 | | Broken Charger/Interface board--last chapter
|
|
Well, it looks like reparing this charger/interface board is beyond me. I have now replaced all the capacitors, both 'lytic and not, and the MAX 232. I'have even been able to get an original Max232CPE. But the board doesn't work still. I get a (...) (24 years ago, 28-Jan-02, to lugnet.robotics.handyboard)

I received this worm from this list today, and it got past six different virusscanners. It's pretty new, in other words. I haven't yet found out what it does besides deleting itself and starting to send mails. Don't try and run the .com file (...) (24 years ago, 28-Jan-02, to lugnet.robotics)

Greetings, From the specs ((URL) the unit you have (LVS) supports a RS232C level connection. Since the HandyBoard uses TTL level signals, you would need an RS232C to TTL interface. This interface would be similar to the one used on the serial (...) (24 years ago, 27-Jan-02, to lugnet.robotics.handyboard)

Be sure you get the proper Max232 chip. I bought another, because I was having serial port problems, and thought it might be the Max232 chip... But the new one I bought wasnt *quite* right. What happened was in IC I could download pcode if I tried (...) (24 years ago, 27-Jan-02, to lugnet.robotics.handyboard)

(...) This is absolutely the right group! If you do searches on 'skipped counts' or similar wording you will find lots of posts on the rotation sensor missing counts at low speeds. And if you want to get to the bottom line quickly, check this (...) (24 years ago, 27-Jan-02, to lugnet.robotics)

| | "Servo" Driver for NQC
|
|
Hi All, I've got a bit of a problem! Whenever I do a cartesian (or other) robot model, I typically (in NQC) will program a "driver" which can spin the motors with the rotation sensors to any position and delecerate to finely reach the destination. (...) (24 years ago, 27-Jan-02, to lugnet.robotics)

|
|
I've been working with NQC for 2.5 years and I have never come across these errors. I have been unsuccessful in my attempts to solve the problems. Perhaps someone already knows the answer. Here are some screen shots from the computer. As you can (...) (24 years ago, 27-Jan-02, to lugnet.robotics.rcx.nqc)

All the circuit boards have been cleverly designed to allow interfacing between the sensors and the processor boards. The Lego CPU (aka the RCX) uses an active sensor (...)
