Signals

Overview

The Signals section of the cee API provides functions for driving, measuring, and managing electrical signal pins (voltage, current, resistance, frequency, and phase) in CC: Computer Energetics.

Calling Conventions / Prefixes

All methods within the Signals section are accessed through the global cee namespace:

local volts = cee.getSignalVoltage(1)
cee.setSignalVoltage(1, 50)

API Reference Table

Method Signature	Arguments & Types	Description
`cee.getSignalVoltage(pin)`	`pin` (number)	Returns volts on the pin.
`cee.setSignalVoltage(pin, v)`	`pin` (number), `v` (number)	Drive the pin, 0-100V, 20A max.
`cee.getSignalCurrent(pin)`	`pin` (number)	Returns amps through the pin.
`cee.setSignalCurrent(pin, a)`	`pin` (number), `a` (number)	Drive it as a current source.
`cee.getSignalResistance(pin)`	`pin` (number)	Returns ohms looking out of the pin.
`cee.getSignalRMS(pin)`	`pin` (number)	Returns RMS volts over the last second.
`cee.getSignalFrequency(pin)`	`pin` (number)	Returns Hz, 0 if not oscillating.
`cee.getSignalPhase(pin)`	`pin` (number)	Returns degrees against the sample clock.
`cee.getPhaseAngle(a, b)`	`a` (number), `b` (number)	Returns degrees between two pins.
`cee.isDriving(pin)`	`pin` (number)	Returns whether we are driving this pin.
`cee.clearSignal(pin)`	`pin` (number)	Stops driving the pin.

Lua Code Examples

Example 1: Measuring Voltage and Current

local pin = 1
local volts = cee.getSignalVoltage(pin)
local amps = cee.getSignalCurrent(pin)

print("Pin " .. pin .. " -> " .. volts .. "V, " .. amps .. "A")

Example 2: Driving a Signal Pin

local pin = 2
-- Drive pin 2 at 50 volts
cee.setSignalVoltage(pin, 50)

-- Check if we are driving it
if cee.isDriving(pin) then
    print("Pin is being driven.")
end

-- Stop driving later
cee.clearSignal(pin)
