    I'm a little more wide awake today and can think clearly. As mentioned, address those coding issues referenced in the error file above, but that's not what's causing your problem. It works fine in a chip here, aside from the small bug relating to the "Arm" LED. Changing the code layout to how...

    What component to use to keep multiple pins high

    What Bob said. Consider a 74HC595 maybe.

    You answered your own question, as Alec said. Your question - "what can i do if my service provider has bad options?" Change sevice providers. Or change plans with your existing service provider.

    ET-Robot 877 PSPI cable diagram

    Nobody here is very likely to be able to help you directly with cable details for the ET Robot car. It's a purely Malaysian kit, and the manual is only produced in Malaysian. However, a little searching tells me that WINPIC800 software is compatible with the "Tait" style PIC programmers...

    Building an Atari 2600

    The fun's definitely in the building. I have heaps of things here that I could have bought cheaply, but preferred to make. I considered suggesting removing the pots from the joystick and fitting switches directly earlier. That could be a good project, but the 2600 is bound to lead to...

    Help with open collector output

    Yes, but if it's an open-drain output, the drain will be pulled to 0V when the 3.3V / 5V is applied to it's gate, so measuring between the drain, (output), and the +9V supply terminal should result in a reading of ~9V. I thought that was a MOSFET package in the fine yellow-lined area. That was...

    DALI lighting interface

    First, you're correct about the transmitter. It causes a short across the transmission lines for a "1". When a "1" is being transmitted, the transmitter's 'short' across the lines causes more current to flow. >=60mA, to be exact. That current develops a voltage across R2 in the receiver, the...

    Building an Atari 2600

    No offense, but I think you're biting off more than you can chew, after seeing your other thread earlier. You should start out with more simple projects until you learn a little more about basic electronics, then work up to a project like this. It's not really a beginner project.

    And one very last thing, here's the error file from the build. It reminded me that all instructions should not have been indented differently. Follow the directions in the error file. I'd forgotten that, and just copied the layout of your's. Check the two messages numbered 302, as well...

    Turn LVP off! Just use my line, OK.

    And one last thing - ensure that you're using the right linker script, and that you have the correct device selected in the MPLAB IDE and in your programmer. And that the fuse settings are right in your programmer software, just in case it's overriding the config line. Gotta go. Good luck.

    Your schematic? I don't have it. I only have the one I drew up based on your code. I didn't get the expected email from you with the schematic and the source code. That's why I had to do it the hard way. I'm very tired now, it's 11:15pm here, and I've spent more than enough time on this tonight...

    And before I pull it apart to re-use the breadboard, here's my breadboard circuit,. The green wire is the reed switch and the red wire is the "Arm" switch. (I didn't worry about real switches.):-

    You don't need to email the source code now. I copied it from your screenshot in post#9. I realised that I don't have a 16F628A, so I had to use a 16F628. Virtually the same. I altered your code accordingly:- LIST P=16F628 #include "P16F628.INC" and used the "16f628.lkr" linker script. It...

    I'll only need the build command if there's anything non-standard, I just realised. The MPLAB IDE defaults should be OK otherwise. I've set up an MPLAB project, with the linker script selected. All that's needed now is the source file and it's good-to-go. (If you succeed in emailing it.)

    If you can manage to upload it, I can run it in a chip tomorrow and see if I can duplicate the problem. Maybe I missed something, I'm pretty rusty with assembly, but it looked fine to me when I went over it. Is it only a problem with uploading to this site? I could PM you my email address to...

    I need help locating something to measure current on a circuit and relay that via bluetooth.

    I thought he wanted to measure current change over time, store the results, then transmit periodically, but re-reading the original post, I think he wants to stream it as you suggest Harald. That's a little easier - one less part. It'll flood the phone with data though.
