| + | ====== Firmata Library ====== | ||
| + | |||
| + | 通过Firmata程序库执行Firmata协议，在主机电脑上可与软件进行沟通。当您正在使用时，这允许您可以编写自定义固件而无需创建你自己的协议和对象的编程环境。 | ||

| + | ===== 回调函数 ===== | ||
| + | |||
| + | 为了给信息类型附上一个函数，你的函数必须匹配标准的回调函数。\\ In order to attach your function to a message type, your function must match the standard callback function. | ||
| + | |||
| + | 目前有三种类型的回调函数：generic, | ||
| + | \\ There are currently three types of callback functions in Firmata: generic, string, and sysex. | ||
| + | |||
| + | *generic | ||
| + | \\ void callbackFunction(byte pin, int value); | ||
| + | |||
| + | *system_reset | ||
| + | \\ void systemResetCallbackFunction(void); | ||
| + | |||
| + | *string | ||
| + | \\ void stringCallbackFunction(char *myString); | ||
| + | |||
| + | *sysex | ||
| + | \\ void sysexCallbackFunction(byte pin, byte byteCount, byte *arrayPointer); | ||
| + | |||
| + | *Message Types | ||
| + | \\ These are the various message types that you can attach functions to. | ||
| + | \\ 这些是不同的消息类型, | ||
| + | |||
| + | *ANALOG_MESSAGE | ||
| + | \\ the analog value for a single pin | ||
| + | \\ 模拟值为一个单独端口。 | ||
| + | |||
| + | *DIGITAL_MESSAGE | ||
| + | \\ 8-bits of digital pin data (one port) | ||
| + | \\ 8位数的Pin数据（仅限一个端口） | ||
| + | |||
| + | *REPORT_ANALOG | ||
| + | \\ enable/ | ||
| + | \\ 启用/ | ||
| + | |||
| + | *REPORT_DIGITAL | ||
| + | \\ enable/ | ||
| + | \\ 启用/ | ||
| + | |||
| + | *SET_PIN_MODE | ||
| + | \\ change the pin mode between INPUT/ | ||
| + | \\ 在INPUT/ | ||
| + | |||
| + | |||
| + | *FIRMATA_STRING | ||
| + | \\ C-style strings, uses stringCallbackFunction for the function type | ||
| + | \\ C样式的字符串，使用stringCallbackFunction函数类型 | ||
| + | |||
| + | *SYSEX_START | ||
| + | \\ generic, arbitrary length messages (via MIDI SysEx protocol), uses sysexCallbackFunction for the function type | ||
| + | \\ 通用的、任意长度的消息(通过MIDI SysEx协议), | ||
| + | |||
| + | *SYSTEM_RESET | ||
| + | \\ message to reset firmware to its default state, uses systemResetCallbackFunction for the function type | ||
| + | \\ 消息重置固件到默认状态, | ||
