Re: A4988 control velocity Stepper

Hi I still think this is part of a bigger picture as I don't see any initialisation of the MCP2307 IO expander, nor any calls to it. Where is your stepper motor connected to? Difficult to say what is going wrong as without an explanation of what it should be doing I would need to reverse engineer to...

Re: CORS error

Hi Steve As I often say, I'm not a programmer I'm a Flowcoder, which is testament to how good your product is. My last play with anything java was a while back, probably aided by (in my opinion) one of the very good "Easy Steps" books by Mike McGrath. Got enough info to do what I needed. A...

Re: A4988 control velocity Stepper

Hi I have had a brief look at your chart and tried to figure things out. I don't see any call at all to your Timer Macro. This looks like a snippet of code from a larger chart. Can you tell us what it is you are trying to achieve and how? I'm guessing that you are trying to measure the speed of a mo...

Re: CORS error

Hi Steve The best success I have had is to upload the generated file to a website and access it from your phone from there. Not sure I understand what you mean by that. Restating I'm in no way a HTML guru so the following is little more than stabs in the dark :lol: Using FF with web developer tools ...

Re: CORS error

Hi Strange.... I get the CORS error perhaps six times out of ten. Really unsure about that. Although I do get the data returned in a browser, I can't seem to get the macro to call. The HTTP Fetch component is supposed to call a particular macro but it never seems to get called. I even changed the ma...

Re: ESP Quarantine

Hi So it's a sort of charity raffle then? Guess that's a good ploy to get people in as the places seem very busy on those nights. Ton vs tonne is as far as I am aware exactly as you suggest, imperial vs metric. I am of an age where they are interchangeable, understanding both systems. Years ago they...

Re: CORS error

Hmm... Opening up Firefox again and connecting to the forum, I noticed the Cross-Site icon in the tab. Killing that, which I presume was a tracking cookie of sorts, I tried my web-chart again, with FF dev tools open.. This time I connected without issue and got my JSON string returned, no mention of...

Re: CORS error

Hi It seems that I need to add a header in the server to "Allow Origin" to get rid of the CORS error. However if it was a server issue, why does it work on any browser if I type in the URL directly or use an embedded device, but not if I create a Web Developer chart. Guessing it is somethi...

CORS error

Hi I'm in no way an expert in HTML so hopefully someone in the forum can assist. Being bored, and with no hardware I'm limited to simulation. There is a website I use and I created a chart running on a RPi that sends a GET request and after receiving the JSON reply, gives me the pairs of interest. T...

Re: ESP Quarantine

Hi

Looking forward to some warmth. Been wet the last couple of weeks and at night, even with the aircon off I'm wearing a jumper. Very humid though, I'm drenched by the time I've walked a few hundred metres.

What's with the Friday night "win a ton of meat" at the pubs?

Regards
