Since there is a mysterious lack of I2S on the new MCX A series.
I wonder if we could make use of the SPI peripheral to achieve it being an I2S master, i.e. making use of either a timer/trigger or some way of connecting two chained DMA's to toggle a gpio to run the LRCLK/word-sync.
would be super with some guidance on best approach (not knowing the a series features well enough.. yet!)
ran across this article that is covering same idea
what would be the smartest way on the A
Hi @dav1
In theory, SPI can simulate i2S. But currently, the company does not have an AN on the new MCX A series.
Although SPI can simulate the I2S protocol, this approach may not perform as well as dedicated I2S interfaces, especially in high-speed data transmission and high-precision audio applications.
Hope this will help you.
