m2kcli

m2kcli is a command-line frontend for libm2k.

m2kcli is composed from many commands, each representing a major functionality of the ADALM-2000:

  • analog-in: oscilloscope and voltmeter
  • analog-out: signal generator
  • digital: logic analyzer and pattern generator
  • power-supply

m2kcli offers an easy way to communicate with other devices using digital protocols such as:

  • SPI
  • I²C
  • UART
  • UART Terminal

How to install it?

m2kcli and sigrok-cli

Sigrok is a portable, cross-platform, free open source signal analysis software. sigrok-cli is a command-line frontend for sigrok. A a much wider documentation about sigrok-cli can be found on this wiki page.

sigrok-cli can be used for decoding digital signals. m2kcli does not have the functionality of continuously decoding SPI or I²C signals. Using sigrok-cli for decoding the data and m2kcli for capturing the data, we can simulate this functionality.

How to get sigrok-cli?

Sigrok offers two main possibilities of getting the cli. Building from source or downloading the packages. All the steps are well described on their wiki page. For building sigrok-cli have a look at this page, while for downloading the binaries and the distribution packages have a lookhere.

Example:

In the following example ADALM-2000 is connected to an I²C device and we are using a Linux AppImage binary for sigrok-cli. 

  m2kcli digital auto -s sampling_frequency_in=1000000
  m2kcli digital auto -c buffer_size=1000 format=binary | sigrok-cli -i - -I binary:numchannels=16:samplerate=1mhz -P i2c:scl=15:sda=7 -A i2c=address-read:address-write:data-read:data-write
