Assume the fоllоwing: [1] A cоrrect implementаtion of the relevаnt dmаc_init function, introduced in the previous question, has already been executed. [2] The EBI and USART systems are already appropriately configured for the contexts of this question. ———————————————————————————————————— Below is a partially written C function, void create_text_post(void), to read serial input from a connected computer and to create a text post containing at least one and at most 37 ASCII characters, not including an end character. In the context of this problem, if the Enter (or Return) key is pressed on a connected keyboard, an end character specified by the line feed ASCII character (LF, 0x0A) will be received. After such a key is pressed, the relevant complete text post, including the end character, must be transferred to external memory by way of the configured DMA system. void create_text_post(void){ #define LF 0x0A // Macro constant to represent the line feed character. uint8_t char_counter = 0; // Counter to determine input string length. static char text_post[38]; /* Array to temporarily store received text. * (NOTE: The `static` keyword is used so * that the array is only defined once, * no need to sweat.) */ char rx_data; /* Variable to store received character. */ while ( (rx_data != LF) || (char_counter == 0) ) { /* Wait for the input character to be received * from connected computer, and then load * received character into the `rx_data` variable. */ /* CODE SEGMENT #1, TO BE WRITTEN BY STUDENT */ /* Check if the the received character should * be added to the `text_post` array or not. */ if ((char_counter != 37) && (rx_data != LF)) { /* CODE SEGMENT #2, TO BE WRITTEN BY STUDENT */ } } /* Store null (zero) within `text_post`, * to denote the end of the text post string. */ /* CODE SEGMENT #3, TO BE WRITTEN BY STUDENT */ /* Configure any setting(s) of the DMA that pertain * to a particular text post. */ /* CODE SEGMENT #4, TO BE WRITTEN BY STUDENT */ /* Transfer the complete text post, including end * character, to the relevant external memory * location(s), by way of the DMA system. */ /* CODE SEGMENT #5, TO BE WRITTEN BY STUDENT */} Based on all comments provided above, complete the create_text_post function by writing code fragments for each section labeled "CODE SEGMENT #, TO BE WRITTEN BY STUDENT",

Yоu аre in а rооm full of people who believe thаt humans are not at all responsible for climate change and global warming. Now is your opportunity to change their minds! Explain why/how increasing greenhouse gases increases global temperatures. Explain to them what the word anthropogenic means, and give them at least two anthropogenic sources of greenhouse gases. Describe how scientists are able to study carbon dioxide levels from the past 400,000 years. Tell them what carbon dioxide levels have done since the industrial revolution and why. (6 points)
