RF Power Meter 2 (RFPM2) – update 04/21

RF Power Meter 2 is a logging RF power meter based on AD8307 and ESP8266.

The project was used as the basis for a new project, and during that development work some improvements were made and ported back to RFPM2.

Taking heed of ‘official’ advice that SPIFFS has been deprecated on ESP8266 and that LittleFS was a superior replacement, RFPM2 was migrated to LittleFS.

The main enhancement inherited from ltm is that the choice of configuration file is persistent across restarts. The most recently selected configuration file name is stored in the file system in file /mru.txt, and on restart, that file is read to select a configuration file.

Code remains available on github.
