1-wire device interface routines and demos. Low-level routines include network device search and CRC-8 calculation.

A 1-wire bus interface, compatible with Cam Thompson's excellent module, but written entirely in Spin. Does not require an extra cog. Requires an 80 MHz clock.

A 160 x 120 6 Bits Per Pixel VGA driver that runs on one cog. The code has been fully optimized with a super simple spin interface for maximum speed ...

My initial hack at interfacing a Power Tip PC2004LRF LCD display to the prop chip. Uses only 3 I/O lines; clock, data, E.
The three methods in the object ...

For Amateur Radio enthusiasts working with Microwaves and GPS stabilized oscillators I produced two chips for 3Dfix detection and display of other GPS parameters. The first thing I did when ...

Infinite Implulse Response (IIR) Recursive filter, implemented in pasm, with recursion. Starts a cog which continuously polls a memory location looking for a data value. The design objective for this ...

A 4-element infinite impulse response (IIR) digital filter with recursion, implemented in spin. This filter is best suited for low-to-moderate bandwidth filtering applications (e.g. filtering accelerometer or Ping))) data). Uses ...

This is a quick small modification to Chip's TV_TEXT.spin and TV.spin routines, that allow 40x30 tile text display in NTSC ( or PAL ) using the ROM FONT, which as ...
