的单人应用场景。

Taiko-Input: common questions

What microcontroller does the Taiko-Input use?

The Taiko-Input is built around the STM32G030C, from the STM32 family.

How big is the Taiko-Input PCB?

The Taiko-Input measures 85 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Taiko-Input?

235 components, from 47 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Taiko-Input design files?

From the AnalogDragon/Taiko-Input repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Taiko-Input design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Taiko-Input without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
