   * For the new build, hold the BOOTSEL button while connect the USB to a PC, there will be a disk named "RPI-RP2" showed up. Drag the UF2 firmware binary file into it. That's it.
   * If there's already a working firmware, you can use "update" command in command line to update the firmware in the future, so you don't need to open the housing.
   * If there's already a working firmware later than 2023-12-02, you can also press "00" key and "·" key (or directly ground the GPIO10 and the GPIO11) at the same time when plug in the USB cable, it will boot into firmware update mode.

-* Spicetools cardio (Card I/O) HID is supported;
-* SEGA AIME protocol is supported on a second serial port.
+* The other serial port is for reader protocol, currently SEGA AIME and Bandai Namco are supported.
+* Spicetools cardio (Card I/O) HID is always enabled unless a reader protocol is active;
+* If your PN5180 module has an issue with Mifare (Such as AIME and Bana Passport) reading, you can try enable the PN5180 TX tweak by "pn5180_tweak on" command.
 * Some command line commands:
   * "light \<rgb|led|both|off\>" to turn on or off the LEDs.
   * "level <0..255> <0..255>" to adjust the brightness.

   * 对于新构建，握住 BOOTSEL 按钮，同时将 USB 连接到 PC，会出现一个名为 "RPI-RP2" 的磁盘。将 UF2 固件二进制文件拖入其中。这样就 OK 了。
   * 如果已经上传过可用的的固件，你可以在命令行中使用 "update" 命令来更新未来的固件，这样你就不需要打开外壳。
   * 如果已经有一个在 2023-12-02 之后的工作固件，你也可以在插入 USB 线时同时按下 "00" 键和 "·" 键（或直接接地 GPIO10 和 GPIO11），它将进入固件更新模式。
