Joseph Ellsworth / Mbed 2 deprecated xj-Init-clock-to-compile-time-if-not-already-initialized-ds1302

Initialize clock chip to compile time the first time the program runs after that it will read the time from the clock chip. I find this easy since a quick recompile and load of utility sets the clock chip then we reload with the normal firmware. OK for use in low volume testing.

Initialize Clock To Compile Time

Initialize clock chip to compile time the first time the program runs after that it will read the time from the clock chip.

I find this an easy way to initialize my clock chip and then it stays set for as long as the battery lasts. I use a quick recompile then copy this utility to the mbed board where it sets the time and date. After than reload the mbed board with normal firmware and the clock remains set.

I use it for low volume testing.

Underlying library for parsing DATE and TIME is as follows:

The time supplied by compiler is UMT so you need to adjust for local time if needed.
