ShieldBuddy v1.32 add-in released!

The new v1.32 ShieldBuddy add-in is now available. This adds a number of new features:

(i) It is now possible to set any PWM frequency for analogWrite() using the useCustomPwmFreq(Freq) function:

/* Use 4000Hz carrier */
useCustomPwmFreq(4000);

The maximum frequency that may be set is 390kHz. The minimum is 5.6Hz.

(ii) The TriLib fixed point DSP library has now been integrated. This gives assembler-coded functions (callable from C/C++/Arduino) for:

• Complex Arithmetic
• Vector Arithmetic
• FIR Filters
• IIR Filters
• Adaptive Filters
• Fast Fourier Transforms
• Discrete Cosine Transform
• Mathematical functions
• Matrix operations
• Statistical functions

You can do a 32 point FFT on two series in parallel in about 3.8us with this on any CPU core.
