Using code on TTGO T4 board

[fa1ke5]

On TTGO T4 GPIO26 used for DC signal of LCD. I make some changing in source code.
In i_sound.c i2s_set_dac_mode(I2S_DAC_CHANNEL_LEFT_EN); used GPIO26, i change it to
i2s_set_dac_mode(I2S_DAC_CHANNEL_RIGHT_EN);
but initialisation steel use both GPIO25 and GPIO26 for internal DAC, and im making some more changes
i2s_set_pin(I2S_NUM_0, NULL) //NULL is using both GPIOs
change to
i2s_set_pin(I2S_NUM_0, &pin_config);

and adding GPIO struct

static const i2s_pin_config_t pin_config = {
.data_out_num = 25
};

Now all work fine (but SPI work only on 26-30 mHz, for TTGO T4 need additional change in spi_lcd.c)
