Hi. I have a serial input node and are reading data from a device. Its a binary input and i split the data in the serials node on eight characters. I get the following data from the serial input: 4/5/2021, 1:57:03 PM node: 1e6025fa.f87f7a msg.payload : buffer[8] [ 1, 1, 1, 1, 0, 0, 0, 0 ] etc I t…

[image] Steve-Mcl: Is that direct from serial port? You didint answer. Can you show your flow?

yes thats direct from serial port

From bitreloader i get the actual value but are unable to switch it seperate nodes so the i can convert and display it [image]

Can you disconnect everything (except 1 debug) from the serial input node and capture data from serial port one more time please (I have some doubts)

serial port and debug only [image]

That is most odd (and very very wasteful) use of bytes. What is transmitting this data? Are you in control of the format of data being sent?

It comes from an engine management system. I want to use the data to make myself a dashboard display. The following is what i have on the data: Ver 3.5 Protocol Real time values You need to poll each block of data by sending a 252 value on the serial port. After the block is returned, an end code …

ok, well that is nothing like the data samples you have sent. i would expect to see something like [23,128,128,250,63,63, ..., ..., etc] The fact you are getting [0,0,0,0,0,1,1,1] and attempting to convert that to 7 is the reason i am confused. If this [0,0,0,0,0,1,1,1] was once more "made up by y…

Byte13 – End Code 252 is the end code

Apologies for he delay. For some reason I can only send 4 messages a day. The "serial port and debug only" data that i send is the real data from the serial input. If I change the serial port to ascii I only get questions marks as an output? The serial port outputs the data really fast so it is dif…

Hi Steve. I have managed to get the serial input data sorted. You were right

Now i must just sort out the buffer parser.

Again many thanks.
