​The below Python code controls IR ports on a MUSE controller.  It contains code that configures the ports, sends IR commands, and also uses one IR port as a one-way serial device.

MUSE IR Example

from mojo import context
context.log.info('*** Python Script Start ***')
############ Create devices and organize them ###################
idevice = context.devices.get('idevice')
ir1 = idevice.ir[0]
ir2 = idevice.ir[1]
ir3 = idevice.ir[2]
ir4 = idevice.ir[3]
dvTP = context.devices.get('AMX-12345')
irPorts = [ir1, ir2, ir3, ir4]

#################### Configuring IR ports #######################
### Enable Fault Detection on all IR ports
for port in irPorts:
   port.enableFaultDetection()
### Creates function to handle IR fault errors
def handle_ir_faults(event):
   print(f"Received fault from {event.path['data']}: {event.arguments['data']}")
for port in irPorts:
   port.fault.listen(handle_ir_faults)
### Set Port 1 on/off times to 500 milliseconds
ir1.setOnTime(500)
ir1.setOffTime(500)
### Set carrier mode on for Port 2
ir2.carrier.value = True
### Set keypadMode 1 for Pot 3
ir3.keypadMode(1)
### Set IR Port 4 for Serial mode and set communication parameters
ir4.mode.value = "SERIAL"
ir4.setCommParams("9600", 8, 1, "NONE", "232")

######################### IR Functions ##########################
### Pulsing an IR port via channel number
def channelPulse(event):
   ir1.bufferedSendIr(1)
### Pulsing an IR port via function Name
def namePulse(event):
   ir2.bufferedSendNamedIr("PLAY")
### Sending a channel input using the keypad macro
def keypadMacro(event):
   ir3.keypadMacro(325)
### Sending a one-way serial string
def oneWaySerial(event):
   ir4.send("POWR ON")
### Clear and send via channel
def clearSendChannel(event):
   ir1.clearAndSendIr(2)
### Clear and send via name
def clearSendName(event):
   ir2.clearAndSendNamedIr("STOP")
### Continuous via channel (remember to turn this off)
def onIr(event):
   ir1.onIr(16)
### Continuous via name (remember to turn this off)
def onNamedIr(event):
   ir1.onNamedIr(27)
### Turn off IR on the port
def offIr(event):
   ir1.offIr()
### Load IR file via code
def loadIrFile(event):
   ir1.loadIrFile("SamsungE750.irl")
