最近做了一个外包项目,在mt6261上实现二维码的展示和扫码功能。

拒绝造轮子,所以当然要选择开源库。

由于是mtk功能机平台,只支持c,所以c++和java什么的就不考虑了。

二维码的编码,选择了qrencode,这个移植比较简单,不多说。

二维码的扫描算法,走了一些弯路。一开始根据网上的扫描算法速度对比,选择了quirc。但是移植好了实际上机测试,完全不是那回事,速度慢的要死,十几秒没反应,机器直接重启了。查了下原因,才发现,原来它使用了浮点算法,而mt6261根本就不支持硬件浮点计算,是用的软浮点,怪不得这么慢!

最后选择了zbar,并进行了裁剪和优化,运行效果良好,不到0.5秒就能完成从扫描到识别出二维码的操作。

源码就不贴出来了,外包项目,代码还是要适当保密。

    On another call http://cnpcl.com/stmap_81dcevos.html?prinivil.capecitabine.levitra.secnidazole levocetirizine dihydrochloride 5 mg montelukast 10 mg Attaullah Khogyani, a spokesman for the provincial governor, said the explosion occurred around 1 p.m. and that many of the wounded were Afghan government employees working in nearby offices. Soldiers guarding the compound managed to kill the militants on foot after the explosion, he said. He said four soldiers and five attackers died, in addition to the car bomber.

It boasts a claimed 24.1mpg, thanks in part to a newly adopted version of the cylinder-on-demand system, which deactivates six-cylinders when the engine is under low loads.

If a team thinks they can change that Jennings has the higher ceiling, but I’d lean Teague right now because I can see his improvement.

    I'd like to apply for this job https://venedikestate.com/pharmacy/stmap_81aaschp.html?cialis.tolterodine.spironolactone benadryl directions In purely sporting terms, one would hope that Australia can somehow spring into life and bowl them out before that lead reaches truly impossible proportions, but with the way the Aussies are batting, maybe it already has. We'll just grab a few more emails, and then I will hand you over to Rob Smyth for the afternoon session.
