|
|
pijuice - driver for UPS in PiJuice HAT
|
|
|
|
NOTE
|
|
----
|
|
|
|
This man page only documents the hardware-specific features of the
|
|
*pijuice* driver. For information about the core driver, see
|
|
linkman: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.

|
|
Optional: use DIAGNOSTICS to describe troubleshooting techniques that are
|
|
longer than what can be conveniently described in the driver error messages.

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.
