I have wrote a qt program running with multithreading on uClinux. I run only one extra thread other than the main one. But the pushbutton really lags and sometimes stop responding. Please tell me if BF548 process suits for multithreaded programs? Or its just the coding problem? Note that I can run the same code on PC smoothly..
If you disable your slave thread, do you get better performance on your pushbutton?
