Hi,
just wondering if the I2S DAC module still useful with the new core32 STM32F4?

the STM32F4 has a I2S onboard… http://ucapps.de/mbhp_core_stm32f4.html

yeah i know . i will quote the same than the other thread you answered me :

  • Pin mapping suboptimal in some cases. E.g., the outputs of the integrated DAC (not the on-board Audio-DAC) overlay SPI1 pins. However, one DAC channel has been freed up with the small drawback that SPI1 can’t be used in slave mode.
    The IO pins of the SDIO peripheral (high speed SD Card access) conflicts with the on-board Audio DAC, so that it can’t be used.
    Although the chip contains 6 UARTs, only 4 RX and TX pins could be found for MIDI IN/OUT. IN3/OUT3 even have to use two different UARTs.

That was the “Why” of my question.

 You maybe have some advice on the question ?
(sorry for undigging the thread)

By the way, some design thoughts about how to manage Analog Ins/Outs with new core32 would be some great add =)
