port for arduino #3

Closed ladyada closed 5 years ago

ladyada commented 8 years ago

hiya, i did a port for arduino - i had been using the $75 standalone programmers (they can store the BIN in a flash chip for untethered programming but requires win XP). using an arduino compat+SD card is way superior!

https://github.com/adafruit/Adafruit_RTD266X_I2CFlasher

works great, and am compiling some custom RTD firmware, with success so far. thanks for the i2c code :) life is :100:

Cool, now if we can master an open source firmware for the rtd2660, that would be great.

ahhh - im not sure i want to rewrite the RTD code - maybe better to just release diff's from the "RTD2660_AV1_AV2_081015" package? the base works, that way we just tweak it as needed?

ghent360 commented 8 years ago

It can probably be compiled in a way that the LCD timing table can be located in the binary and have a tool that patches the timings in the compiled code.

What RDT2660 board are u using?

handmade board, but its electrically similar to PCB800116 (HDMI -> TTL w/RTD2662) so far just got basic compiling + managed to invert Hsync and Vsync. pretty much just aiming to get 480x800 out (not 800x480). currently using https://github.com/avtehnik/RTD2662 as a base. binary patching of Panel2's data will probably be fairly easy once that is working!

eventually would like to pair with SSD2828 for DSI/MIPI - most small MIPI displays are portrait

ghent360 commented 8 years ago

Are you planning to rotate the input? I don't think the rtd2660 it is capable.

yah i dont think its possible to rotate but that's easy to do in the OS - at least Win & Linux can switch a monitor from portrait to landscape so you'd have to do that as well. not ideal but not a lot of other options!

ghent360 commented 8 years ago

I looked at a few MIPI displays and most of them can do hardware 90 deg rotation. Thanks for the SSD2828 tip. I was looking for a chip like that for quite some time.

ladyada commented 8 years ago

cool - i haven't seen that yet but maybe i'm not looking in the right place. is the rotation pin-strapped or is there a DSI command? i know there's video & cmd mode but have not done any actual work with MIPI yet

ghent360 commented 8 years ago

It's a DSi command.

Hi guys, Like you idea about connecting this RGB interface with a MIPI interface. I have already implemented some part of this. MY mipi interface is already working. But, RTD2660 some have is not giving me the right Pclk, even though I managaed to edit the EDID information in the eprom, which is used to program the RTD2660. I mean, the datasheet for RTD2660 has a whole lot of info on programming it, but its so breifly written and not elaborative to edit. Can somebody help me ?
