adding labels for any other stats and settings of interest

[Jipsey-A]

Hi @winginitau , Please could you explain how to do this? I would like to 'look at' VPV. I'm hoping to use an Arduino to read the VPV reading from MPPT, then to use this to vary the speed of a small motor - creating an artwork that encourages interaction with a solar panel to see how it affects the voltage generated. I'm fairly new to this. I tried adding VPV in to the .h file where I could see voltage etc, using similar format, but that doesn't appear to have worked. Thank you!

This is my amended VEDirect.h

• Class / enums / API

Updates:

• 2019-07-14:
  • Rewrite of read - cleaner.
  • Target labels extendible with enum and PROGMEM strings
  • Retired copy_raw_to_serial0() code - use VE_DUMP on read
  • Added some tunable parameters see #defines
• 2020-04-10:
  • Convert to SoftwareSerial so ESP8266 can use native usb serial for debug ******************************************************************/
