Howdy all,
I recently took a class from Microchip learning to use their PIC24F 16-
bit micros. I got the Explorer 16 development board and the ICD2 LE
and got everything up and running with their MPLAB IDE v8.02 yadda,
yadda. Everything is going very well, but I dont have any prior
experience using more lowly 8-bit micros.
A friend of mine wants me to design and build a little controller unit
to put inside of his remote control boat that will receive some of the
servo signals from a couple of different receiver channels and be able
to fire some rockets and trigger various aquatic peripherals. This
seems to me like I should look to an 8 or 14 pin 8-bit solution and
that a 100-pin 16-bit processor would be significant overkill
(understatement).
I looked at the receiver servo signals on a scope and they are strange
PWM type signals that vary in pulse width depending on what the
transmitter/controller is doing (not sure if I should average them to
DC and look at the DC level using an ADC or not). Anyway, it is my
job to receive the various servo signals from the receiver and write a
little program to have the micro control a couple of outputs to:
a) light a fuse on a bottlerocket
b) send out pulses to trigger a paintball firing mechanism (fully-
automatic or semi-automatic or one-shot).
c) perhaps a few other tricks.
My question is this....
1) Will my new ICD2 LE work with lowly 8-pin and 14-pin PIC 8-bit
micros in addition to the PIC24F 16-bit micros?
2) Although I have designed and build hundreds of my own PCBs in the
past, this project doesnt really warrant a custom designed and built
PCB...instead I would like to buy an "off the shelf" development board
that will allow an 8-pin or 14-pin micro to be used to accept a couple
of receiver servo pulse width inputs and actuate a couple of output
transistor/driver circuits for US$20-40ish.
Sure I could design my own PCB, but I would like to keep my actual
design time limited to a couple of hours tinkering with the code
instead of spinning a PCB, specing and ordering parts, etc.
Any suggestions on quick deployment general purpose PIC development
kits for such an application?
I found this...
http://www.talkingelectronics.com/projects/PIC_Lick-1/PicLick-1-P1.html
It looks like the best so far for $30 or so with the PCB and all
parts.
I also saw this, but would require more tinkering for the output
stages...
