Could someone tell me how to use the hog_processor(). I want to dedicate the controller to only one task. I tried the following program but it did not go faster than 700HZ. void main() { while(1) { hog_processor(); v_opt = analog(0); /*measure (...)

(...) Brian, The RAM memory space is divided into two big parts very roughly like this: 0x8000 - about 0xBE00 or so = your "user" program (the C program sent by I-C) 0xBFxx - 0xBFFF = interrupt vector table (immovable!) 0xC000 - 0xFEFF = PCODE.S19 (...)

(...) Do you happen to know if those changes are linear? Something like this would make a cool replacement for the MAS on the Talon. It uses a series of honeycombs (that form little diamond shapes). Then it measures the number of spinning vortices (...) (26 years ago, 17-Jun-98, to lugnet.robotics.handyboard)

The classic small air flow sensor is a hot-wire-anemometer. Just position a short piece of very fine wire in the airflow and normal to it, run a constant current thru it, and measure the voltage change due to the cooling effect of the airflow. Works (...)

Elektor had published a similar circuit for detecting air leaks. The heated transistor and another transistor acting as temp. sensor were glued together using heatsink compound. You had then to nullify/calibrate a meter at ambient temp. when the (...) (26 years ago, 16-Jun-98, to lugnet.robotics.handyboard)
