-In order to build MMDVM, you need to tell the Arduino GUI to link with the
-CMSIS DSP library, which is doesn't do by default.
-
-My development is on Windows and so I can vouch for the following instructions.
-
-For Arduino 1.6.3 with SAM 1.6.4
---------------------------------
-
-1. Go to the where the platform.txt file is located. On my Windows machine it's
-in:
-
-C:\Users\Jonathan\AppData\Roaming\Arduino15\packages\arduino\hardware\sam\1.6.4
-
-On Mac OS X it's located in:
-
-/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/sam
-Or
-~/Library/Arduino15/packages/arduino/hardware/sam/1.6.6
-
-2. You'll need to open the file in a text editor and find the line:
-
-## Combine gc-sections, archives, and objects
-recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} -mcpu={build.mcu} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" "-L{build.path}" -mthumb -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--warn-unresolved-symbols -Wl,--start-group "{build.path}/syscalls_sam3.c.o" {object_files} "{build.variant.path}/{build.variant_system_lib}" "{build.path}/{archive_file}" -Wl,--end-group -lm -gcc
-
-In my version it's line 73.
-
-3. Modify it to read as follows:
-
-## Combine gc-sections, archives, and objects
-recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} -mcpu={build.mcu} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" "-L{build.path}" -mthumb -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--warn-unresolved-symbols -Wl,--start-group "{build.path}/syscalls_sam3.c.o" {object_files} "{build.variant.path}/{build.variant_system_lib}" "{build.system.path}/CMSIS/CMSIS/Lib/ARM/arm_cortexM3l_math.lib" "{build.path}/{archive_file}" -Wl,--end-group -lm -gcc
-
-The change is near the end, and is the addition of:
-
-"{build.system.path}/CMSIS/CMSIS/Lib/ARM/arm_cortexM3l_math.lib"
-
-Which is the CMSIS AMR3 DSP library for little-endian operation.
-
-4. Save the file and start up the Arduino GUI and build MMDVM.
-
-I would like to get instructions for doing the same on a Linux platform. As a
-starter find the relevent platform.txt and try adding:
-
-"{build.system.path}/CMSIS/CMSIS/Lib/ARM/libarm_cortexM3l_math.a"
-
-or maybe:
-
-"{build.variant.path}/libarm_cortexM3l_math.a"
-
-Likely on Linux
-
-"{build.system.path}/CMSIS/CMSIS/Lib/GCC/libarm_cortexM3l_math.a"
-
-As with Arduino 1.6.7 with SAM 1.6.6, see below.
-
-
-For Arduino 1.6.7 with SAM 1.6.6 
---------------------------------
-(checked OK on Arduino 1.6.11 and SAM 1.6.9)
-
-1. Go to the where the platform.txt file is located. On my Windows machine it's
-in:
-
-C:\Users\Jonathan\AppData\Local\Arduino15\packages\arduino\hardware\sam\1.6.6
-
-On Mac OS X it's located in:
-
-/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/sam
-
-On Linux, it's located in my home directory, downloaded and extracted from Arduino website, but must be installed.
-
-/home/m1geo/arduino-1.6.7/hardware/arduino/sam 
-
-or
-
-/home/m1geo/.arduino15/packages/arduino/hardware/sam/1.6.9 (if you let the board/library manager install SAM)
-
-
-I (M1GEO) found it was necessary to download SAM-1.6.6 outside of the Arduino IDE, and manually extract the files. 
-  The Board Manager didn't seem to install the SAM files correctly. Here's how I did it:
-  
-  a) wget http://downloads.arduino.cc/cores/sam-1.6.6.tar.bz2 -O /tmp/sam-1.6.6.tar.bz2 (download and save in /tmp)
-  b) cd arduino-1.6.7/hardware/arduino/ (Arduino root, here, in my home directory)
-  c) tar xvfj /tmp/sam-1.6.6.tar.bz2
-
-2. You'll need to open the file (platform.txt) in a text editor and find the line:
-
-## Combine gc-sections, archives, and objects
-recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" -mcpu={build.mcu} -mthumb {compiler.c.elf.flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" "-L{build.path}" -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--start-group "{build.path}/core/syscalls_sam3.c.o" {object_files} "{build.variant.path}/{build.variant_system_lib}" "{build.path}/{archive_file}" -Wl,--end-group -lm -gcc
-
-In my version it's line 73.
-
-3. Modify it to read as follows:
-
-## Combine gc-sections, archives, and objects
-recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" -mcpu={build.mcu} -mthumb {compiler.c.elf.flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" "-L{build.path}" -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--start-group "{build.path}/core/syscalls_sam3.c.o" {object_files} "{build.variant.path}/{build.variant_system_lib}" "{build.system.path}/CMSIS/CMSIS/Lib/ARM/arm_cortexM3l_math.lib" "{build.path}/{archive_file}" -Wl,--end-group -lm -gcc
-
-The change is near the end, and is the addition of:
-
-"{build.system.path}/CMSIS/CMSIS/Lib/ARM/arm_cortexM3l_math.lib"
-
-On Linux, the path was found to differ slightly (GCC instead of ARM):
-
-"{build.system.path}/CMSIS/CMSIS/Lib/GCC/libarm_cortexM3l_math.a"
-
-Which is the CMSIS AMR3 DSP library for little-endian operation.
-
-4. Save the file and start up the Arduino GUI and build MMDVM.
-
-For Arduino 1.6.9 with SAM 1.6.8
---------------------------------
-
-1. Locate platform.txt. On Ubuntu 14.04 LTS x86_64 OS it is in:
-
-/home/$user/.arduino15/packages/arduino/hardware/sam/1.6.8/
-
-2. Open the file in a text editor and change the line:
-
-## Combine gc-sections, archives, and objects
-recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" -mcpu={build.mcu} -mthumb {compiler.c.elf.flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" "-L{build.path}" -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--start-group {compiler.combine.flags} {object_files} "{build.variant.path}/{build.variant_system_lib}" "{build.path}/{archive_file}" -Wl,--end-group -lm -gcc

-
-3. Save the file, open the Arduino IDE and build MMDVM

+This is the source code of the MMDVM firmware that supports D-Star, DMR, System Fusion, P25, NXDN, M17, POCSAG, AX.25, and FM modes.
 
 It runs on the Arduino Due, the ST-Micro STM32F4xxx and STM32F7xxx processors, as well as the Teensy 3.5/3.6. What these platforms have in common is the use of an ARM Cortex-M3, M4, or M7 processors with a minimum clock speed greater of 80 MHz, and access to at least one analogue to digital converter, one digital to analogue converter, as well as a number of GPIO pins.

+//X ABC Algorithm Random Number Generator for 8-Bit Devices:
+//This is a small PRNG, experimentally verified to have at least a 50 million byte period
+//by generating 50 million bytes and observing that there were no overapping sequences and repeats.
+//This generator passes serial correlation, entropy , Monte Carlo Pi value, arithmetic mean,
+//And many other statistical tests. This generator may have a period of up to 2^32, but this has
+//not been verified.
+//
+// By XORing 3 bytes into the a,b, and c registers, you can add in entropy from 
+//an external source easily.
+//
+//This generator is free to use, but is not suitable for cryptography due to its short period(by //cryptographic standards) and simple construction. No attempt was made to make this generator 
+// suitable for cryptographic use.
+//
+//Due to the use of a constant counter, the generator should be resistant to latching up.
+//A significant performance gain is had in that the x variable is only ever incremented.
+//
+//Only 4 bytes of ram are needed for the internal state, and generating a byte requires 3 XORs , //2 ADDs, one bit shift right , and one increment. Difficult or slow operations like multiply, etc 
+//were avoided for maximum speed on ultra low power devices.

+  @brief         Processing function for the Q31 Biquad cascade filter.
+  @param[in]     S         points to an instance of the Q31 Biquad cascade structure
+  @param[in]     pSrc      points to the block of input data
+  @param[out]    pDst      points to the block of output data
+  @param[in]     blockSize  number of samples to process
+
+  @par           Scaling and Overflow Behavior
+                   The function is implemented using an internal 64-bit accumulator.
+                   The accumulator has a 2.62 format and maintains full precision of the intermediate multiplication results but provides only a single guard bit.
+                   Thus, if the accumulator result overflows it wraps around rather than clip.
+                   In order to avoid overflows completely the input signal must be scaled down by 2 bits and lie in the range [-0.25 +0.25).
+                   After all 5 multiply-accumulates are performed, the 2.62 accumulator is shifted by <code>postShift</code> bits and the result truncated to
+                   1.31 format by discarding the low 32 bits.
+  @remark
+                   Refer to \ref arm_biquad_cascade_df1_fast_q31() for a faster but less precise implementation of this filter.

+  @brief         Processing function for the Q15 FIR filter (fast version).
+  @param[in]     S          points to an instance of the Q15 FIR filter structure
+  @param[in]     pSrc       points to the block of input data
+  @param[out]    pDst       points to the block of output data
+  @param[in]     blockSize  number of samples to process
+  @return        none
+
+  @par           Scaling and Overflow Behavior
+                   This fast version uses a 32-bit accumulator with 2.30 format.
+                   The accumulator maintains full precision of the intermediate multiplication results but provides only a single guard bit.
+                   Thus, if the accumulator result overflows it wraps around and distorts the result.
+                   In order to avoid overflows completely the input signal must be scaled down by log2(numTaps) bits.
+                   The 2.30 accumulator is then truncated to 2.15 format and saturated to yield the 1.15 result.
+
+  @remark
+                   Refer to \ref arm_fir_q15() for a slower implementation of this function which uses 64-bit accumulation to avoid wrap around distortion.  Both the slow and the fast versions use the same instance structure.
+                   Use function \ref arm_fir_init_q15() to initialize the filter structure.

+  @brief         Processing function for the Q15 FIR interpolator.
+  @param[in]     S          points to an instance of the Q15 FIR interpolator structure
+  @param[in]     pSrc       points to the block of input data

+  @param[in]     blockSize  number of samples to process
+  @return        none
+
+  @par           Scaling and Overflow Behavior
+                   The function is implemented using a 64-bit internal accumulator.
+                   Both coefficients and state variables are represented in 1.15 format and multiplications yield a 2.30 result.
+                   The 2.30 intermediate results are accumulated in a 64-bit accumulator in 34.30 format.
+                   There is no risk of internal overflow with this approach and the full precision of intermediate multiplications is preserved.
+                   After all additions have been performed, the accumulator is truncated to 34.15 format by discarding low 15 bits.
+                   Lastly, the accumulator is saturated to yield a result in 1.15 format.
