Subject: [PATCH v5 0/9] w1: ds2438: adding support for calibration of current measurements
Date: Fri, 9 Apr 2021 00:09:36 -0300 [thread overview]
Message-ID: <20210409030942.441830-1-sampaio.ime@gmail.com> (raw)
In-Reply-To: <20210405105009.420924-1-sampaio.ime@gmail.com>
The following patches aim to make a user able to calibrate the current
measurement of the DS2438. This chip uses a offset register in page1, which
is added to the current register to give the user the current measurement.
If this value is wrong, the user will get an offset current value, even if
the current is zero, for instance. This patch gives support for reading the
page1 registers (including the offset register) and for writing to the
offset register. The DS2438 datasheet shows a calibration routine, and with
this patch, the user can do this quickly by writing the correct value to
the offset register. This patch was tested on real hardware using a power
supply and an electronic load.
Please help to review this series of patches.
Best regards!
Sampaio
