已經(jīng)提出了許多解決方案來克服Raspberry Pi的這一限制。很多人為此目的使用支持 I2C(內(nèi)部集成電路)或 SPI(串行外設接口)的附件。這些設備由 Raspberry Pi 控制,它們生成 PWM 信號用于控制目的。PWM 發(fā)生器附件也可用于將支持 PWM 的輸出引腳添加到 Raspberry Pi。
正在使用的另一種方法是在其他支持 GPIO 的引腳上執(zhí)行軟件 PWM。WiringPi 庫是一個允許這種類型控制的示例庫。它使用實時調(diào)度程序通過運行各個線程來優(yōu)先生成 PWM 信號,但由于 Raspberry Pi 上使用的操作系統(tǒng)執(zhí)行多任務處理,因此該解決方案不適合,因為它提供了低時序分辨率和高抖動。
