• SCCB(Ⅲ) — Protocol Structure

    We covered SCCB protocol signaling in previous post, and we will dive into the SCCB structure in this post. Below is the diagram of SCCB, it shows one master device connects to one slave device. Multiple slave devices can be connected to the same bus. Master Device Both SCCB_E and SIO_C are driven by the…

  • SCCB (Ⅱ) — Protocol Signaling

    After an overview of the SCCB protocol, we will dive into SCCB signaling in details. Below is the Pin description from the specification: SCCB_ESCCB_E is an active-low, one-directional signal controlled by the master device. During data transmission, SCCB_E must be set to 0; When bus is idle, the SCCB_E must be set to 1. SIO_CSIO_C…

  • SCCB (I) — A Protocol in Image Sensor

    Serial Camera Control Bus (SCCB) is defined and deployed by OmniVision Technologies, Inc. Most of the functions in OmniVision image sensors can be controlled by SCCB. The image sensor will be used as a slave device, and one master device will connect to at least one slave device; below is the 3-wire SCCB Functional Block…
