yes, it was. but if i've read all 15 pages correctly there is noone known who ever got the sound for the b101rev4 running so i tried to make my own approach what until now was mainly looking for tutorials/explanations for similar modules and trying to apply them to my problem. The developer of the board has 0 explanations and doesn't seam to answer any questions/requests anymore.
Pass. I've only taken a quick look at the datasheet and noted that it doesn't quite match up. I don't have the schematics for the B101/2 so dont know how it has been wired. In theory there could be other circuitry in between, but I doubt it.
Support only Master Clock option
All 3 signals they refer to (SCK, WFS, and SD) show direction arrows going from transmitter (TC358743) to receiver (SoC). The TC358743 is the master of everything I2S.Since the transmitter and receiver have the same clock signal for data transmission, the transmitter as the master, has to generate the bit clock (SCK), and word-select (WS)
Sounds logical, but now I have an oscilloscope. I dont really know how to use it yet, but I got it to work somehow. The MLCK gives a clock at something between 11.18 kHZ and 12.42 kHZ which doesn't make any sense to me and the other 3 (SCK, WFS, and SD) don't have any output at all. If the b101 is the Master, why is there no signal?6by9 wrote: All 3 signals they refer to (SCK, WFS, and SD) show direction arrows going from transmitter (TC358743) to receiver (SoC).

ok, now it tells me the same in MHz. its propably supposed to be 12.288MHz. closer to what I expected, but still surprised that i don't have anything on the other 3mehrschwein wrote:The MLCK gives a clock at something between 11.18 kHZ and 12.42 kHZ
