 | | NQC and RCXCC
|
|
Using NQC together with RCXCC (by Mark Overmars) is a fine combination that fulfills my demands for writing software, debugging and testing. Unfortunately, Mark Overmars, the author of RCXCC will not do any further development for this product. (...) (24 years ago, 19-Oct-00, to lugnet.robotics.rcx.nqc)

| | Connecting 2 RCXs
|
|
The IR interface is one way to establish a "connection" via messages between 2 RCXs and it works fine if both of the RCXs will receive a message - directly or by multiple reflections within the room. However, it is a slow communication. My problem (...) (24 years ago, 19-Oct-00, to lugnet.robotics.rcx.nqc)

| | LNP Packet Handlers on RCX

I remember reading somewhere a while back, when I first started dabbling with LNP, that LNP handlers on the RCX side were called from interrupts and therefore doing things like memory allocation, msleep, heavy processing, etc. were not good ideas.

| | Re: Vision Command
|
|
No. There isn't any. You cannot control the camera form NQC or the RCX for that matter. You can respond to the messages that the Camera sends to the brick via Message(). I hope this syntax is right.... until(Message)>0); switch(Message()) case 1: // (...) (24 years ago, 18-Oct-00, to lugnet.robotics.rcx.nqc)

Hi, (Sorry, my English is not good) I would like to know if it's possible to use legOS (LNP) to get communications between RCXs without the PC, I mean, without an intermediate between the RCXs. And, if it's possible, how can I do that ? I'm using 3 (...) (24 years ago, 17-Oct-00, to lugnet.robotics.rcx.legos)

Not exactly.... The output is an analog voltage, meaning it's not exactly a digital TTL 0 volts or 5 volts, but ranges from 200mv (call this low) to Vcc-200mv (call this high). But this is a PWM output, meaning that with the chip stationary with (...) (24 years ago, 16-Oct-00, to lugnet.robotics.rcx, lugnet.robotics)

From looking at the data sheets, it's going to be a bit more of a project than just "hooking it up". At a minimum you'll need to have a small micro to decode the dual PWM outputs, and they (AD) have a data sheet describing the use of a Parallax (...)
