Hello, I cannot get SoundSL working to detect the source of a sound direction correctly. To check how the library performs itself, I wrote a little test script.I assume a 1kHz sine wave to be sampled by a simulated microphone. At a sampling rate of 1...

Hello, I'm trying to get Acoustic_SL running to detect the sound location with two INMP441 MEMS microphones. Unluckily, Acoustic_SL does only return two angles {-87, 88} independent of the processed PCM values. May anyone have an idea of what might g...

Considering existing posts and instructions in the documentation, I can't manage the framework to call flushFrameBuffer() regularly after a vsync.The main issue is that TouchGFXHAL::flushFrameBuffer() is only called once after the first OSWrappers::s...

Oh, dear. Maybe I was thinking completely wrong. As the display has its own framebuffer: Is flushFrameBuffer() called when nothing has changed in the touchGFX framebuffer? I'll test it shortly.

The LED toggling works as expected. Also, a breakpoint in OSWrappers::signalVSync() is hit on each button press.

I'm aware of that. But all of the transmission (e.g. start of SPI DMA) would be located in TouchGFXHAL::flushFrameBuffer(), which is not executed (more precisely: it is only executed once after the very first vsync). That's why I have deleted all dis...

Does SoundSL deliver wrong results? (solved)

Why does AcousticSL always return the same angle independent of the data?
