Functions

func CalcAngle added in v0.5.0 

func CalcAngle(ps time.Time) float64

CalcAngle returns the pulse's place along the ring.

func CalcIntensity added in v0.5.0 

func CalcIntensity(ep *Ms.Endpoint) float64

CalcIntensity returns an intensity float ps = pulse start NB: endpoint.MU is already RLocked by the caller (GetPulseDataD3)

func CalcRing added in v0.5.0 

func CalcRing(ps time.Time) int

CalcRing returns which ring the pulse belongs based on age

func CalcSpeed added in v0.5.0 

func CalcSpeed(ps time.Time, config SpeedConfig) float64

CalcSpeed has the following Base speeds for each ring (degrees per 50ms update) Inner ring completes full rotation in ~18 seconds (360° / 2°/frame * 50ms) Middle ring completes full rotation in ~36 seconds Outer ring completes full rotation in ~72 seconds

func InitMIDIOutput added in v0.17.5 

func InitMIDIOutput(view *View, outputLocation string) error

func StartHarmonyView added in v0.10.7 

func StartHarmonyView(c []Ms.ConfigFile, path string) error

StartHarmonyView is the Terminal UI alongside the Web UI, running on localhost:8090 This is the default view when runTUI from a shell. If there is no TTY, it will not runTUI. The `-headless` flag can be used to runTUI in Web UI only mode, StartHarmonyViewWebOnly The TUI operates with several looping and blocking processes, all handled here.

func StartHarmonyViewWebOnly added in v0.10.7 

func StartHarmonyViewWebOnly(c []Ms.ConfigFile, path string) error

StartHarmonyViewWebOnly is the Web UI only, running on localhost:8090 The ticker for the runtime loop is here as a goroutine, the web server blocks. This runs when using the `-headless` flag. Logs appear in the console instead of a file.
