Anyone else's queue seems bugged?

Previously I could queue multiple requests and it would fully complete the first request before moving on to the next. Now it seems to send the request after a few seconds and make one big giant todo list. It then fails at everything.

Just bought this panel with a Siemens Logo for £10 from a car boot sale. Any ideas what it was used for? The date on the PLC screen says 2008 and the Logo looks old. I'll probably end up using it for my own projects but just wondering if anyone knows.

Hi All, I need some advice on if I should move on from Delphi HMIs and how to go about doing that.

I just graduated last year so I’m an empty book at the moment. My company has dozens of systems out in the field running HMIs that were programmed using Embarcadero Delphi by a previous employee. I like the HMIs and the Delphi IDE (RAD Studio) but my colleagues and boss would like to move on. These Delphi HMIs are basically free for us, they run on any PC, no license needed. I’m wondering if I should spend my time learning the ancient language of Delphi or try to develop license-free HMIs in JavaScript, Python or something else?

These Delphi apps usually control the data logging, recipe cre

I'm trying to import/pull a pcb into solidworks but I don't have the PCB Add-in and can't find it anywhere. I have Solidworks PCB working fine and have pushed the PCB out but when I open Solidworks I have no option to pull one in and no PCB Add-In.

Can someone post a simple program using InterruptIn. I can't find a simple program that is easy to understand. I've seen a few ones that use a rising edge button but it appears the interrupt is always active and they also use outdated functions like wait.

Would also appreciate any explanation to the code. Additional Q: how can a beginner learn Mbed with the latest version. Anything I find online is outdated and won't work on the latest version. I've purchased arm courses but they suck. Most of the books I've tried are outdated also. Hard times lol.
