RE: Configuring SPI MCP3008 - jim321 - 2019-03-24
thank you e-sailing , good to know i just installed a node red mcp3008 node it has that choice in its config.
i'll have a look at that file later.
RE: Configuring SPI MCP3008 - jim321 - 2019-03-29
i found all the parts pieces and breadboard for testing.
i did the change in the file e-sailing posted ..that should be all you need to do.
sudo nano /home/pi/.config/openplotter/read_sensors_d.py
change "spi.open(0,1)" to "spi.open(0,0)". (line 437)
ctrl x y
let me know if that works for you..

i have an arduino with firmata for my sensors.
ads1115 also works for analog "I2C".
i think the MCP3008 "SPI" was fixed in the latest release..
I'm also hope for it. But now I have the next situation (by version 1.2.0):
SPI device is working but we can to see only "raw" data (not real). For example, Ubat has near 750V. Checkbox "convert" doesn't works because "value_0 is not defined". Value setting button is not working also.
Previouse version 1.0.0 works correctly (in this tab).
How to solve this problem?
Please help me.

Can you please check if you have the latest file /home/pi/.config/openplotter/classes/edit_MCP.py?
(It should be this one. https://raw.githubusercontent.com/sailoog/openplotter/beta/classes/edit_MCP.py)
You can easily check if you have it by searching for the line.
