Hi,

Unfortunately I am getting a syntax error. Also will this combine the high and low bytes?


pi@RevPi17663:~ $ python3 test.py
File "test.py", line 15
print(f"value={rpi.io.heater.value}")
^
SyntaxError: invalid syntax





import revpimodio2
import time
import struct

rpi = revpimodio2 ...

Thanks for replying. I could not find any documentation about read_procimg.
I tried with autorefresh and sometimes when I re-run the script, I get zero instead of the correct number. However piTest -r HEATER_V_HB always gives the correct number.

Is there anything I should do to remove the warnings ...

I tried revpimodio2, but it didn't work. I will eventually want to use a variable name from the vars list.

See the errors and warnings.


import revpimodio2
import time

rpi = revpimodio2.RevPiModIO()

vars = {
b"HEATER_V" : "MBFLOAT",
b"HEATER_I" : "MBFLOAT",
b"HEATER_P" : "MBFLOAT",
b"FAN_V ...

I tried to fix the length to 8 in which is the same value I got from piTest, but I still got an erroneous value returned. I also tried to use the .decode() function from here https://kunbus-gmbh.atlassian.net/servicedesk/customer/portal/1/article/438108161. But it did not work.

This is the output ...

I printed out the offset, bit and length. It looks like the length is the one that is incorrect.
So it is this line of code that is bad. Do you know what it should be?
length = int(struct.unpack_from('>H',ret,35)[0]/8)



pi@RevPi17663:~ $ python3 get_data.py
var name: b'RPI_TEMP' , type: SYSINT ...

This is the contents of config.rsc. I have trimmed the unused bits to fit in the message limits of the website.

Hi,

The IOs are being read using an old method, similar to this tutorial: https://www.youtube.com/watch?v=cz163tcQCsM
After doing an apt-get upgrade, the IOs cannot be read using this method. Is there an easy way to make the old method to work to maintain compatibility as I did not design this ...
