READ ME for Software package provided with application note AN5092

The software package contains an IDE project for Greenhills Multi IDE, with Debugger start scripts for the Lauterbach T32 tool

The project does the following:

The Sigma delta ADC converts channel AN0 (Pin PB1). The results of the conversion are tranferred by DMA to the memory array SDADC1_RESULTS.
The results in SDADC on are then passed through three seperate LSP filters to contrast the performance of filters written in C, LSP assemble and LSP intrinsics.

The C FIR filter stores its results in the array C_FIR_OUT
The LSP assembly filter stores its results in the array LSP_FIR_OUT
The LSP intrinsics filter stores its results in the array LSP_FIR_OUT_INTRI

All three filters use the same co-efficients for a 9KHz low pass filter.

To test the operation supply AN0 with various input signals, and observe the filter outputs in the Lauterbach windows for each result array
