YOLO(You Only Look Once)是一种流行的物体检测和图像分割模型,由华盛顿大学的Joseph Redmon 和Ali Farhadi 开发。 YOLO 于2015 年推出,因其高速和高精度而广受欢迎

The eCAP module represents one complete capture channel that can be instantiated multiple times, depending on the target device. In the context of this guide, one eCAP channel has the following independent key resources: • Capture inputs can be connected using the Input X-BAR • 256:1 input multiplexer • Output X-BAR is used to configure output in APWM mode • 32-bit time base (counter) • 4 x 32-bit time-stamp capture registers (CAP1-CAP4) • Four-stage sequencer (modulo4 counter) that is synchronized to external events, eCAP pin rising/falling edges. • Modulo counter status register (MODCNTRSTS) to indicate sequencer state • Independent edge polarity (rising/falling edge) selection for all four events • Input capture signal prescaling (from 2-62 or bypass) • One-shot compare register (two bits) to freeze captures after 1-4 time-stamp events • Control for continuous time-stamp captures using a four-deep circular buffer (CAP1-CAP4) scheme • Interrupt capabilities on any of the four capture events • Separate DMA trigger • EALLOW protection to control registers • Signal monitoring capability for edge, pulse width, and period • DMA event generation capability in APWM mode • ADC SOC event generation capability, to trigger ADC conversion 21.3 Configuring Device Pins for the eCAP The Input X-BAR connects the device pins to the module as input. Any GPIO on the device can be configured as an input. The GPIO input qualification can be set to synchronous or asynchronous mode by setting the GPxQSELn register bits. Using synchronized inputs can help with noise immunity but affects the eCAP accuracy by ±2 cycles. The internal pull-ups can be configured in the GPyPUD register. Since the GPIO mode is used, the GPyINV register can invert the signals. New to the Type 1 eCAP module, a 128:1 input multiplexer must also be configured (see Figure 21-3). This multiplexer can select a variety of inputs detailed in Table 21-1 by configuring ECCTL0.INPUTSEL.
