Hi, I just opened a pull request that implements tickless operation during idle: https://github.com/apache/incubator-mynewt-core/pull/34
The motivation is to reduce power consumption by putting the CPU to sleep when the OS does not have any useful work to do. At the moment the power saving only extends to the CPU but hopefully this provides a foundation to add off-cpu peripherals and i/o going forward. If you have any comments let me know and we can iterate on the patch. best Neel
