HTML5, PHP and JS communication with serial usb device #21

Open pmfooks opened 7 years ago

pmfooks commented 7 years ago

I have a standard PHP program that uses Javascript running on a Windows 10 Pc. I want to get serial device (Ohaus scale) data and send requests to the scale. I have seen a lot of discussions about various techniques using Python, VB, C++, Arduinos etc. Even using an Excel spreadsheet to communicate with the serial port. There appears to be many ways to communicate with a serial device but all paths I take yield no results. Given my environment what path would you recommend. I don't mind using yet another language if it will yield results. What do you recommend?

hi, in Windows the device mgr shows the status of a serial port offen incl connection parameters (comport + baudrate possibly) with that info try to send/receive bytes with a serial terminal EG. hterm once you See bytes in the terminal Programm let me know Le 12 avr. 2017 6:04 PM, "pmfooks" notifications@github.com a écrit :

Hello again Patrick,

in Windows the device mgr shows the status of a serial port offen incl connection parameters (comport + baudrate possibly)

My device mgr for COM3: [image: Inline image 1] You say:

with that info try to send/receive bytes with a serial terminal EG. hterm once you See bytes in the terminal Programm let me know

but when I put weight on the scale nothing changes in Device Manager. You say with "a serial EG hterm" - what does that mean? Pete

In your article http://thinkingonthinking.com/serial-communication-with-nodejs/ you say

Let’s create a fresh JavaScript project and add this module to it:

$ npm install --save-dev serialport

I am familiar with the command "npm install . . ." but what is "$ npm install" ? Is that Jquery? What module do you mean?
