Roomba iRobot530 + Berry

[techman83]

So I wanted to play around with Berry Script and also needed a driver for an old Roomba I had laying around, plus a bunch of the Wireless Tag WT32C3-01N ESP32s. After poking around and a bit of a read of the SCI doco, I could get it to talk. Now technically the serial is out of spec (5v vs 3.3v), but it works pretty reliably. If it dies, I'll probably build a custom board with a voltage divider a built-in buck reg.

Driver is here: https://gist.github.com/techman83/45ed4f6de5ff4df0a2de036e33aab0f1

Seems to do what it says on the tin:

"iRobot530":{"State":"3","BatteryVoltage":"16838","ChargeDischarge":"55","Temperature":"33","Battery":"1618"},"TempUnit":"C"}

Obligatory pictures!

Driver definitely could use some polish, but I can command a clean, force dock seeking, and get the stats out of it reliably.
