I have made some great progress today with the Flex3000 flow. I solved the problem of the built-in TCP server in PowerSDR not accepting multiple connections, with a program I found called Com by TCP. I run it on the host PC that runs PSDR, and add that COM port as a CAT port in PSDR. It's working well, and I can "connect" payloads from different command buttons and switches, and it responds perfectly.

I hit a roadblock with sliders. The slider node outputs a number, but the command requires a 3-digit number, including leading zeros. I tried making a function node with? "msg.payload = parseInt(msg.payload (0,3))"? but that didn't work.?

I know it's just my ignorance in syntax. So......how to you add leading zeros to a payload that doesn't have them?

thanks,

It didn't like that......

Look at the "String" Node, "PadLeft" Method. ?You can specify the number of characters and what to use to "fill" the empty space. ?Here is an example with six digits, fill left with "0".

Understand, I think....

The string node, pad method will keep the number of characters the same and adjust with the "fill character" to adjust the empty space.? Here are two examples, 50, and 14074.? In each case, the total number of characters out remains as specified, six in this example.

The issue is he may need 0, 1, or two leading zeroes thus the if else statement is probably best solution.?

Sent from my waxed string and tin cans.?

Oh no.....somebody stop me....hi hi....I found a way to import the panadapter to the dashboard !!

Wonder how much bandwidth that takes. But it's working pretty well. It's only display, not for input.

// From StackExchange - Function to pad with leading zeros

function pad(n, width, z) {

? ? z = z || '0';

? ? n = n + '';

? ? return n.length >= width ? n : new Array(width - n.length + 1 ).join(z) + n;

}

Examples:

pad(10, 4);      // 0010
pad(9, 4);       // 0009
pad(123, 4);     // 0123

pad(10, 4, '-'); // --10
