Delay like function for LowPower Arduino library

Delay like function for LowPower Arduino library

Here is delay-like function for Low-Power Arduino library. All delay measurments are performed with ATMega328pu (8MHz internal, 3.3V).

Real delays

  • powerDownDelay(60000) = 60002.256ms
  • powerDownDelay(30000) = 30001.9615ms
  • powerDownDelay(15000) = 15001.783ms
  • powerDownDelay(10000) = 10000.08ms
  • powerDownDelay(5000) = 5000.3095ms
  • powerDownDelay(2000) = 2007.191ms

Parse JSON Date created by .NET, for example: /Date(1378670400000-0500)/
protected static Date parseJsonDate(String date) {
Pattern DATE_PATTERN = Pattern.compile("/Date\\((-?\\d+)([-+]\\d{4})?\\)/");
Matcher m = DATE_PATTERN.matcher(date);
if (m.matches()) {
long time = Long.parseLong(m.group(1));
long zone = 0;
if (m.group(2) != null && m.group(2).length() > 0)
zone = Integer.parseInt(m.group(2)) / 100 * 1000 * 60 * 60;
