mipi dsi on arduino?

haimbilia over 6 years ago

what is the best way to connect an arduino to a mipi dsi screen like this one:

https://www.alibaba.com/product-detail/1-2-inch-390-390-qhd_60814031531.html?spm=a2700.7724838.2017115.1.3a2a624eRDLpMO&…

can you connect the driver ic directly to arduino and just write a library? or do you need bridge controller?

is the arduino even fast enough to handle such screens?

i found very little information on mipi dsi. anyone know a good place to start?

This display seems to be used in the STM32L4R9I-DISCO - EVAL BOARDSTM32L4R9I-DISCO - EVAL BOARD - there is quite a bit of info on the STMicroelectronics site.

I couldn't find and driver sources. The demo is just a binary AFAIK. Anyone found otherwise?

Hello. I know it is not an Arduino project but you could check this out: https://weekly-geekly.github.io/articles/444574/index.html He converts an SPI interface to MIPI DSI. He uses a flip flop to double the clock line and a resistor network to achive low speed and fast speed voltage levels. It requires higher clock rate so a simple 8MHz or 16MHz arduino won't/might not work. But a Bluepill (stm32 based arduino) or a Teensy should do the trick. I have just ordered a PCB to experiment with it, and to create a library.

Hope it helped.
