// Enable this mode to pass raw analog data to the game without any post-
// processing.
// The game has a built-in mechanism to calculate which sensor is triggered
// and the force of the hit, so it's recommended to enable this mode.
// This also the provides the most similar experience with the arcade.
// If turned on, the microcontroller will ony do a fast sigle-pass convolution
// over the piezoelectric sensors' inputs, and then pass the data to the game
// directly.

/********************************************************
#define PLAYERS 2
#define CHANNELS 4
ESP32 is not fast enough to process 16 channels of input
simultaneously, so you can choose one of the 2 modes:
// SAMPLE_CACHE_LENGTH must be power of 2 (8, 16, 32, etc.)
// See cache.h for implementation
#define SAMPLE_CACHE_LENGTH 16
- MODE_TWO_PLAYERS: Allows the controller to connect 2
drums, but the sensitivity values are flashed to the
board so you can't adjust them without re-flash the
firmware. If you use the provided board, connect the
2 drums and ignore the adjustable resistors.
// The maximum value of a hit (not the minumum value to trigger a heavy hit)
// To configure the light and heavy thresholds, do it in the game settings
#define MAX_THRES 5000
- MODE_ADJUSTABLE: Allows you to adjust the sensitivity
values with the potentiometer as you play, but only
the P1 side of the board will be enabled (you can
configurate it as 1P or 2P in Params.h file).
