This is the signal you will run to your touchpanel. Insert an ASCALEL (Analog Scaler with I/O Limits). The final step is to scale the value from it's current range of 0d to 98d, up to 0% to 100% so you can use a gauge on the touchpanel. Ain1 will be "denon_volume_tens_scaled" and ain2 will be "denon_volume_units" Aout will be "denon_volume_decimal" You will now have a decimal value, ranging from 0d to 98d, which provides the volume of the receiver.ħ. The next step is to add the scaled tens to the units. The upper limit of the tens will be 90d, and the upper limit of the units will be 9d.Ħ. The format will be 0d, as the values are all unsigned. The output lower limit of each will be 0d. Both will have the lower limit of 48d (decimal equivalent of 0 in ASCII) and the upper limit of 57d (decimal equivalent of 9 in ASCII). These will be configured to not only convert the values from ASCII to decimal, but also scale up the tens so that 1d = 10d, etc. The first will be for the tens, the second will be for the units. Insert two ASCALELs (Analog Scaler with I/O Limts) into your program. I had originally suggested using a more cumbersome method, but Lindsay made the following great recommendation, so I'm updating the post. Now we need to convert your data from ASCII to Decimal, and scale the tens value up. Name the top one "denon_volume_tens_ascii" and the second one "denon_volume_units_ascii"Ĥ. The two characters you specified with 0200h a>s the maskword will be sent to these analog signals. Highlight the analog output and hit ALT-Plus once to get a second analog signal. This field must be a carriage return, which is 0D in hex. These characters are the volume payload, which you want to extract to use to determine the volume. In the third and fourth fields, put 0200h. (The second character must match V, which is 56 in hex) The "4D" is the hex value of the character the first character must match, which in this case is M (4D hex). The "01" indicates that the character MUST match this character in order for parsing to proceed. This is because the string you are receiving is five characters long. Highlight the parameter field and hit ALT-Plus until you have 5 maskwords showing. You then need to set up your maskwords in the parameter fields.
#Crestron simpl plus serial
Place the denon_gather_rx$ on the serial input. Insert a STOA (Serial to Analog) symbol in your program. The purpose of the GATHER symbol is to collect all of the traffic from the receiver, waiting until it sees the CR (which is Carriage Return = 0D hex)ģ. The length parameter should be longer than the longest string you'd expect to get from the receiver. Place a new signal, denon_gather_rx$, on the out$. Place the denon_rx$ signal on the in$ of the GATHER. On the COM port rx$ port, put a signal denon_rx$Ģ.Insert a GATHER (Serial Gather) symbol in your program. Here is some basic guidance on how you would parse this for display on a touchpanel (on a full-range (0% - 100%) gauge):ġ. "80" is the volume in ASCII, ranging from 00 to 98. The protocol states that when the master volume changes, you will be sent the following string: The document used as a reference is " AVR-3805_SerialProtocolv4-0UpdCV_serialprotocol.pdf" I don't have this device in front of me, so none of this is tested. The example is a Denon AVR-3805 receiver.
#Crestron simpl plus windows
A brief tutorial on parsing serial response strings for volume, using only SIMPL Windows (no SIMPL+). I'm replying here so I can use images, unlike in the text-email-only forum. The first question is one that was actually asked by cwbowen2000 on the Crestron Yahoo! group. I encourage criticism and suggestions about the techniques I present, or questions about examples you'd like to see. I'm starting this blog as a forum for posting examples of Crestron SIMPL Windows programming techniques, as well as other Crestron discussions.
