|
|
Last year in my 6.270-style course the students used "set_digital_threshold()" which was in lib_r22.c. With the newer IC I can't find it.

(...) Ed -- are you referring here to IC's mechanism for linking to assembly language files, the "IC Binary" interface? It's really not too hard to use, and allows users to create assembly language programs that are callable from IC using the C (...) (28 years ago, 27-Oct-96, to lugnet.robotics.handyboard)

Well, I haven't looked at the sonar routines, but my guess is that 17 feet round trip at around 1ms / foot each way is close to 32.768 ms, which is when the 16 bit timer in the 6811 overflows (the 6811 clocks the 16-bit counter at 2 Mhz). One idea (...) (28 years ago, 26-Oct-96, to lugnet.robotics.handyboard)
