Trying to get serial access to the controller on LS-WXL

[eugrus]

eugrus@LS-WXL:~/Python_buffalo_libmicon$ sudo ./get_micon_version.py 
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 398, in _reconfigure_port
    orig_attr = termios.tcgetattr(self.fd)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^
termios.error: (5, 'Input/output error')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/eugrus/Python_buffalo_libmicon/./get_micon_version.py", line 5, in <module>
    test = libmicon.micon_api("/dev/ttyS1")
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/eugrus/Python_buffalo_libmicon/libmicon.py", line 179, in __init__
    self.port = serial.Serial(serial_port, 38400, serial.EIGHTBITS, serial.PARITY_EVEN,
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/serial/serialutil.py", line 244, in __init__
    self.open()
  File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 332, in open
    self._reconfigure_port(force_update=True)
  File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 401, in _reconfigure_port
    raise SerialException("Could not configure port: {}".format(msg))
serial.serialutil.SerialException: Could not configure port: (5, 'Input/output error')

I've then replaced

test = libmicon.micon_api("/dev/ttyS1")

with

test = libmicon.micon_api("/dev/ttyS0")

Here's what I'm getting now:

sorry, was thinking about the "TS-WXL".

If I remember correctly that SoC has no temperature sensor. One option would be to use the "drivetemp" module which lets you use the SMART temperature of the drives as a sensor.

Thanks for getting back to it!

What would be the best way to just statically slow down the fan?

[1000001101000]

I don't have one online to check right now, but the gpio-fan driver takes the two GPIO pins that combine to provide 4 fans speeds off/low/med/high and provide a fake PWM interface for them.

You can probably set the value manually with something equivalent to echo 128 > /sys/class/hwmon/hwmon1/pwm1

Thanks! echo 100 > /sys/class/hwmon/hwmon0/pwm1 does it.
