Problem Solved:



Still relevant to this thread:

With the latest versions of Arduino you need to change a line in the code given in

The reason is given in http://forum.arduino.cc/index.php?topic=272313.0

PROGMEM  prog_uchar sine256[]  = {
PROGMEM  byte sine256[]  = {       ...or
PROGMEM  char sine256[]  = {

Both work for me but I don't which is the more correct; byte seems the more logical.



why not call  setupSPI();  in  setup()  ??

The same code....

and try Serial.begin(115200)  then you have more time for other things....

I would like to set up a loop whereby six different frequencies will run , one after the other. Is this the proper board

for this undertaking? I am familiar with arduino but writing code makes my head hurt. I want to use it in conjunction with some experiments that may be very useful in combating nuclear radiation, so far my tests have been somewhat successful, but I think using the varied frequencies would be much better and cannot see myself getting up every 4 hours to change the frequency...Can you help?

Can you help?
Maybe, but details like the 6 specific frequencies would make your question clearer...
