hi everyone,
I'm trying for a few days now to get the I2S Module of my ESP to a 53µs Bit-Timing, but it won't work.
I've had no problems to get it done by the SPI Output, but I need the DMA of the I2S and noch stuffbits.
for a bitlength of 53 µs I calculated a frequency of 17.241KHz (which worked for the SPI). The I2S outputs a much higher frequency which doesn't really seems connected to the set rate.
unfortunately, the I2S isn't really documented so far (at least with the arduino master IDE).
How do I get my 53 µs bits?
