 | | RCX Firmware and SP

Hi All, After a very frustrating weekend of fiddling with pbFORTH, I caved and asked Kekoa to help with a problem I was having with read_sensor() and pbFORTH. The problem we (mostly he) unearthed has to do with the SP and RCX firmware routines, so I (...) (25 years ago, 17-Oct-99, to lugnet.robotics, lugnet.robotics.rcx.legos, lugnet.robotics.rcx.pbforth)

| | Re:Solved?? rotation sensor problem
|
|
On Sep.10,I posted the message regarding rotation-sensor problem. I realized that the first threshold value '0x6fc0' in CURRENT_STATE is too small. Some sensors give raw values around 0x7000. #define CURRENT_STATE (raw<0x6fc0?STATE_0:...STATE_3))) (...) (25 years ago, 17-Oct-99, to lugnet.robotics.rcx.legos)

It's interesting you mention this. I have also started to use RJ11 and RJ45 connectors in my constructions. It is a neat and compact way of routing 2, 4, 6, or 8 wires around.
