I have a small 3.5 in TFT LCD display from a Chinese manufacturer. It doesn't have an integrated LCD controller. The documentation claims it is a "16 bit RGB/parallel interface" and it uses a Renesas R61581B0 driver chip.
These types of displays are very common and cheap. They sell for less than $15 a pop on Alibaba.com, but I don't really have a high esteem for these manufacturers since they do not provide any good / consistent documentation, and their English is riddled with mistakes! But I did get the display, and the product looks and feels like it will do the job!
My question now is, how do I get started ? I have looked on the internet and cannot find a good starting point. I have a 32MHz microcontroller in mind, but I am stumped on how to interface it with the LCD.
Most display projects online that I've seen assume that the LCD module comes with an integrated controller , so the MCU's job becomes pretty simple.. Provide image updates when necessary, and the controller will do the job of refreshing the LCD module at the required 60hz (or so)
This LCD module that I have has raw data lanes that I need to drive myself at 60hz. Are there any good documents on how to interface an MCU directly with such an LCD module?
I'll be happy with any info that points me in the right direction, whether it be an answer on stackexchange or a reference to any good documentation online.
