Format and speed from question one:

Format: 1 start bit, 8 data bits, 1 odd parity bit, 1 stop bit.

Speed: baudrate of 9,600, transmitting character 'W'

data rate = baud rate * (data bits / frame bits)

Complete the function below for serial send (char my txt) to implement the UART protocol in software. Implement the format and speed specified in Question 1. Assume that Port B was already initialized and configured by the main program so that pin 3 is an output. Partial code for the function is provided. Finish the remaining code. Assume you have the following function: wait_us (float WaitTime) waits for WaitTime microseconds before continuing // Send my_txt out of Port B pin 3 using the UART format // without using the UART hardware void serial_send (char my_txt) ;IICalculate this constant float BitTime = 7YOUR VARIABLES HERE // Send Start bit over PB3 GPIO PORTB DATA R = GPIO PORTB DATA R & 0b1111 0111; wait us (BitTime)i 7YOUR CODE HERE Complete the function below for serial send (char my txt) to implement the UART protocol in software.
