Ramchander 0 Posted January 8, 2018 Share Posted January 8, 2018 I am trying to read a .wav file from sd card and play it using I2S on CC3200 audio booster in Energia. I have modified the Wifi audio example of CC3200 sdk for this. The dma is setup in ping pong mode and sd card loads data into the buffer but the tx dma interrupt fires only once in primary mode and once in alternate mode. I could not understand why its firing only once. I have configured I2S in stereo mode with 16KHz sampling frequency and 16 bit size. This is my tx dma handler .

energia 485 Posted January 8, 2018 Share Posted January 8, 2018 This seems pure CC3200 SDK code and not related to Energia. I would encourage you to post SDK related questions on e2e here as it is monitored by the CC3200 experts. https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968 Quote Link to post Share on other sites
