Part Number: DK-TM4C129X
Tool/software: TI-RTOS
Hey guys im new to CCS and im using Ti-RTOS. I want to synchronize my code in multi threading as im calling two functions in main.In one im using ADC and in other i want to use Usb mouse host example of rtos but i cant understand how to use it here im posting my current code maybe u guys can help thanks.
