 | | Motor output
|
| Hi! When I work with the motor outputs, I found that the outputs are not linear. The "motor(m,p)" changes the output only in an increment 10 of p. Is there anyway I can get a more presiced output? Thanks. Keith (26 years ago, 28-Oct-98, to lugnet.robotics.handyboard)

| Hi all, Does anyone know how to convert floating point variables to integers in IC? I want to use the control the motor using an algorithm. However, that algorithm always return a floating point number, and motor(m,p) can only use integer p. Keith (26 years ago, 29-Sep-98, to lugnet.robotics.handyboard)

I'm seeing two main problems. 1) Some keys give 35 bits of data, and some give 38 bits. 2) (...) (26 years ago, 11-Feb-99, to lugnet.robotics.handyboard)

| Keith, The way to convert from floating point to int and vice versa in C is called typed casting. It is accomplished as follows: integer_number = (int)floating_point_number; for converting float to int. To convert the other way, simply type: (...)

| Keith, Try an LM567. It's a tone decoder with PLL and VCO. Basically set the internal freq. of the 567 any where between .01 Hz up to I think 500 kHz. Feed a signal into the 567 and if the freq's match up, the 567's output goes low. I've been (...) (28 years ago, 16-Jan-97, to lugnet.robotics.handyboard)
