Light-dependent resistance get value probelm

[sebillen]

Hi,
I try to get LDR value by following example on TXTwithPython.pdf page 16-17.
What ever I do, value is always -1, do you have a idea?

[ftrobopy]

Should work now.
This was a bug and has been fixed in version 0.9.11

[sebillen]

I download last version and replace ftrobopy_server on Txt.
now I get errors when I execute script

import ftrobopy
txt = ftrobopy.ftrobopy('192.168.7.2', 65000) # Connected by USB cable
R = txt.resistor(3) # Here input 1 is 1
ohm = 0 # Initialize to non­existing value
while 1: # Start endless loop
txt.updateWait()
newohm = R.value()
if newohm != ohm:
print("Current resistance is {:d} Ohm \r".format(newohm), end='\r')
ohm = newohm
if newohm == 15000:
break

[ftrobopy]

Yes, you are right, there still seems to be a problem with I2C (which is anyhow not really supported yet, but is needed for the Communication with ROBOPro).
I will have a look into that

[sebillen]

Hi,
Have you any news?

[ftrobopy]

I uploaded version 0.9.12 with disabled i2c.
ftrobopy_server should work again, including LDR.

[sebillen]

Thanks, working fine, continue my tests :)
