Protocol

ACME probes are connected to I²C bus #1 of the BeagleBone Black via the ACME cape.

The components used to do actual measurements (INA226 & TMP435) are supported in mainline Linux. The drivers expose a standard interface via the Linux sysfs pseudo file system.

The ACME driver for libsigrok uses said interface to acquire measurement samples and control the cape (change shunt resistance configuration, power-off measured devices etc.).
