Hi Guys, I know there are going to be some motor experts out there (I'm not by any means) and I would be grateful if you would take a look at the attached picture and let me know if it looks OK or if there is a problem / potential problem. This is a brand new replacement from the supplier and I...

Hi, I get the above in the error log when I simulate my design. The circuit is based on a 14M chip. Does this indicate a software problem or is it likely to be an error in my schematic? I should point out that I'm very much a novice and have only just purchased the VSM software. However, this...

Hi Guys, Thanks to your help my school buggy project is now complete. Well, the prototype is anyway - the kids have still got to finish theirs. It is set up like a car - a motor drives two wheels at the back and a servo steers two wheels at the front. It uses a 14M and HPWM to control the drive...

Dear All, Have rapidly moved on from PWMOUT to HPWM ( in full-bridge mode) to get forward & back as well as speed control. This simplifies the electronics in my H-bridge considerably (only 4 transistors instead of 8). I am using PNP darlingtons as the "top" transistors (A & C) and NPNs as the...

Hi, I need to control the speed of a motor and modified some of Peter Anderson's code to test my H-bridge circuit. The code runs fine on an 08M chip but when I transfer it to a 14M chip there is no output. As far as i can see they are both supposed to use pin2 as the output and that's how I've...
