One of the local middle schools that uses my robotics kit based on the PICAXE 14M (www.erlrobotics.com) is getting a memory verification failed error. [Please see the attached pdf file for the testing setup details.] I've evaluated both the computing environment and the PICAXE circuits which...

First, my thanks to the PICAXE team for the M2 chips. Looking forward to replacing the 14M with the 14M2 in my high school robotics kits. My question... could someone please clarify for me the maximum number of pwmout and servo commands that can be used with the 14M2? I'm trying to...

First (as always), thanks so much for the great PICAXE system. My problem... I'm not able to get patch 5.3.4 to install on my Win 7 (64bit) system or my laptop running Win XP (SP#). The full version v5.3.3 is installed and works normally. When the v5.3.4 upgrade patch exe is run, the main...

I'm hoping someone can tell me if the PICAXE-14M would be potentially damaged / erased if located next to a rare earth magnet? I use the PICAXE in a small classroom robotics kit and want to place small rare earth magnets in several places on the robot including the chassis and gripper. For...

First... many thanks once again to this great forum. My first pilot introductory engineering course went well this last school year and I'm now introducing the PICAXE to a number of additional local schools. My question... I'm hoping someone can tell me if / how I can get permission to...

I'd like to use a momentary On switch to start a program plus stop the program at any time during the program execution. I'd then like to be able to re-start the program at the beginning by again pressing the switch. I really thought this functionality would be easy to implement using the...

Does the flowcharting tool have a way to add a label in the flowchart that is converted to the same label in the BASIC program? Looking at the samples plus my own attempts to create a flowchart, seems the flowchart "label" tool is only useful in the flowchart diagram, ie, the labels don't show...

I'm hoping someone can tell me where I can get a copy of the Microchip PIC12F684 datasheet. We are using the PICAXE-14M for a high school robotics course and I'd like to have a copy of the Microchip PIC datasheet for reference, but I can't seem to locate one. I located a chip comparison matrix...

I've been attempting with no success to get pwmout command to work with a 14M (firmware 9.C). I'm trying to setup a simple program for a high school robotics program, and didn't realize this command was going to give me such a problem. Suspect it's another newbie mistake or two. So, I'm hoping...

Could someone please explain to me how the PICAXE serial interface to the PC is accomplished using the 2 resistors but a PIC microcontroller requires a special driver/receiver chip comparable to the MAX232? Given the PICAXE is simply a PIC + bootloader, does the bootloader provide this...

Here's another newbie question. I'm starting a new after-school high school robotics program and hoping someone can tell me what I'm doing wrong with this simple program. We want to drive a small bipolar stepper motor using a design + code located online at www.picaxe.orcon.net.nz/stepdemo.jpg...
