Using SoftwareSerial with custom baud rates

The code has a "DebugPulse()" call in the inner loop. It looks like the intent was to fine-tune the constants with an oscilloscope... but then when you take out the "#define _DEBUG 1" the timing would be different! My calculations show: 8 MHz: subtract 8.5 cycles and divide the remainder by 3.5 16 MHz: subtract 65 cycles and divide the remainder by 14.0 20 MHz: subtract 13 cycles and divide the remainder by 7.0 For example, 7800 baud: 8,000,000/7800 = 1025.64 - 8.5 = 1019.14 / 3.5 = 291 (9…
