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..
I am doing building a GUI for pocketsphinx speech recognition API. When the button is pushed, it starts recording speech in PCM (signed 16 bits, 16 kHz, 32 frames and mono channel). I am running the recorder in the slave thread. So I can stop recording when I want to.
It takes about twice of the time after I release the pushbutton. If I release the recording button quickly, it stops after a few seconds. If I hold the button for about 5 seconds, it stops at the 10th seconds. Record over 10 seconds will crash the program..
