I have am MCP3008 connected via I2C to my Raspberry Pi. As i have a different power Supply for this i connected everything to 5V. Well your Software is really great but i found out that the Voltage was shown false with 3.3 Volt maximum. I found out that this was hard coded in your Code. It would be cool if we could set this reference Voltage in the mail config file.

You right, I've kept this feature to later need. But you can use analogReadFloat instead of analogReadVolt. Simply multiply analogReadFloat with real VREF to get a voltage value. analogReadFloat is binded to REST API and Javascript lib too.

You forgot to update the MCP4921 and
MCP4922 subclasses in that file. See
