Aw, yiss…BiSS!

BiSSThere’s a cool new serial data interface coming on the scene.

It’s called BiSS (Bi-Directional Synchronous Serial), and is an open-source, free-to-license digital interface for sensors and actuators. BiSS is hardware compatible to the industrial standard SSI (Serial Synchronous Interface) but offers additional features and options. Here are a few highlights:

  • Serial Synchronous Data Communication
  • 2 unidirectional lines Clock and Data
    o Cyclic at high-speed (up to 10 MHz with RS422 and 100 MHz with LVDS)
    o Line delay compensation for high-speed data transfer
    o Request processing times for data generation at slaves
    o Safety capable: CRC, Errors, Warnings
    o Bus capability for multiple slaves and devices in a chain
  • Unidirectional
    o BiSS C (unidirectional) protocol: Unidirectional use of BiSS C
  • Bidirectional
    o BiSS C protocol: Continuous mode
  • Actuators
    o Operate actuators via two additional lines
