    Simulator user guide

    Obviously I'm not looking hard enough because I can't find a user guide or help for the simulator. I would be grateful if someone could point me in the right direction.

    Download pin

    Is it acceptable/safe to disable the download input pin by connecting it directly to earth rather than through a resistor? The reason for doing this is to minimise component count. The chip will be programmed out of circuit and the code will have been debugged beforehand.

    Interrupt availability

    Simple question to which I can't find a definitive answer in the manuals: are PICAXE interrupts available on 18X and 18M2, and if so, on which pins? All of Port C presumably? Thanks

    Use of SETINT

    I am attempting to protect code in the main body of my program from interference from interrupts by using SETINT OFF-SETINT (on) around the critical section. This appears to cause a lock-up in the interrupt system which I am having difficulty diagnosing. Is this an acceptable use of SETINT...

    PE Hangup

    Never seen this one before. After a month or so layoff I have been trying to download the embryo of a new piece of PICAXE software. No download progress box displayed and the PE hung up with a "Not responding" flagged in the window title bar. The only way out was to restart the machine. I...

    Servo documentation

    Hi. I'm having my first attempt at controlling a servo from an 08M2. I understand the correct approach is to issue an initial servo command to initialise and then perform subsequent positioning with servopos. Manual 2 tells me that servo only works on port B on M2 parts. Manual 1 tells me...

    Enabling internal pullups

    Hi forum. I have been trying to enable the internal pullups on a 14M without success so far. I read the PIC data sheet which references the COMCON0, ANSEL, TRISA and WPUA registers in connection with WPU control. I wrote a simple test program to initialise these registers but it failed to...
