Audio board init with ESP32-WROVER_IB (16MB)
Posted: Fri Mar 20, 2020 11:38 am
Hello
In our project board we've using module ESP32-WROVER-IB with 16MB of Flash. To reproduce audio our board has the same esquema of the LyraT_v4.3 with some pins changes.
The issue is that the MP3 simple example works perfect buf when I tried to enable external SPI RAM (default conf), it doesn't work.
To add more information, configuration file is attached and the pin changes of our custom board are:
Here is the trace of the problem:
Thanks so much.
In our project board we've using module ESP32-WROVER-IB with 16MB of Flash. To reproduce audio our board has the same esquema of the LyraT_v4.3 with some pins changes.
The issue is that the MP3 simple example works perfect buf when I tried to enable external SPI RAM (default conf), it doesn't work.
To add more information, configuration file is attached and the pin changes of our custom board are:
Code: Select all
HEADPHONE_DETCET GPIO_NUM_16
PA_ENABLE_GPIO GPIO_NUM_17
i2c_config->sda_io_num = GPIO_NUM_32;
i2c_config->scl_io_num = GPIO_NUM_33;
i2s_config->bck_io_num = GPIO_NUM_5;
i2s_config->ws_io_num = GPIO_NUM_25;
i2s_config->data_out_num = GPIO_NUM_26;
i2s_config->data_in_num = GPIO_NUM_35;
And in i2s_mclk_gpio_select function gpio_num is forced to: gpio_num = GPIO_NUM_1;
Code: Select all
