I am trying to configure a TFT LCD "EA TFT028-23AI" on evaluation board "ADSP-BF706_EZ_KIT_Mini". The LCD is included with a ST7789v controller and it has to be initialise in SPI mode with special commands before I can use RGB mode.
Anyone can explain to me the way I have to use to initialise the controller?
I suppose I have to install the driver for the controller and include the libraries in my project, how?
An example of the similar issue can be very helpful.
Anyone can please comment on following points:
- To initializing the ST7789 controller SPI, I need CS clock and MOSI. But I am not sure to use SPI1 or SPI2.
- It is maybe easier to use SPI1 regarding connection to the LCD, because there is a P5 interface for SPI1 on the BF706 kit board and I can just connect SCL and SDA from LCD to SCL and SDA on the board.
- If I want to use 4-Wire SPI interface, what does it mean?
I suppose the connection between LCD and BF706 kit board is:
SPI1_CLK --> SCL
SPI1_MISO ---> SDA
SPI1_MOSI ---> SDO
SPI1_SS ---> CS
Is it correct?
And I need an additional line to switch between data and command.
