On Randomness

To avoid de-railing the choplifter thread, I’m opening this thread to discuss random number generators on the Arduboy. Idea: Remove the random and regain 300 bytes of Flash Here’s a simple test program: #include <Arduboy2.h> Arduboy2 arduboy; unsigned long jsr; void setup() { arduboy.boot(); arduboy.clear(); power_adc_enable(); ADCSRA |= _BV(ADSC); while (bit_is_set(ADCSRA, ADSC)) { } jsr = ((unsigned long)ADC << 16) + micros(); power_adc_disable(); // randomSeed( seed )…
