Hanshow CC2640 BLE E-Paper

汉朔电子价签的固件和蓝牙操作的web界面。

固件适配TI CC2640主控,实测能用的汉朔电子价签型号为Stellar-M3N@ E31A和Stellar-L3N@ E31A。

固件是基于https://github.com/muyuchl/cc2640BleEpd这个仓库的源码改的。添加了4阶灰度的实现和对接了下web界面,原作者的android app有点难用。

web界面是基于https://github.com/reece15/stellar-L3N-etag这个仓库的web_tools改的,删了点固件里没实现的功能,加了些灰度图相关的功能。因为传图的时候有时候蓝牙会自己断掉,不知道什么原因,所以在web端还加上了断线重发的功能。
