Issues with Audio_soc_example and LCD

Other Parts Discussed in Thread: OMAP-L138

Hello,

I´m currently working with the OMAP-L138 eXperimenter Kit and modified the Audio_soc_example given in the dvsdk to get Samples in the inputThread then making some audio processing with them and issue them to the output. Now i want to add some graphical Output on the ARM side of the Application which should get shown on the LCD/ Touch Screen of the Board, but every time i start the Audio_soc_example the LCD goes out and stays out, till i reboot the Board.

I´ve read that this failure may be caused by a competitive use of the i2c bus and a solution would be a initialization of the codec from ARM side. I am not very experienced, so perhaps there is some sample code on how to initialize the codec from ARM with i2c?

I would appreciate your help.


Thanks in advance

    Hi Korbinian,

    I see you are using OMAP-L138 Experimenter kit for Logic PD , that EVM comes up with the Logic PD BSL (Board support Library) along with the examples for all peripheral (Audio Codec too from ARM side ) it has both ARM and DSP side examples ,excellent package for beginners .

    You can register your EVM in the Logic PD website to download the source code
