Review of the previous issue“Pi Zi Heng embedded semimonthly: issue 15”


Today is the autumn equinox. The autumn equinox is a beautiful and pleasant season.

The biggest hot spot in the near future is the release of Huawei Hongmeng 2.0 and the open source code. It has been one year since the concept version of Hongmeng 1.0 has been released. This time, we can finally see its true features. To tell you the truth, no matter how grand the concept function is, let’s directly look at the code completion.

Under the current situation, if Huawei Hongmeng succeeds, it is undoubtedly unprecedented to carry on the past and open up the future. Before that, Samsung and Microsoft had thought about challenging the mobile hegemony of Android and IOS systems, and both ended in failure. In short, wish Huawei, Hongmeng, come on!

This issue contains 1 piece of information, 2 items and 2 tools. I hope it will help you!


1. Horizon releases a new generation of edge AI chip sunrise 3

Recently, horizon held a new product release conference in Shenzhen with the theme of “release core efficiency”, and officially launched a new generation of aiot edge AI chip platform horizon sunrise 3.

Information homepage:https://www.horizon.ai/news-detail.html?id=19

Sunrise 3 integrates horizon’s most advanced Bernoulli 2.0 architecture AI engine (BPU), which can provide equivalent computing power of 5tops. The new BPU architecture greatly improves the support effect of the advanced CNN network architecture, and greatly reduces the utilization of DDR bandwidth by AI computing. Supported by horizon “Tiangong Kaiwu” Ai development platform, the algorithm development and deployment process is greatly simplified, and the landing cost of AI products is reduced.

1. Wukong robot – simple, flexible and elegant Chinese voice dialogue robot

Wukong robot project is an open source Chinese voice dialogue robot project developed and maintained by GitHub netizen wzpan, which can let interested developers quickly create personalized intelligent speakers.

Project home page:https://github.com/wzpan/wukong-robot

The characteristics of the project include:

-Modularization. Functional plug-ins, speech recognition, speech synthesis, dialogue robots are highly modular, and third-party plug-ins are maintained separately, which is convenient to inherit and develop their own plug-ins

2. Mini DSO – a low cost simple oscilloscope

This is a simple oscilloscope made of stc8a8k MCU. The microcontroller uses stc8a8k64s4a12 and works at 27MHz. The display screen adopts 0.96 OLED with a resolution of 128X64. The oscilloscope project is easy to use and covers the necessary measurement functions. Support normal mode, single mode, automatic mode, trigger mode selection, such as level trigger, with save settings.

The mini DSO input is single channel mode, and the second / grid size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100US, the voltage acquisition range is 0 to 30V, and the sampling rate can be achieved [email protected]/div.
