Hi @tomasfichetti Is this still an issue? Sorry for the long delay here...
Hello, Getting the same issue. Can you help me out.. I am using OPC-R1.
ERROR:opc:Could not parse the fimrware version from 1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó1ó Traceback (most recent call last): File "/home/pi/py-opcr1/opc/init.py", line 77, in init self.firmware['version'] = int(re.findall("\d{3}", infostring)[-1]) IndexError: list index out of range
Your firmware version could not be automatically detected. This is usually caused by bad wiring or a poor power supply. If niether of these are likely candidates, please open an issue on the GitHub repository at https://github.com/dhhagan/py-opc/issues/new. Another option would be to
increase the max_cnxn_retries variable if you feel the serial communication is being held up for some reason.
Hi @dwitam can you post the code you're using? There currently isn't support for the OPC-R1 or OPC-N3 in the master branch as they're completely different. There is a development branch that supports (hopefully) these sensors, but it hasn't been tested.
`import spidev import opc import time
spi = spidev.SpiDev() spi.open(0,0)
spi.mode=1 spi.max_speed_hz= 500000
try: alpha=opc.OPCR1(spi)
except Exception as e: print(e)
alpha.on() time.sleep(1)
print("<---------Reading Firmware version-------------->") print(alpha.read_firmware())
print("Read info string") print(alpha.read_info_string())
print("Read serial number") print(alpha.sn())
print("Read Histogram") print(alpha.histogram())
time.sleep(10)
print("Read PM") print(alpha.pm()) print("Pinging From RPI") print(alpha.ping())
alpha.off() `
Hello! I'm having problems with opc-n2. I already check the cables and the power. I also update the library.
This is my program:
Turn the opc ON
Read the information string
The return is:
