>miso-x-mosi you mean trying on spi.
no. just swap the two lines . (because i made this mistake, get zero data, because master IN connected to slave IN .)
and when set I2S in Cube, you can see, which pins are used, and the mode.
Well AScha.3 thanks for the response! Btw for a reason i cant change the send/receive pins from the .ioc
configurator for a reason! i used HAL_I2SEx_TransmitReceive and now i have real time data filling the buffer but i i also had to change hi2s2.Init.Mode from I2S_MODE_MASTER_RX to I2S_MODE_MASTER_TX.
A few things i ve noticed:
--When i use I2S_MODE_MASTER_RX, HAL_I2SEx_TransmitReceive returns 0 data
--When i use I2S_MODE_MASTER_TX and HAL_I2S_Receive returns 0 data and and i have no clock outputs from the mcu (master, word, bit clocks)
-- I have to use HAL_I2SEx_TransmitReceive in I2S_MODE_MASTER_RX that receives but also trasmits for the clocks to work and i found no way to only transmit
Is there a reason for all that or these trasmit/receive codecs you have to do both in order for them to work?
Thanks again for your time
Best regards
PP
