share in China is now only 2.2%.Previously, Samsung is the world's second largest mobile phone market in India's first brand, currently, Xiaomi has surpassed Samsung in the Indian market, become the market occupies the first mobile phone brand.Why does Samsung want to sell chips? Mobile but Huawei Xiaomi, semiconductor good money!In addition, Samsung's advantage in the semiconductor market is not stable. Andrew Norwood, vice president of Gartner Research, says Samsung is currently occupying the

Compared to MTK function phones, these predecessors are mostly more complex than the BP portion of a gsm/gprs,3g phone that supports only 2 bands. If the MTK's B

The earliest brew platform was launched in September 2001 and is mainly used by CDMA mobile operators in the United States.
The brew platform consists of an application runtime environment and one end-to-end software publishing system. Allow developers and mobile operators to publish apps to brew phones and monetize them. Brew is a binary Runtime environment for wireless abbreviation.
The platform is developed and fully owned by Qualcomm.

After two development of arm, it became SOC (System on chip) chip system, for example, STM developed two CONTEX-M3 version of ARM processor, and STM32, Freescale Corporation ( March 2015 was acquired by NXP in September 2016 by Qualcomm, and the CONTEX-M4 version of the ARM processor was developed two times by the company's K60.

IAR usage notes (1)
At a.m. on October 10, August 8, the topic of the online discussion on China power grid was "the development and debugging of NXP Semiconductors Based on the lpc2000 microcontroller ". I tried to use IAR in the lab at night, but I was still unfamiliar with it. So I downloaded the PPT for this online discussion to my machine and checked it again. However, I am tired of reading the PPT. I 'd better remember the key points.

First, let's take a look at the configuration of vivo X6S Plus. It uses a Qualcomm Yunlong 652 eight-core processor, with 4 gb ram and 64 gb rom. The screen uses a 5.7 inch 1080 P Super AMOLED screen, the camera uses a 16 million pixel rear camera and a 8 million front camera, and the battery power is 3000 mAh. We will also introduce the specific performance in the following individual evaluations. Vivo X6S Plus
Currently, arm is common in the Chinese market, including NXP (Philips), Samsung, Atmel, Ti, and Adi. According to user requirements and application fields, you can select from the following aspects:
1. Speed (for common applications): The main clock speed of ARM7 is 20 ~ 133 m, 100 ~ 233 m, arm10 up to 700 m, if the speed requirement is higher, you can also use multi-core arm, such as minspeed ARM chips.
2. Memory (conventional applications): Gener

Here, the value 0 after spidev @ 0 indicates the SPI slave device selected by the SPI pin, which corresponds to the struct spi_master struct member num_chipselect. So why do we use cs0. First, let's look at the pins corresponding to the SPI controller we use.
