You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a ...
The 0M13320 is an I2C development kit that comes with a number of target devices for exploring the I2C-bus. For those who may be unfamiliar, the I2C is a communications bus, and requires only two ...
Several of the Mid-Range Enhanced Core PIC16 microcontroller devices have a Master Synchronous Serial Port (MSSP). The MSSP module can be used to implement either I2CTM or SPI communications protocol.
