# Some Interesting Designs
These designs are mainly based on observations of game behavior to optimize the gaming experience. They may be reasonable or unreasonable.
## Observations of Game Software Behavior
- Input Frequency Limit: Both the ns platform games and Taiko-Hi have input frequency limits. After testing, it is found that the limits apply independently to each player. For the same player, a single channel has a limit of 30 inputs per second, and all four channels together have a limit of 60 inputs per second. Inputs exceeding this frequency will be discarded.
In other words, if only Left Don or Right Don is struck, a maximum of 30 strikes per second is possible, but if Left and Right Don are struck alternately, it can increase to 60 strikes per second.
- Hardware Limitations of the ns Platform: There is a long filtering period for button inputs, and both the button press and release need to be held for a period of time to take effect.
In ns games, this period needs to be longer than 20ms. However, on the home screen, it needs to be even longer, possibly exceeding 20ms and reaching up to 100ms. This may be because the ns supports variable filtering time.
- Injection of Taiko-Hi Data:
## Cross-Assignment of Outputs

Within an ns game, this period needs to be greater than 20ms. However, on the home screen, it needs to be much greater than 20ms, even up to 100ms, which may be due to variable filtering time supported by the ns.

## Signal Triggering and Crosstalk Detection
When multiple signals are input simultaneously, the channel with the higher amplitude is selected for triggering.
Drum sensors are fixed on several relatively independent wooden boards. In general, direct strikes on the boards produce signals with much higher intensity compared to signals affected by vibration or crosstalk.
Taiko sensors are fixed on several relatively independent wooden boards. In general, direct strikes on the boards produce signals with much higher intensity compared to signals affected by vibration or crosstalk.
The approach here is to introduce a small delay after the first trigger and wait for other channels to trigger. If multiple channels are triggered during this period, the channel with the strongest signal is output.

Digital signal processing mainly involves trigger handling, debouncing, and determining if there is signal crosstalk.
Since the drum contains a physical structure, vibrations can cause signal misfires. Therefore, it is necessary to determine and output the signals received at the same time.

After the signal is sampled, it is recorded as a waveform array, and a trigger function is used to determine if there is a signal with the expected strength.
The delayed output ensures that when a signal arrives, it does not miss the trigger of other sensors. If other channels are triggered during the delay, the triggered values will also be recorded.
The arbitration function determines the maximum strength among the triggered channels during the delay and is used to reset the states of other functions.

### Output Frequency Limitation
The output frequency limitation is mainly due to the hardware or program that receives the data. When it receives data that exceeds its processing capability, packet loss may occur.
After multiple tests, the software input limitation for ニジイロ is a maximum input frequency of 60Hz for all channels and 30Hz for signals of the same color.
The n******o switch limits the input signal time to 20ms (both press and release are around 20ms; values smaller than this may result in sticky inputs).
Other software running on different computers usually doesn't have this convenient limitation, but there is usually a filtering of around 10ms on the selection page.

Other game software running on different computers usually doesn't have this convenient limitation, but there is usually a filtering of around 10ms on the selection page.
### Output Assignment
Due to different functionalities or software operation modes, different software supports different maximum input frequencies. Output assignment is mainly used to make the input frequency reach the upper limit of the device.
The behavior is that when the triggering frequency is high, the input of the same channel will be assigned to another channel. Different devices adopt different approaches.
- For NS: The key debouncing is relatively aggressive. When there is a high-frequency input, it will be assigned to the two adjacent keys on the same side.
- For ニジイロ: The gaming software limits the maximum global input frequency and the maximum input frequency per channel. This may be for easier image calculations. Here, the input frequency for each channel is also limited, and inputs that have the same sound are assigned to idle channels.
Due to different device capabilities or software running methods, different software support different maximum input frequencies. The purpose of allocating the output channels is to achieve the input frequency limit of the particular device.
The behavior observed is that when the triggering frequency is high, inputs from the same channel will be allocated to another channel. Different devices adopt different approaches:
- ns: Aggressive debouncing is performed, and when there are high-frequency inputs, they are allocated primarily to the two adjacent keys on the same side.
- ニジイロ: The game software limits the maximum global input frequency and the maximum input frequency for a single channel. This may be for the convenience of calculating images. Here, the input frequency for a single channel is limited, and inputs of the same type (e.g., same "dong") are allocated to idle channels.
- Other applications on PC (such as Open Taiko): These software programs do not have input frequency limitations, so no allocation is needed.

### Key Mapping
