Connect SN65DSI83 LCD to STM32F469

[Dallton96]

Hi, i'm developing a board with 7" lcd (LVDS) so i'm really hesitating about if is right to use a SN65DSI83 for this, my STM32F469IIT6 only have 2 DSI Lanes. I'm connecting the i2c lane from SN65DSI83 to i2c of STM, i just copied the circuit of cm4-baseboard-lvds-adapter (https://github.com/antmicro/cm4-baseboard-lvds-adapter) and adapted to mind. So i'm really new in this kind of applications and i don't know if i should first read the registers of SN65DSI83 and then change (i want to implement a logic that if the registers are correctly configured just read and pass but if these are not right, my stm32 write the registers) or if every time that i have turn on my circuit, the STM32 should configure all registers. So some one have a tutorial for write on the screen with the comand mode? I just make some changes but i think in the future will put only springs for my aplication. So if someone can help me with this o maybe there are some documentation that i had no reading.

Hello @Dallton96

Firstly, I apologize for my late reply.

I recommend you to look to some LCD_DSI examples in STM32CubeF4 firmware.

Also, I think Introduction to DSI host on STM32 MCUs and MPUs application note can help you. This application note describes the DSI host interface on STM32 MCUs and MPUs and focuses on presenting different operating modes of the DSI host. It also provides practical examples on how to configure the DSI host depending on the operating mode

I hope this help you.

Thank you.
