Hi Scott,
there is lots of technical info available. The H8/3297 series hardware
manual is probably what you're looking for:
http://www.halsp.hitachi.com/tech_prod/h_micon/3_h8300/3_h8_300/h33th014d2/html/h3314frm.htm
A pdf version is available on the same site.
More specifically, the microcontroller has 8 A/D input pins. Right now,
four of them are used - Sensor 1 through 3 and battery voltage. These
are A/D channels 0-3 in group 0, so they take pins AD0..AD3. However,
the A/D input pins double as Port 7 digital input pins. Pin 6,7 are
connected to the program and view buttons, respectively. This leaves
candidates AD4/5.

| Hi All, Does anyone have any information regarding how the I/O ports interface to the micro-controller. I would like to do some work on expanding the number and types of sensors. But, I'm finding it difficult to locate technical information on the (...) (26 years ago, 11-Dec-98, to lugnet.robotics)
