JackyZhangFromSeeed 0:25c5f1b9f9e2 8 2015-4-17: initial version for v2
JackyZhangFromSeeed 0:25c5f1b9f9e2 9
JackyZhangFromSeeed 0:25c5f1b9f9e2 10 suli is designed for the purpose of reusing the high level implementation
JackyZhangFromSeeed 0:25c5f1b9f9e2 11 of each libraries for different platforms out of the hardware layer.
JackyZhangFromSeeed 0:25c5f1b9f9e2 12 suli2 is the new reversion of original suli. There're lot of improvements upon
JackyZhangFromSeeed 0:25c5f1b9f9e2 13 the previous version. Currently, it can be treated as the internal strategy for
JackyZhangFromSeeed 0:25c5f1b9f9e2 14 quick library development of seeed. But always welcome the community to
JackyZhangFromSeeed 0:25c5f1b9f9e2 15 follow the basis of suli to contribute grove libraries.
