I have been doing some more testing of voltage reading, this is what I
found
Testing on Pi4 with Sheepwalk RPi3 adapter with 2 voltage sensors, a
DS2437 and a DS2438
Reading voltage from cached takes around 0.06 seconds for each, reading
from uncached takes around 0.28 seconds for DS2437 and 0.23 seconds for
DS2438.
I then tested setting the /simultaneous/voltage bit followed by a 1
second delay
Setting the /simultaneous/voltage bit causes CRC16_errors and
CRC16_tries both to increase by 6, CRC8_errors remains unchanged,
CRC8_tries increases by 2
Setting the /simultaneous/voltage bit has no impact on voltage read
times, so it is not doing what I thought it was supposed to do.
This is on the system that I am also using to test temperature reading,
with no errors, so I am pretty sure the errors are not caused by a
hardware problem.
Thoughts?
