Signal Generation & Processing Object List:

This object is used to interface to the Victor 880 series speed controllers from IFI Robotics. These are high amperage controllers, reasonably priced, and interface easily to projects (To drive ...

Control up to 32 servos without external hardware.

History:
Version 1 - - initial concept
Version 2 - (03-08-2006) - Beta release

This object reads standard R/C servo pulse widths from a device such as a receiver. It can read an arbitrary number of channels and stores the pulse widths as integer ...

This object uses counters to monitor 6 pins for RC inputs. In the demo, pins 1 - 6 are connected to a Radio Control receiver or other device which outputs ...

PWM_32_v2 - Control up to 32 independent PWM signals.
Features include:
- Phase Sync between multiple PWM pins
- 0% to 100% Duty control
- ...

Provides up to 8 channels of fast PWM output per cog, generated by the Propeller's video circuitry.

This object emulates a Playstation 2 Dual Shock controller. Run five wires between the Propeller and a Playstation or Playstation 2 console, and the Propeller can impersonate a controller. Use ...

Very Small Driver for PCF8574 I2C 8-bit I/O Expander. Only 81 longs in size. Based off of from Michel Green's "Basic I2C Driver."

Moving average filter, implemented in PASM, with recursion. Starts a cog which continuously polls a memory location looking for a data value. Max filter bandwidth ~1M samples/sec @ 80 MHz, ...

Written in Asm this LED Sequencer in one cog is also usable as an I/O controller or simple logic pattern generator. Suitable for such projects as animated displays and simple ...
