libsigrok now supports the BayLibre ACME device.
This a BeagleBone Black cape with an I²C-attached Texas Instruments INA226 current/power monitor and an I²C-attached TI TMP435 temperature sensor.
The sensors are supported in mainline Linux. The drivers expose a standard interface via the Linux sysfs pseudo file system, which the libsigrok driver uses.
The driver was contributed by Bartosz Golaszewski (of BayLibre), thanks a lot!
Bartosz will also present a Sigrok: Adventures in Integrating a Power-Measurement Device talk at the Embedded Linux Conference on March 24, 2015 (schedule) in San Jose, CA.
