Object List:

Add a touch switch to your project using only one resistor and a Propeller pin. Might need some tweaking for your project. Can sense your finger through the plastic wall ...

This object grew out of a discussion with deSilva. It is an extension of graphics.spin that allows for using the ROM font, Clemens font and the standard vector font. It ...

Object J-SonarSFR04 allows to read out 2-pin sonar SFR-04, no dependences.
Demo displays results in cm, requires TV_Text

This object handles the storage and retreval of variables (indexed by arbitrary word-sized integers) and data which need to persist across power cycles. Very easy to use, and thread safe. ...

In-place base64 decoder.

This terminal application shows the usage of the "FPU_Matrix_Driver.spin" object. The driver "expands" the matrix operation command set of uM-FPU v3.1 and provides the user a simple interface for calculations ...

This terminal application is a Standard Kalman filter. It uses the "FPU_Matrix_Driver.spin" object. The general coding framework is demonstrated with the "Bicycle with GPS" example. Kalman filters with matrices up ...

This terminal application is a Steady State Kalman filter. It uses the "FPU_Matrix_Driver.spin" object. The general coding framework is demonstrated with the "Bicycle with better GPS" example. Steady State Kalman ...

This terminal application is an Extended Kalman filter based upon the "FPU_Matrix_Driver.spin" object. The general coding framework is demonstrated with the "Tracking Ship" example. Extended Kalman filters with matrices up ...

This small object allows you to calculate MD5 hashes. Written entirely in Spin.
