Note

Two NUT websites
This version of the page reflects NUT release v2.8.1 with codebase commited 4ba352d8f at 2023-10-31T21:46:20+01:00 Options, features and capabilities in current development (and future releases) are detailed on the main site and may differ from ones described here. |
NOTE
This man page only documents the hardware-specific features of the pijuice driver. For information about the core driver, see nutupsdrv(8).
Note
|
This manual page was hastily adapted from related asem driver
manpage based on information from the original pull request, and so
may not fully apply to PiJuice HAT, patches from experts are welcome. |
SUPPORTED HARDWARE
The pijuice driver supports the portable PiJuice HAT UPS for Raspberry Pi embedded PCs.
EXTRA ARGUMENTS
The required parameter for this driver is the I2C bus name:
- port=dev-node
-
On the PiJuice HAT, this should be
/dev/i2c-1
.
INSTALLATION
Note
|
This section was copied from asem driver manpage and may not fully
apply to PiJuice HAT, patches are welcome. |
This driver is specific to the Linux I2C API, and requires the lm_sensors libi2c-dev or its equivalent to compile.
Beware that the SystemIO memory used by the I2C controller is reserved by ACPI.
If only a native I2C driver (e.g. i2c_i801, as of 3.5.X Linux kernels) is
available, then you’ll need to relax the ACPI resources check. For example, you
can boot with the acpi_enforce_resources=lax
option.
KNOWN ISSUES AND BUGS
Note
|
This section was copied from asem driver manpage and may not fully
apply to PiJuice HAT, patches are welcome. |
The driver shutdown function is not implemented, so other arrangements must be made to turn off the UPS.
