Hi
Did anybody try to Interface graphics LCD with stm microcontroller. I am trying to do same but I am facing some problem with voltage level. I think graphics LCD accept 5 volt and stm can provide 3.3 voltage only.
That's a useless question without referring to a specific graphic LCD controller. Many recent GLCD controllers are e.g. 3.3 V only and must never be connected to 5V.
Why fo you think it's code?
For sure the logic levels can differ from one microcontroller family to another.
Like so often: The answer can be found in the datasheets. Therefore FvM asked for the exact type.
Input levels and output levels..
High, low, max allowed.
