I made a post about this exact thing here a couple of months back, and received little help. One user was kind enough to get me started with some code that he had written for a Minix driver for that chip, but it only had the EDID driver code. So, I went on a manhunt to find anything I could. I knew that all of the information I was looking for had to be in a Linux kernel somewhere, so I started there. Here is the best code I have found to date:
https://github.com/rabeeh/linux-2.6.32.9/tree/c04795236fe2cb5024b0e6f278ec59346afd43b3/drivers/video/display/nxp This is the code for a full driver for the TDA19988 chip. Be warned, this chip is pretty complex compared to other components I have interfaced with. I have made some really good progress on my bare metal implementation and hope to have some code posted in a couple of weeks that anyone can start using. But again, this is a bare metal driver, not a Linux driver. Gerald, Would it be OK if I contacted you for the information you have? Maybe what you have will help me complete my driver a little faster so that I can share it with the community. There's obviously some interest in this. I would venture to say that if some easy-to-use code existed, the interest would be much higher :) On Wednesday, March 19, 2014 4:49:59 PM UTC-4, Gerald wrote: > > I have more. > > Gerald > > > > On Wed, Mar 19, 2014 at 3:49 PM, Robert Nelson > <[email protected]<javascript:> > > wrote: > >> On Wed, Mar 19, 2014 at 3:39 PM, <[email protected] <javascript:>> >> wrote: >> > Looking for the data sheet for the NXP TDA19988.
