Re: Parsing a string

#1438

Mike

I like the method Dave used in his DLI Relay Flow. ?The response is an eight-digit number, with 0 or 1 in each digit, depending on the relay status. ? Dave has a function to do a "logical and" for each digit to determine and outputs a true or false. ?Would this work for you? ? For example, if the second digit is 1, then the function "1 & 2" is true, because the binary of the second digit is 2**1 = 2 and 2 logical 2 is true. ?Likewise, for the third digit, 2**2 is 4 so the logical comparator is 4.

Alan. WA9WUD

And here is the function. ?Of course,var onmsg = { payload: msg.payload,topic:msg.topic };

var offmsg = { payload: msg.payload,topic:msg.topic };

=========================

?

var msg1 = { payload: msg.payload,topic:msg.topic };

var msg2 = { payload: msg.payload,topic:msg.topic };

var msg3 = { payload: msg.payload,topic:msg.topic };

var msg4 = { payload: msg.payload,topic:msg.topic };

var msg5 = { payload: msg.payload,topic:msg.topic };

var msg6 = { payload: msg.payload,topic:msg.topic };

var msg7 = { payload: msg.payload,topic:msg.topic };

var msg8 = { payload: msg.payload,topic:msg.topic };

?

//msg.payload=true;

onmsg.payload=true;

offmsg.payload=false;

?

if (msg.payload & ? 1) msg1.payload=true; else msg1.payload=false;

if (msg.payload & ? 2) msg2.payload=true; else msg2.payload=false;

if (msg.payload & ? 4) msg3.payload=true; else msg3.payload=false;

if (msg.payload & ? 8) msg4.payload=true; else msg4.payload=false;

if (msg.payload & ?16) msg5.payload=true; else msg5.payload=false;

if (msg.payload & ?32) msg6.payload=true; else msg6.payload=false;

if (msg.payload & ?64) msg7.payload=true; else msg7.payload=false;

if (msg.payload & 128) msg8.payload=true; else msg8.payload=false;

?

return [msg1,msg2,msg3,msg4,msg5,msg6,msg7,msg8];?you can download everything form the files section.

Here you go...I cleaned it up...? edit...apparently not enough....try this...I used an inject of 10101010

var output = msg.payload.split("");

msg.out0 = parseInt(output[0]);

msg.out1 = parseInt(output[1]);

msg.out2 = parseInt(output[2]);

msg.out3 = parseInt(output[3]);

msg.out4 = parseInt(output[4]);

msg.out5 = parseInt(output[5]);

msg.out6 = parseInt(output[6]);

msg.out7 = parseInt(output[7]);

?

if (msg.out0 === 1){

msg1 = {topic: 'relay1',payload:'true'};

} else?

msg1 = {topic: 'relay1',payload:'false'};

?

if (msg.out1 === 1){

msg2 = {topic: 'relay2',payload:'true'};

} else

msg2 = {topic: 'relay2',payload:'false'};

?

if (msg.out2 === 1) {

msg3 = {topic: 'relay3',payload:'true'};

} else

msg3 = {topic: 'relay3',payload:'false'};

?

if (msg.out3 === 1) {

msg4 = {topic: 'relay4',payload:'true'};

} else

msg4 = {topic: 'relay4',payload:'false'};

?

if (msg.out4 === 1) {

msg5 = {topic: 'relay5',payload:'true'};? ??

} else

msg5 = {topic: 'relay5',payload:'false'};

if (msg.out5 === 1) {

msg6 = {topic: 'relay6',payload:'true'};

BTW, this can all be done in one function node using Mick’s example then looking for each msg.out to either be 0 or 1 and setting msg.out to false or true. (if/else)

?

More than one way to get to the desired output.

Here is a function to split the input and output a msg for each bit.? ?I used a string of 10000000 as the inject

The output gives you the msg.payload and msg.topic

Here is the function.

You could then run this into a switch node for further?processing or just modify it by creating a var instead of msg and then process it in the function.?

Mick has an extra msg.out. Only need 0 – 7.

?

Here’s a flow using split/switch/function to give false (0) or true (1) for each bit. First bit is top function node and last bit is bottom. Then feed into GPIO node.

Re: Getting started with Node Red

Thanks for the feedback Fred.

?

I have to admit, I do not know JS. Everything I have done in Node Red I have been able to figure out or learn from Google searches and loading example flows from different sites I found using Google.

?

It is really a 3 step process in creating a flow:

Getting the data into Node Red
Manipulating the data into format for viewing
Laying out the dashboard to display data

?

There are tutorials on using the Raspberry OS via telnet (terminal) and/or VNC or local desktop to Pi (monitor keyboard and mouse connected to Pi). I’ll try to ferret out a good video and provide a link.

?

I think the next Zoom session we could work on building a couple of flows. One for getting and sending info to a device and another for controlling simple relays. I actually saw a video online the other day where the author used 3 relays to create a traffic light system. It was very good in explaining how to wire things up.

Subject: Re: [nodered-hamradio] Getting started with Node Red

?

Alan, Dave ... thanks for the Zoom meeting last night. I appreciate your taking the time to host that.?
I have a very extensive? multi-state remote radio system in place and have been remoting since the 1990's. As automated as I am, I often have to bring up multiple systems. There is an appealing elegance to the Node Red dashboards I'd seen.? I was attracted to Node-Red for the control simplicity it offered.

I had a steep learning curve over the past few days to get where I am on Node-Red. I have done a lot of work with Arduino and C++, but I've never played with an OS, the RPi or JavaScript. In future lessons, you might help others along by realizing that there are really 4 steps to mastering this for someone like me (an RF engineer):

1. Learn how to run the Rasberry Pi itself. How to interface to a terminal, etc.?
2. How to load and run the OS.?
3. Learn how to load simple flows in Node-Red using GPIO interfaces.?
4. Learn programming in JavaScript and building the dashboard.

Most Node-Red "beginner" tutorials assume you already know steps 1,2, and 4. That was not the case for me. I felt there was a lack of mid-level tutorials out there. For example, I could find little about how to build and arrange a dashboard. Your meeting last night filled that gap and got me heading in the right direction.?

That said, sometimes the only way to drink from a fire hose is to start drinking.

Thanks for making yourselves available to true beginners and for your patience.?
