in your pin_mapping.json, add a powermeter object like this:
[
{
"name": "My Board",
...
"powermeter": {
"rx": <num>,
"tx": <num>,
"dere": <num>
},
...
}
]
the SML power meter requires the rx pin to be set. the SDM power meter
requires the rx and tx pins are set. the "dere" pin pin is optional and
if set, this pin controls the driver enable and receiver enable pins of
the RS485 transceiver. the SDM library handles this pin.
closes #771.
