C, SPI, CAN or LIN – in terms of interaction with the outside world for
embedded systems, it is safe to say that these are the most commonly used
communication protocols. The new HMO3000 series by HAMEG Instruments
offers you hardware-accelerated signal triggering and decoding for all of these
protocols. You can upgrade your instrument via software licence keys with those
functions required to develop your application:
