Amperometric Hardfault

[sebastian-schneider-eng]

I have successfully integrated your examples into a STM32H7 and can perform the Amperometric measurement. I however realized, that if I am breaking the SW execution with the debugger, that a hardfault exception is occurring. The reason for that is that your Amperometric.c file is writing into memory areas which is not within the passed buffer. Possible work around:

1. Add a size check here:

   ad5940-examples/examples/AD5940_Amperometric/Amperometric.c

   Line 438 in 08c2331

   FifoCnt = AD5940_FIFOGetCnt();

2. Changing APPBUFF_SIZE to 1024 which is reflecting the internal fifo size:

   ad5940-examples/examples/AD5940_Amperometric/AD5940Main.c

   Line 21 in 08c2331

   #define APPBUFF_SIZE 1000
