Tool/software:
Hi,
I’m testing the TAS2563 with an ESP32 using mono 16-bit I²S @ 48 kHz.
I²C communication works and all TDM_CFG0–10 registers are set, but no audio output is heard.
INT_LTCH0 consistently reads 0x10, which indicates VBAT below limiter inflection point.
Our supply is 4.2 V max (Li-ion).
Questions:
-
Can 4.2 V VBAT trigger the BOP/limiter event (bit 4 of INT_LTCH0)?
-
Where can I find register addresses/pages for:
-
LIMB_EN,LIMP_EN,LIMB_TH_MAX/MIN,LIMB_INF_PT,LIMB_SLOPE -
BOP_EN,BOP_TH, and volume/DVC registers (DVC_PCM,PB_CFG1)
-
-
How can I disable or relax these limits for playback tests at 4.2 V?
-
Are these values visible or adjustable in PPC3?
Attaching my register dump (although after PAGE 0, not really sure which address corresponds to which register).
Also attaching my I2S configuration for ESP32S3:
void init_i2s() {
// Channel config
i2s_chan_config_t chan_cfg = I2S_CHANNEL_DEFAULT_CONFIG(I2S_NUM_AUTO, I2S_ROLE_MASTER);
i2s_new_channel(&chan_cfg, &tx_handle, NULL);
// Standard mode: mono, 16-bit
i2s_std_config_t std_cfg = {
//I2S clock and slot configuration
.clk_cfg = I2S_STD_CLK_DEFAULT_CONFIG(SAMPLE_RATE),
.slot_cfg = I2S_STD_PHILIPS_SLOT_DEFAULT_CONFIG(
I2S_DATA_BIT_WIDTH_16BIT,
I2S_SLOT_MODE_MONO
),
.gpio_cfg = {
.mclk = I2S_GPIO_UNUSED,
.bclk = GPIO_NUM_11, // BCLK → TAS2563 BCLK
.ws = GPIO_NUM_10, // WS → TAS2563 WCLK
.dout = GPIO_NUM_20, // SDOUT → TAS2563 DIN
.din = I2S_GPIO_UNUSED,
.invert_flags = {
.mclk_inv = false,
.bclk_inv = false,
.ws_inv = false,
},
},
};
i2s_channel_init_std_mode(tx_handle, &std_cfg);
i2s_channel_enable(tx_handle);
}
Looking forward for your help!
