If you don't get it, then grab whole system image - it have about 4GiB 8kb/s I set core speed to 1 (causes lots of issues on the system but the display init's properly), effectively giving me a spi bus speed of 125k and you are correct, I was not able to retrieve anything useful yet can't even capture clock ticks or chip select for some reason (clock and L_CS always reads 0) but when reading MOSI ~100k times per second, I get random numbers, but so far every dump is a different starting to think that I am just picking up a random number from having MOSI floating.
It's kind of depressing really with some good opensource drivers, their products would see a pretty healthy boost in sales.įinally, IRT the FT232 the kedei "driver" sets the SPI clock to core/8. Chinese "manufactures" really don't care about GPL, and ignore it freely. the website on the server is in Chinese)Īs for GPL, good luck already traveled this road with the Sapido routers. While messing with KeDei's driver, I noticed some strange connections in the netstat on the RPi it's self going to servers that are in Chinese (well. I'll look how I can get in touch with manufacturer. Well, we probably can guess what manufacturer have approach to this matter (he probably don't give a about this.). They must supply you the source, or be in violation of the GNU General Public License. If the vendor got some specific patches (they do), you'll have to get the kernel source from them, patches included. At least one project is slowly going forward (there is still a whole pile of other pending projects.) I don't know how fast is "bitbang" mode in FT232 but I think this might not work, ftdi might not keep up to interface (usb normal devices (not HID) are polled every about 10ms.).Īnyway I'm not idle too, on weekend I committed a copy-paste (find&replace ) driver for DS2413 clone ( 3A 2100H ), I just can't find good time to push the code into github & issue pull request on rpi kernel repo (my git-extension is moody.) (on my YT channel there is demo movie ).Īlso I'm one step closer to the interface, I etched in last weekend too a one-sided pcb with fbtft-interface, so I just need to solder it, and hook up to lcd module. I don't know if retropie will work, ask on retropie forum - anyway I wouldn't be optimistic - issue is refresh rate, and it's going to your second question - no it is not possible to get decent refresh rate (decent > 15fps) with given hardware design of this lcd.
