Title: Change polarity of Display Enable pin (DE)?
Post by: AT38 on July 23, 2020, 03:53:48 PM

BT815's Display Enable (DE) output is active positive.

I am trying to use a display with an ILI9806E driver which requires Display Enable to be active low.

How do I change the polarity of DE so that it is compatible with this display driver?

Thanks

Hello,

Unfortunately it is not possible to alter the polarity of the DE pin on the BT81x.
In such a case you would need to employ an Invertor IC.
