I'd be interested in Marin's opinion as he appears to have used both drivers extensively. I'd like a userspace program to actually try out Marin's driver, but I can still make some general comments: Things I like about Marin's driver: - It is only ~1/3rd the size. (by counting new lines) - The code is much neater. - It can acquire frames at 25 fps (real-time), according to Marin. - At least 1 person with intimate knowledge of the code seems keen to maintain it. Things I like about the sourceforge (SF) driver: - It works in CCIR mode (768x576) or 640x480 mode. - It is well tested. - It works with most kernel versions. ie. 2.2, 2.4, & 2.6. (mostly) - It works with multiple boards. - The code is moderately well commented. - It includes simple (user space) example programs. Clearly each driver has strengths over the other. It would probably be easier to upgrade Marin's driver to match the strengths of the SF driver than the other way around. The only difficulty might be in making Marin's driver work with older kernel versions. IMO, that's probably an acceptable sacrifice to make. (For users of legacy systems, we could point them to the (unmaintained) driver on SF.) > if you have 2 or more boards, could you check if > my driver is working with more than one board? Sorry, I only have 1 board available to test with. Marin, if you are considering upgrading your driver, I propose we send an email to the DT3155 SF mailing list & ask for help testing. (I already know of 1 other person who is happy to help test.) I recommend making userspace programs (like examples/acquire & examples/Xview in the SF driver) available first. Ideally, these example programs & user space libraries would become the major component of the evolved DT3155 SF project. What do you think?
