Inter-Integrated Circuit, abbreviated as I2C is a serial bus short distance protocol developed by Philips Semiconductor about two decades ago to enhance communication between the core on the board and various other ICs involved around the core. • UART is simple protocol, it uses start bit (before data word), stop bits (one or two, after data word), parity bit (even or odd) in its base format for data formatting. I'm trying to implement a simple line-based protocol (every message is terminated by \r or ). 1 UART The control module interfaces to the UART and USB modules. The URM07 is an ultra low-power sensor. RDM6300 125KHz cardreader mini-module is designed for reading code from 125KHz card compatible read-only tags and read/write card. As part of the verification planning process, a test plan should be drawn up to list all the design features to be tested and to help identify the type of functional coverage required to check that all the tests have been run for all conditions. You might also have a look at PPP to see if there are something useful parts. The article shows how to determine the tolerance for the UART clock source at both ends of an asynchronous link. 1 3G-SDI Level B Stream Selection 11 4 VP-790 Protocol - Communication 1. Here is the register mapping table:. You will see that the Tiva has more inputs/outputs for each UART.
