Software Serial doesn't recognize 16.5Mhz

[Trakkasure]

I just received my radio blocks... while trying to run the test sketches, the DigiSpark arduino didn't wanna compile the SoftwareSerial code.


Arduino.app/Contents/Resources/Java/libraries/SoftwareSerial/SoftwareSerial.cpp line 57:
Update to:
#if F_CPU == 16000000 || F_CPU == 16500000


Allows it to compile. Not sure if it works yet.
I need to setup both nodes first to test the radio transmission.
I'll update later.

I've been working on timing setting for 16.5Mhz but had to jump back on concentrating on shipping this week.


Here is where I left off on them:

Code: [Select]


#elif F_CPU == 16500000


static const DELAY_TABLE PROGMEM table[] =
{
  //  baud    rxcenter   rxintra    rxstop    tx
  { 115200,   1,         18,        18,       12,    },
  { 57600,    10,        38,        38,       34,    },
  { 38400,    26,        59,        59,       56,    },
  { 31250,    32,        72,        72,       70,    },
  { 28800,    35,        79,        79,       76,    },
  { 19200,    56,        121,       121,      118,   },
  { 14400,    76,        161,       161,      158,   },
  { 9600,     118,       243,       243,      240,   },
  { 4800,     240,       489,       489,      486,   },
  { 2400,     486,       980,       980,      977,   },
  { 1200,     977,       1961,      1961,     1958,  },
  { 600,      1961,      3923,      3923,     3919,  },
  { 300,      3923,      7855,      7855,     7852,  },
};


const int XMIT_START_ADJUSTMENT = 5;




When the Radioblock kickstarter claimed to be digispark ready I let the creator know that it might take some work to support - perhaps ask him about it as well - so I can't say if it will work out of the box, but the timings above should be a good start.

Thanks for the code.


I've posted in their forum too.

Using 16Mhz timings at 16.5Mhz is only 3.125% off, it should work reliably enough for you to do some testings until you have this figured out.
