i2c总线是由PHILIPS公司开发的一种简单、「双向二线制同步串行总线」。关于i2c的使用,并不陌生,C51、ARM、MSP430等,都基本集成硬件i2c,或者不集成i2c的,可以根据总线时序图使用普通IO口翻转模拟一根i2c总线。 对于流行的stm32饱受诟病的硬件i2c,相信很多人 ...
I2C不是AUTOSAR中标准的MCAL模块,所以I2C在车载电控件中基本不用(一般都使用SPI),但是因为I2C一主多从只需要两个Pin脚就能控制多个外设的特性,在一些带SOC的控制器中会使用到,且Vector的SIP包中也有I2C模块,所有有必要学下以下,本文就概要的介绍下TC3xx芯片 ...
i2c的设备树和驱动是如何匹配以及何时调用probe的?粉丝手里的I2C外设是ov5640,一个摄像头。粉丝提问,一口君必须安排。 i2c_device_match(),匹配总线维护的驱动链表和设备信息链表,如果其中名字完全相同,则返回true,否则false;i2c_device_probe(),当 ...
Bytom -- April 2, 2013-- Digital Core Design, an IP Core and System on Chip design house from Poland, has introduced its newest I2C Bus Interface soft core. It is fully compatible with Philips v. 3.0 ...
When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, ...
The I2C Bus – From Humble Beginnings to New Uses The simplicity and low cost of the I2C bus has enticed electronic engineers to find more uses for the two-wire Inter-Integrated-Circuit protocol, and ...
NXP Semiconductors’ family of level shifting bus buffers are detailed in this application note that discusses device operation, maximum cable length and frequency ...
A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...
NXP Semiconductors has introduced its first no-offset I2C-bus buffers, which are designed to isolate capacitance and so allow interface with other bus buffers. Significantly, the bus buffers use the ...
