A SoftwareSerial library allows serial communication on any of the Uno's digital pins. The ATmega328 also supports I2C (TWI) and SPI communication. The Arduino Software (IDE) includes a Wire library to simplify use of the I2C bus; see the documentation for details. For SPI communication, use...
在点对点的通信中,SPI接口不需要进行寻址操作,且为全双工通信,显得简单高效。在多个从设备的系统中,每个从设备需要独立的使能信号,硬件上比I2C系统要稍微复杂一些。 例:现有1,2号设备支持SPI接口,则可以都挂到主控的SPI线上,之后如果要控制1号设备,则由主控发送CS=1号,选中1号设备,那么1号设备就可以通过MOSI,MI...
可是苦于没有编程器,寻遍网络后找到几种解决方案: arduino刷,树莓派I2C口刷,linux下用vga口刷,并口线刷,拆EEPROM刷 正好arduino在手边,于是就先测试这个方法吧, 大致流程就是利用arduino的I2C口和驱动板通信, 然后利用SPI口上传或下载驱动文件到驱动板 先把硬件搭起来吧, 手上没有SD卡模块,正好利用一个坏掉的...
Arduino Uno开发板基于ATmega328P AVR微控制器。 它有32KB的闪存、2KB的SRAM、1KB的EEPROM。 它具有丰富的片上外设(6个PWM通道、10位ADC、SPI、I2C、UART接口以及触摸库支持)。 任何集成开发环境的一个最重要的方面是能够编程特定的微控制器。 为了使用Atmel Studio编程Arduino Uno开发板,我们需要一个称为avrdude的...

Two Wire Interface (TWI/I2C) is for sending and receiving data over a net of devices or sensors. This library allows you to communicate with I2C/TWI devices. On the Arduino, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. So, you ask wh...
