ESP_ERR_NOT_FOUND when esp_intr_allocby SvanteKaiser » Fri Apr 12, 2024 3:53 pm I get an error when trying to configure an interrupt for DMA. When I use i2s_read outside the interrupt everything works fine, so it's not a problem with microphones or I2S configuration....
I am using esp_intr_alloc(ETS_SPI2_INTR_SOURCE, ESP_INTR_FLAG_SHARED, spi_slave_isr_handler, &t, &SPI_intr) but I am getting error like ESP_ERR_NOT_FOUND. That's because the SPI slave driver internally does the interrupt handling for you. After the driver is initialized, the ...
