I need to create code (state machine) that when the user types on or off the LED on the board turns on or off. This is for a texas instruments CC3220s board. Now it is time to modify uartecho. Your code will need to accomplish the following: • Use only one byte of RAM for the serial buffer ( char input; ). • Use only one byte of RAM for the state ( unsigned char state; ). • Receive only one character at a time from the UART and it is not buffered. • Turn on an LED when a user types ON into the console. • Turn off the LED when a user types OFF into the console. #include #include /* Driver Header files */ #include #include /* Driver configuration */ #include "ti_drivers_config.h" /* * ======== mainThread ======== */ void *mainThread(void *arg0) { char input; const char echoPrompt[] = "Echoing characters:\r\n"; UART_Handle uart; UART_Params uartParams; /* Call driver init functions */ GPIO_init(); UART_init(); /* Configure the LED pin */ GPIO_setConfig(CONFIG_GPIO_LED_0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW); /* Create a UART with data processing off. */ UART_Params_init(&uartParams); uartParams.writeDataMode = UART_DATA_BINARY; uartParams.readDataMode = UART_DATA_BINARY; uartParams.readReturnMode = UART_RETURN_FULL; uartParams.baudRate = 115200; uart = UART_open(CONFIG_UART_0, &uartParams); if (uart == NULL) { /* UART_open() failed */ while (1); } /* Turn on user LED to indicate successful initialization */ GPIO_write(CONFIG_GPIO_LED_0, CONFIG_GPIO_LED_ON); UART_write(uart, echoPrompt, sizeof(echoPrompt)); /* Loop forever echoing */ while (1) { UART_read(uart, &input, 1); //Insert State Machine Here UART_write(uart, &input, 1); } }.
