imxrt1052 flex io i2c dma

[ccc_clive]

flexio I2C 支持dma吗，我看其他的 spi uart I2S 都支持dma（sdk包里面有相关库文件），但是I2C dma的库文件就没有

Hello
I hope you are well.

FlexIO supports DMA, if FlexIO is configured as I2C however there are no specifical drivers for this. You need to refer to the already existing FlexIO uart/spi/… to implement one for i2c.
