Configured processing interval in "ADC_Dual_Mode " example is not realistic

[StefanL38]

The "ADC_Dual_Mode" example is configured to process the buffer every millisecond:

Arduino_AdvancedAnalog/examples/Advanced/ADC_Dual_Mode/ADC_Dual_Mode.ino

Line 26 in 38836d5

if (millis() - last_millis > 1) {

This interval is nonsense because the example must acquire new values and print a significant number of characters in that time:

Arduino_AdvancedAnalog/examples/Advanced/ADC_Dual_Mode/ADC_Dual_Mode.ino

Lines 27 to 33 in 38836d5

	Serial.println(buf1.timestamp()); // Print buffer timestamp
	Serial.println(buf1[0]); // Print sample from first channel
	Serial.println(buf1[1]); // Print sample from second channel
	Serial.println(buf2.timestamp()); // Print buffer timestamp
	Serial.println(buf2[0]); // Print sample from first channel
	Serial.println(buf2[1]); // Print sample from second channel

This will take longer than a millisecond. And so the effective update rate will be slower than implied by the code.

Hey! Thanks for reporting!
Please, open a PR proposing a suitable delay time
Thanks

configured to process the buffer every millisecond:

No, it's not. It prints the values if at least 1 millisecond has passed since the last print, to throttle the output. This example is just meant to demonstrate how to configure dual ADCs, you should not be printing ADC values anyway. That said, please feel free to improve the example if you like.
