The RIO-MP is a general purpose I / O board designed for use with Rigel
Corporationsí family of 8 and 16-bit embedded controllers. The development
and implementation of application-specific microcontroller based prototype
circuits is significantly simplified with the RIO-MP breadboard area, the
three terminal strips, and the input / output devices. These provide
flexibility for connecting prototyping components to the microcontroller
lines, and for developing and debugging user-designed analog and digital
A variety of I / O devices are available on
the RIO board including; 8 LEDs, 10 push buttons, 2 seven segment displays, 4
potentiometers, 8 toggle switches, a speaker with amplifier, 2x16 LCD display,
16 button keypad, and 2 stepper motor ICs. There is also an open collector for
high current / high voltage inputs and outputs to the board. These components
are referred to as the User Input Output Devices (UIOD).
There are 4 IDC headers on the RIO-MP board
correspond to the I / O headers found on Rigelís various embedded control
boards. The IDC headers are used to connect the controllers to the RIO board.
These IDC headers may be used to connect your own board to the RIO-MP. Only
one embedded controller should be plugged into the RIO board at a time.
