    Default 18f4431 PORT.5 Problem Large automated machine

    I don't post much but last night I was work on finalizing a hserin interrupt routine for a project I'm working on. I'm using pic18f4431 portb.5 as an output for a buzzer on my main board. I normally just hook my scope to a jumper pin for portb.5 to monitor as a heart beat. Anyway I've used this main board in many projects so I know there are no hardware issues. But for some reason after testing the hserin routine portb.5 stopped working. I've tried everything I know, I wrote a simple program just to toggle portb.5 and portb.6. Portb.5 nothing sitting at zero volts portb.6 10ms square wave. I've tried a new chip as well and I can't seem to get this running. I haven't seen this before but the fact that even a new chip won't work leads me to believe some obscure setting is wrong and can't find it. The crazy thing is that I loaded my original code back to the board and portb.5 no longer works. So it has to be a setting of some sort.

    If anyone can help me get this going I'll post a full project and video of a large feed to length automated machine I'm finishing up. Thanks

    I usually use meCONFIG.exe just because it's so much faster when I'm writing code and it has the chips in it I use. Here is the long form of the same file. The weird thing is that this program was working just fine. And playing around with HSERIN with and interrupt routine is what messed things up. I had the interrupt working fine and just change a little bit of code and then it stopped working. I've tried the original code without interrupt that's been working for a month just fine and it won't run portb.5 now. Could something have gotten screwed up with the programming software? I"m using the melabs U2 USB programmer. It's just odd, nothing was hooked to the pin but my scope.

    Yep I tried that as well. My first post shows CONFIG PWM4MX = RD5 The second post I was just showing the output for meConfig one line of code. Still stumped. Tomorrow I'll try another board with a fresh pic, unless there is something setup in the programming software I'm unaware of.

    Plot thickens . I went to my shop today and programmed this simple code to the board and it works fine. I then try and program the same code from my laptop even after uninstalling and reinstalling U2 programming software. Nothing now it won't work. It's got to be some setting that got messed up. I need to be able to program it from my laptop though in the field. Any thoughts?

    Ok I found it, there were a couple of configuration bits that for some reason the config setting I originally had didn't work when I launched the programmer. I changed them with the U2 software before programming and now all is well. I guess this is one of those moments where you've been staring at the screen for hours and you mind is starting to get tunnel vision. Thanks for you help

    Oh yeah as soon as I get the machine done I'll post some pictures and video of the project as well.

    Well I finished up the machine and delivered it. My client is thrilled and has more automated machines he wants me to get started on. But like I said I'd post a little about this project. This machine is for a very progressive framing company that is automating every aspect of their business. This machine will except window and door water proofing seal from 4" to 30" wide and interface with their software over USB. They have an in house software engineer that writes all their custom software to break a job down and minimize waist. Every aspect of their framing is maximized through automation. I worked with him over the internet interfacing my control with his software and after a handful of emails and a couple calls we had it debugged and running. Minus my original post here which was a late night, frustration and a wrong configuration bit. It bites us all at some point. So here is the youtube video of the project in front of my shop.


    Also the main PCB and secondary interface PCB for using the DYN4 AC servo drive and all inputs and outputs. I'm using a pic18f4431 on the main board because it's a handy controller with and easy to use quadrature encoder. It's one of my basic boards I always use designed in diptrace. Here are some pictures.

    Good work!

    I wonder why is it necessary for the roll tape to travel through almost right angles?

    The machine had to be built to take many different types of tape of width and thickness. So for small tape it looks a little silly for the large stuff it really helps to run it though multiple rolls like this for tracking. I've done several other machines similar to this and the more rolls you run though it keeps the material tracking in the center. It's especially important as you can see in the video I have a capacitive proximity sensor that triggers an interrupt that stops the machine saving the position and allowing the operator to splice in a new roll. This company is big on not wasting material. Their custom software breaks down an entire house plan and organizes all the cutting on automated chop saws. They can run all day cutting lumber and making an entire house and maybe loose 1.5 linear foot of wood total. It blew me away to see it. I was contacted over the net by the owner to build a machine that would automate tap cutting and integrate it with their software engineer's software. The owner has all kinds of ideas he wants to automate and has no problem spending money because he makes it up quickly in cost savings. This maybe just the first step to this project as well, next I need to add a line printer to it and possibly design a re-roll machine on the out feed of this one to roll the cut parts back onto a roll. This way his crews can just go window to window and unroll the tape, every thing is labeled and it goes together like Lego's. I love designing these machines from the ground up and building them, and it pays for my shop as I do it on the side.

    Great! Glad you do such things and get paid as well. Well done!
