Abstract

I introduced R/C Servo I/F Board at Expansion Board for StarBoard Orange : R/C Servo I/F Board.

In this document I introduce a virtual product named "Kuma-chan servo kit".

Content

"Kuma-chan servo kit" are consist from
  • R/C Servo I/F Board with 16x2 character based LCD.
  • R/C Servo Motor with gears. (GWS SERVO - S03T 2BBMG)
  • AC-DC adapter (Output capacity : 5V 2.3A)

Box

Components

R/C Servo I/F Board

R/C Servo

Gears for R/C Servo

AC-DC Adapter

Setup

Configuration of StarBoard Orange

Remove LCD.
Check the LCD I/F configuration.

Connect R/C servo motors

Docking on your StarBoard Orange

Connect AC-DC adapter to DC input on R/C Servo I/F Board.
It's done.
Program
You can get a program from a link.
Try it
Download and unzip the program, and press reset button to reset your mbed.
The Network address is IP address for HTTP server on your mbed.
So you can connect from your PC, Mac, Linux, also iPod touch...
You can try to control a servo.

Summary

"Kuma-chan servo kit" is not a real product. (It's a joke.)
But the concept and the test program is not virtual.
So you can use it. :)

Thank you! It's fun!

Unfortunately, I don't have good idea (like your nice demo video) what I can do with this RC-servo but I tried to turn a papier-mâché custard-pudding :)

It works fine with my iPhone too!

Hi Tedd-san!

Oh! Thank you for your great report.

Yeah, I know you love custard-pudding. :)

The board has 3 channel R/C servo interfaces for example ... 'N', 'X', 'P' text lotation...

Anyway...

I have an interest the function of RPC. It's great!

There is no way to use the function with 8bits MPU.

So I created the demo.

Thank you so much for your great support.

Best regards

Shin.

Thanks Shin, I already checked it but could not find the whole main program (.cpp). If not, how to go about this. Love the concept!

or otherwise to use http://mbed.org/users/shintamainjp/programs/ServoInterfaceBoardExample1/lgv01k  do i have to add "servo.h" library

then  add

PwmOut rc(p21);

or

I just have to call  for example:  http://mbedipaddress/rpc/PwmOut/write 0.08     over the internet  assume using one servo only

any help would be appreciated

thanks once again.

Hi! Your project is great and very rewarding but i have a question about the servos settings. Where in your program can i set the frequency for a different servo with a different frequency? Thank you!
