Please keep this going! I will be back after a long hiatus. The wealth of knowledge here has always solved my problems. I'm not throwing out my old PICs and want to be able to have access.
...

Quite a while ago I wrote something similar. A Visual Basic program running on a PC that communicated with a PIC through the serial port. Visual Basic will let you fashion a GUI with buttons etc to...

I was able to install PBP (v2.50B) in MPLAB (v8.10), but with some annoyances.

I am using a 16F88 chip and in MicroCode Studio I modified the default configuration bits using the @ device ........

I have an OLIMEX ICD-2 that I used with MPLAB to program dsPICs. Is it possible to have MicroCode Studio recognize it as well?

I went to View/Compile and Program options.../Programmer/Add New...

The ESC should work fine for both PIC and steering servo power. I would try it before loading up with separate battery packs. Typically the PIC will reset if you get a glitch on the power. You...

I was able to find:

HPI Racing Sprint 2 Flux RTR w/Ford Mustang GT-R

Must be the same or similar. I looked at the specs and replacement parts and was able to find a picture of the ESC. ...

Hi Ken

Sorry to have not been very responsive. I had a mother board fail on my server and have been spending my time rebuilding the hardware and software...fun fun fun.

Yes I can read the...

Ken

You should download the data sheet for your PIC from MicroChip website.

Typically the max current any one pin can drive is 25mA, 100mA total for a port.

So whatever relay you choose must...

I'm not sure what the demo board really is that comes with the PICKIT2. If it has to be soldered, you may want to consider getting a proto or bread board to do your prototyping. This is a...

My mistake Dave///not sure how PICaxe came up come to think of it.


Git er done!

Hmmmm

Don't think I recommended PICAxe...Dave wrote something on it. I just noted that you need special PICs.

Maybe you didn't read my last post.

I'm reluctant to recommend a specific...

No perfect solution....

PICAxe are MicrChip CPUs that have a bootloader installed so you don't need a programmer to program them. You can't buy any old PIC and make it work, but apparently there...

Steering to find the source might not converge, but that is part of the fun so try it see what happens.

Dave recommended the PICKIT2 from MicroChip and buy PicBasic compiler. If you know C, you...

One thing you will need to do at the start is "global" scan to find the light to start with. It may or may not be in the limited forward acceptance of a detector array. So maybe a 360 azimuth...

Ah OK got it.

The problem with a simple light detector and lens is that it gives you no positional information as to where to go to seek higher intensity. The linescan sensor you mentioned does...

Take a look at the QTI Sensor on the Parallax site...only 6 bucks, emits and receives IR to follow line.

But I'm not sure if you want to follow a line or seek out a bright light??????

Hi Dave

I agree it depends on the level of glitches you are willing to put up with. I have done what Ken describes with a PIC in a single loop. The call to read PWMs is one element. Sensor...

Personally I would go with what I described....software control. But someone might come up with an elegant solution. I really don't think you have to keep up with the 25ms servo rate. I have done...

Mike is correct on the sampling times, however I have made things work well for this application at a much lower rate....basically whenever it gets to it. This can lead to some choppy response on...

The Basic Stamp has a function called PULSIN that will give you the width of a pulse on one of the input pins. You can sample multiple pins (input pulses). You can put these 3 PULSIN functions in a...

Hi Ken

My pleasure and good luck. Retired physicist here, always played with RC and processors/sensors....just not together. Now that I have time I, get to play with my toys:)

Happy to share...

Good plan Ken...and glad you are getting students involved.

I cannot comment on the language you quote since I have no experience with them. What you describe, however, sounds very well suited to...

Hi Ken

Just looked at the video. Remarkably, this is very similar to what I did and described in my earlier post. Some similarities/differences...I used a larger RC truck platform with 4WD (a...

Ken

You probably need to decide if you want the flexibility of a bare PIC or a package that is already programmed. I went with the PIC since I can basically make it do anything I want.

There...

Hi Ken

I'm out in Colorado, so don't know much about clubs in Mass, but you do have MIT there and they are well known for their work in robotics. You might see if you could connect with them. The...
