描述
嚴格來說,SoftServo-B10CH 是一款 10 通道 PWM 信號發生器,可應用於大多數集成了 RC 接口的設備,但設計的初衷是控制 PWM 型伺服。它將 RS485 和 I2C 集成到一個連接器中,並且它們共享相同的用戶寄存器,所以伺服控制器可以隨時通過兩個接口中的任何一個使用。所有功能都可以通過讀寫用戶寄存器來執行,除了一些特殊操作(詳細請參考相應的通信協議),這與 MCU 操作類似。此外,PWM 信號的高電平寬度簡化為 PWM 有效寬度,典型值為 500μs 至 2500μs。

特徵:

  • 所有 PWM 信號同時輸出(換句話說,它們幾乎具有相同的上升沿),實際分辨率高達 1μs(硬件版本必須高於 V12)。
  • 信號耦合非常低,難以直觀檢測,就像所有 PWM 信號由單獨的硬件產生一樣。
  • 它集成了軟啟動功能。眾所周知,PWM 型伺服器的初始位置通常是未知的。常規啟動模式使伺服以全速旋轉到目標位置,這在大多數機器人應用中是不令人滿意的。軟啟動模式可以使伺服在當前位置未知時緩慢旋轉,但在短時間內需要更多電流。建議在需要控制多個伺服時,所有舵機都應以分時模式啟動,以減少電流。
  • 週期,最小 PWM 有效寬度和最大 PWM 有效寬度可以靈活設置,這使得所有 PWM 式伺服系統都可以兼容。
  • 它基於細分算法,最大細分值可達 250.每個通道的位置和速度可以單獨控制,這對機器人的動態控制起著傳導作用。速度取決於細分(見下文)。
  • 所有的 PWM 信號可以在任何時候通過將等效位置值設置為 251 來終止,這對於保護伺服非常有用。
  • 它集成了一個穩定和高效率的 RS485,波特率可以自動檢測。當波特率不高於 28800bps 時沒有指令丟包,否則第一個指令報文將被丟棄。此外,建議當波特率高於 28800bps 時首先發送同步字節(0xff 0xff 0xff 0xff)。
  • 它集成了一個穩定的高效率 I2C。

電源電壓:DC 5〜12V

Description
Strictly speaking, SoftServo-B10CH is a 10-channel PWM signals generator, which can be applied to most of the devices that integrate RC interface, but the original intention of the design is to control the PWM-Style servo. It integrates RS485 and I2C into one connector, and they share the same user register, so the servo controller can be used via any one of the two interfaces at any time. All functions can be performed by reading or writing the user register, except for a few special operations(please refer to the corresponding communication protocols for details), which is similar to the MCU operation. In addition, the high-level width of the PWM signal is simplified as PWM-Effective-Width which is typically from 500μs to 2500μs.

Features:

  • All the PWM signals output at the same time(in other words, they almost have the same rising edge), and the actual resolution is up to 1μs(the hardware version must be higher than V12).
  • The signal coupling is so low that it is difficult to detect visually, just like all the PWM signals are generated by separate hardware.
  • It integrates the Soft-Start function. As we all know, the initial position of the PWM-Style servo is typically unknown. Conventional-Start mode makes servo rotate to the goal position with full speed, which is unsatisfactory in most robotic applications. Soft-Start mode can make servo rotate slowly when the current position is unknown, but need more current in a short time. It is suggested that all the servos should be started in time-sharing mode to reduce the electric current when you need to control several servos.
  • The cycle, the minimum PWM-Effective-Width and the maximum PWM-Effective-Width can be set flexibly, which makes all the PWM-Style servos compatible.
  • It is based on a subdivision algorithm, the maximum subdivision value is up to 250. The position and the speed of each channel can be controlled separately, which is conductive to robot dynamic control. The speed depends on the subdivision(see below).
  • All the PWM signals can be terminated by setting the equivalent position value to 251 at any time, which is extremely useful for protecting the servo.
  • It integrates a stable and high-efficiency RS485, and the baud rate can be detected automatically. There is no instruction packet loss when the baud rate is not higher than 28800bps, otherwise the first instruction packet will be discarded. Furthermore, it is recommended to send the sync bytes(0xff 0xff 0xff 0xff) first when the baud rate is higher than 28800bps.
  • It integrates a stable and high-efficiency I2C.
