Send data from ADC to CS43L22 DAC trough i2s.
Hi guys! In my project Im reading samples with the adc at 48Khz using timer interrupts and adcConvCallback, load them in a buffer of 256 samples and when the buffer is full I send it via i2s to the DAC . Im using two buffers, when the buffer A is full i send it and start saving samples in the buffer B, when its full I swap again so I have 256 samples available at any time.
My problem is that en every swap of buffers I heard a “plop” noise from the dac. Do you know how can I avoid that? It seems to sound at every time that a new buffer is sended via HAL_I2S_Transmit() . Im not using interrupts in the I2s, just call it at every time I have a full buffer.
