 | | RCX port information
|
| 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)

| Hi Scott, there is lots of technical info available. The H8/3297 series hardware manual is probably what you're looking for: (URL) pdf version is available on the same site. More specifically, the microcontroller has 8 A/D input pins. Right now, (...) (26 years ago, 12-Dec-98, to lugnet.robotics)

| (...) Whoa... so you mean, I can just like, take apart a 9V lead, solder them to those pins, and have 2 extra sensor inputs? or is there extra 'lectronics involved? Jasper (26 years ago, 17-Dec-98, to lugnet.robotics)

| (...) Nobody tried so far. The above is merely speculation - that's why I said "candidates". Should the pins turn out to be unused, legOS will support 6 A/D channels with minor changes. I have some software to work on right now, and I have a student (...) (26 years ago, 17-Dec-98, to lugnet.robotics)

They might, however, be tied to Vss or Vdd, so make sure you don't short anything out if do attempt to solder something to the extra (...) (25 years ago, 21-Dec-98, to lugnet.robotics)
