Math Object List:

If you remember learning the basics of graphing and rates of change from Algreba 1, that's what this program is. Just like using 2 sets of coordinates to graph a ...

This PST application shows the first Fixed-point arithmetic library object on OBEX. The "SPIN_TrigPack" object is a complete Fixed-point package with the basic trigonometric functions for robot and navigation projects. ...

This PST application includes three steps of the make and use of a simple and general mathematical sensor model for 3-axis MEMS sensors in embedded applications. This Calibration/Error Model works ...

v1.2: Updates 1.1 with StringToFloat
v1.1: This is an update to the FloatString object. It adds the FloatToFormat routine to return a string of up to 9 characters with the ...

This object provides the following integer math routines, written in Spin:

64 / 32 = 32 unsigned division;
(32 * 32 = 64) / 32 = 32 unsigned "fractional" ...

This Parallax Serial Terminal (PST) demo application introduces the 'GPS_Str_NMEA_Lite.spin v1.0' and the 'GPS_Float_Lite.spin v1.0' driver objects.
The 'GPS_Str_NMEA_Lite' driver interfaces the Propeller to a GPS receiver. This ...

A robust GPS NMEA parser in the 'GPS Str NMEA' object with float interface and navigation routines in the 'GPS Float' object

This is a simple SPIN CRC8 object. You can send either a string or a pointer to a byte array. I'll add CRC16 and CRC32 at some point but right ...

This object implements the RC4 cryptography algorithm. Has a single function that will encrypt or decrypt an expression based on a given password.

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 ...
