Interface TFT display with STM32
We are using the parallel connection for the tft, there are 8 DATA Pins and 5 CONTROL Pins. It would be really easy, if you connect all data pins together.
LCD 20X4 using I2C with STM32
To initialize the 20×4 LCD we need to send some sequence of commands to the display.
Cascading Dot Matrix and STM32
In order to connect the displays in cascading mode, the data output pin (Dout) of one is connected to data input pin (Din) of the other display. All the displays are connected to the same CS pin.
