embedded systems real time oprating system

Modify previous blinky LEDs code to have same result, i.e., blinking Red, Green, and Blue ones, respectively but this time instead of implementing three tasks: static void prvSetupHardware(void) { SystemCoreClockUpdate(); Board_Init(); /* Initial state for each LED is off */ Board_LED_Set(Red, false); Board_LED_Set(Green, false); Board_LED_Set(Blue, false); } static void vLEDTaskRed(void *pvParameters) { colour_t *colourCS; colourCS = (colour_t *) pvParameters; palette_t col = colourCS[Red].colour; portTickType numticks = colourCS[Red].delayTicks; portTickType xLastWakeTime; xLastWakeTime = xTaskGetTickCount(); while (1) { Board_LED_Set(col, true); vTaskDelayUntil(&xLastWakeTime, numticks); Board_LED_Set(col, false); vTaskDelayUntil(&xLastWakeTime, (numticks << 1)); } } static void vLEDTaskGreen(void *pvParameters) { colour_t *colourCS; colourCS = (colour_t *) pvParameters; palette_t col = colourCS[Green].colour; portTickType numticks = colourCS[Green].delayTicks; portTickType xLastWakeTime; xLastWakeTime = xTaskGetTickCount(); while (1) { vTaskDelayUntil(&xLastWakeTime, numticks); Board_LED_Set(col, true); vTaskDelayUntil(&xLastWakeTime, numticks); Board_LED_Set(col, false); vTaskDelayUntil(&xLastWakeTime, numticks); } } Have only one task implementation using Mutex concept!
