The solution in that case would be to raise the size of the I2S buffers. Thanks for the suggestion ESP_Sprite, I increased .dma_buf_count from 2 to 10 and the problem with skipping on playback is now resolved! That makes sense that another task also using SPIFFS was possibly causing a delay in the ...

Okay thank you! Ill try that out.

Okay, I may not understand how tasks are blocked/ unblocked fully. When I don't initialize the lower priority task, the wav player task runs without glitching. However when the other task is running, the wav task glitches. The lower priority task reads a text file and parses it. The wav task reads 1...

Hi there, I am trying to play a .wav file using the ESP32, I have successfully set up the I2S driver to send data to an external codec chip. My issue however is when I call I2S_write to write the next 1024 bytes of wav data, like this: It doesnt return in time to cleanly write the next 1024 byte sam...

Hello, Question about the I2S driver: I am trying to output a mono audio sample to the built in DAC. I have an array of samples (16 bit with only the upper 8 bits containing the sample). I am confused what the difference between the following channel formats are. Let's say I use I2S_CHANNEL_FMT_ONLY...

Hi there, I am using the display driver given in this example: https://esp32.com/viewtopic.php?f=17&t=3188#p14940 and github here: https://github.com/ESP32DE/I2S_parallel_example_drive_a_64x32_display It uses the parallel mode of the I2S driver with DMA to drive an LED display. My problem: transmitt...
