Transport PS4BT to ESP32

[yokozawa766]

I used PS4BT on Arduino UNO R3 + USB Host Shield 2.0 + Bluetooth Dongle to interface with Dualshock4, PS4 controller. It works well for Bluetooth Remocon Tank, but Host Shield uses many IOs in UNO and cannot use enough pwm GPIO, so i'm trying ESP-WROOM-32 for this tank. But I cannot. Would you someone transport PS4BT libraries into ESP32 usage ? ESP32 have BT interface inside and more than 16 PWM GPIO that is attractive.
