Test repo for Arduino SRS RGA library.
Library code is in ml-rga directory. Will eventually be broken off into separate repo or subrepo to allow installation in projects.
Intended to provide non-blocking serial control and parsing of RGA serial data. RGA commands are slow; returns take 0.1s to several seconds.
Goal is to use serial reader in a rapidly running loop() to put together reply
packets as they come in. Packet completeness controlled by
number of bytes expected in the response. Signal to start reading is setting packetLength > 0.
Availability of completed packet is signaled by newData == true.
System is still clunky. Need a nice way to handle polling and moving to next command.
Current idea is to separate writes and reads. Writes will check if a write is already in progress or if previous result hasn't been read yet and return 0 without running. Allows including writes in the loop. Reads execute the serial reader and check if newData is available. This could get ugly for a series of sequential actions.
