Math Object List:

Maidenhead, a shorthand for latitude and longitude, is used by Amateur Radio operators (hams) for use in identifying a location. For some contests, VHF, UHF+, Maidenhead is used as a ...

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 ...

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

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

Object for converting the output of the Sensirion SHT11 to a more usable form.

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 ...

A modified version of Float32Full that allocates cogs dynamically. Somewhat slower than the original, but only uses up one cog, and can be shared between multiple objects. Just call it ...

Update to the dynamic math lib. It's faster and occupies about half the space as it used to.

This object uses an ADC to take readings from a 5DOF Accelerometer/Gyro unit and send them through a Kalman filter. This filter maintains an accurate angle, gyro rate and gyro ...

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

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 ...
