Hi,all

I want to know how to change GPIO voltage 3.3v to 1.8v when its signal is "1" on i.MX6DL soc

and I know ,on i.MX6SL, we have a bit LVE, I can change the LVE=enable, then when signal is "1" the GPIO output 1.8v.

can you give me help,3Q!

Hi tony

i.MX6SDL GPIO cell has not LVE configuration,

GPIO IO parameters are given in Table 23. GPIO DC Parameters IMX6SDLCEC

so for changing GPIO voltage 3.3v to 1.8v one will have to change power supply

for appropriate power domain, check Table 100. 21 x 21 mm Functional Contact Assignments.

Best regards

igor
