hi all ,
we are working with imxrt1170 evk interface to a wifi module. here our wifi module using 3.3 voltage level for sdio .but i saw our source code is using 1.8 voltage level shifting. Should i switch the voltage 1.8v to 3.3v level on my code.
how can i do that?
when our code is voltage level 1.8v ,the cmd,data pins high state will be 1.8 v?
when our code is voltage level 3.3v ,the cmd,data pins high state will be 3.3 v?
Hi @Samsi ,
SDIO Voltage can be selected by SD1_VSELECT signal.
Please refer to EVK schematic.
