PICAXE and LCD

I have looked over CtCs post regarding similar issues with his LCD, but still can get mine to budge. I was hoping to get some guidance on my issue. The issue being I can't get the LCD to work or interface with my PICAXE. Like Ctc, I am using the serial backpack from SparkFun. Here is my code:

Sharp IR Sensor with PICAXE-40x1 Oddity

I am using both a PICAXE-40x1 and a Sharp IR proximity sensor.

My issue is: when I download my code to the PICAXE chip the program editor throws an error saying "cable unplugged, floating pin, etc." When I pull the ground wire on the sensor, the code will download. Clearly an issue with the sensor or how I have it wired. Per the sensor schematic, I have power, ground and signla all wired in.

Has anyone run into anything similar?

Thanks.

PICAXE C?

Someone once mentioned it is possible to program a PICAXE in C. Is this true? Anyone have any experience with this? This seems odd since I thought all a PICAXE was is a PIC with a BASIC interpreter.

Just curious...

Working with encoders

I just got my BaneBot 36mm encoders(pdf) all hook up and calibrated yet I am not fully sure how to work with the A/B signal lines.

I am trying to solve the issue of not being able to run a straight line, or compensate for mechanical imperfections, etc.

Any help getting started would be huge!

PICAXE-08M Zapped?

I have a PICAXE-08M that I belive is zapped. Not sure how I would have killed it but the program editor will no longer download code to it. When I check the firmware, it see's that it is an 08M, etc. 1) Can I confirm the death of this chip for sure? 2) Is it possible to ressurect the chip?

Worth mentioning, we can eliminate the USB, program, or circuit being the point of failure since my 14M works just fine.

Thanks in advance.

These little 16mm spur gearmotors from BaneBots pack a pretty serious punch for the dollar. They boast a 600+RPM rating at no load with 1500ma. The 3mm shaft when … Read more
