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 (to USARTD0 on the ATxmega128A1U) and to create a text post containing at least one and at most 37 ASCII characters, not including a final end character (null). In the context of this problem, if the Enter (or Return) key is pressed on a connected keyboard, a character specified by the line feed ASCII character (LF, 0x0A) will be received (but not stored). 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 (on * USARTD0) from connected computer, and then load * received character into the `rx_data` variable. */ /* CODE SEGMENT #1, TO BE WRITTEN BY YOU */ /* 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 YOU */ } } /* Store null (zero) within `text_post`, * to denote the end of the text post string. */ /* CODE SEGMENT #3, TO BE WRITTEN BY YOU */ /* Configure any setting(s) of the DMA that pertain * to a particular text post. */ /* CODE SEGMENT #4, TO BE WRITTEN BY YOU */ /* 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 YOU,*/} 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",
