Problem of LCD connection with ESP32 pins, which are supported flash?
Posted: Mon Jan 08, 2018 4:27 am
At the first stage, I connected my LCD to ESP32 with GPIO25, GPU26, GPIO27, GPIO18, and GPIO23 as in the below figure. And it worked very well.
Unfortunately, this group of GPIO (25, 26, 27, 28, 23) are now busy with other connection. Then I tried to connect my LCD with group GPIO (11, 10 ,6 ,7) as in the below figure. But it did not work.
I know that these pin are support for communicate with internal/external flash, and are not recommended for other uses. However, I have a little confusion about this sentence. These pins are just only used for connecting with flash or they can be configured to use for other purposed.
Please help to check my problem.
