RT1011 QSPI implementation

Daniel14 — Wed, 23 Nov 2022 04:39:13 GMT

HI，

I want to use RT1011 to drive AD7606 through two lines serial interface.

LPSPI is not suitable for its only 1-line SPI support. I have checked FlexSPI, all the demo code is for serial flash memory but not for QSPI ADC. I also checked FlexIO spi, the demo code is for 1 line SPI.

So, how can I drive AD7606 2-Lines SPI. thanks.

Regards

Tony

Hi @Daniel14 ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) How can I drive AD7606 2-Lines SPI?
-- First, the LPSPI supports dual-data transfers or receives, secondly, the FlexIO also can support it too.
