Re: 640x480 resolution

Ok, sounds good. Hmm, 2 bits per pixel gives you a bitter sweet degree of awesomeness; we actually designed the IC to have a 4 color mode where the hues are freely selectable, but due to an unfortunate mix-up, the signs of both U and V are fixed; only a few hues are possible. But it's one more degre...

Re: MP3Model forward/backward

Hi! It's been a while but I think you can just send a UIMSG_U32_PLAY_TIME_SECONDS message to it. Please see: http://www.vsdsp-forum.com/phpbb/viewtopic.php?t=1950&start=20#p12297 You're using the LCD display, right? Can you take a look at the VLSI Classic Player source code? I think it's the most co...

Re: 640x480 resolution

Hi! Just noticed this one... I can't understand how I failed to notice your post... Anyway, what's the status now, is it still unchanged? Are you still trying to make 640*480? With the PAL crystal, there's about 56 microseconds per line times 4.43 MHz times 8 PLLclock per colorclock, e.g. 56 * 8* 4....

Re: VSOS/VS1005 Educational Videos - Download here!

Hi! These videos are getting old. I should make new ones... The most important change, I think, is that since we got the command line shell working properly with the VS1005, the Developer Board is mainly used with the UART command shell, instead of the LCD display. The command shell works a little l...

Re: How to make config.txt

Hi!

You just create it with notepad, after mounting the flash to your PC using USB.

Please see the info videos:

Re: vs1053 Jack input

Hi!

The jack goes to VS1053 line in, right?

You could encode PCM (raw data mode) inside the VS1053, read the results and plot the results. That would give very accurate results.

Re: Can I change 1053 playback speed with a DDS as XTAL?

Thanks, and congratulations! It's always very satisfying to see something nice like this to get done successfully!

Pasi is here at the lab with me, he also seems quite happy, wondering if you managed to do the fine tuning successfully in the end... :)

Re: ESP32 game console/phone/media player with TFT and PAL/NTSC AV output via VS23S010/040

Hi! You have some great ideas! I'm not at the office, but here's a small reply with some ideas. You should get a VS1010 Developer Board to start with. It contains a VS23S010 with composite video output. There's a PAL video player demo for that board. Also I*ve done a blitter/tilescroller demo with i...

Re: Error when compiling Kernel

Hi! Supposing, that you have NOT modified the kernel yourself, the real simple solution is.... to compile it again and again until it is successful. The long term solution is to increase the size of the transient_i segment by a few words in the memory map file. Here's what is happening: The LCC comp...

Re: VS1005G-F-Q xreset remains at 0.5V

Hmm, seems strange... but these things have a tendency to always seem strange until the problem is found. Right now I'd keep looking at the XRESET pin. That's an input to the whole other bloc of clocking the chip etc. VS1005 power-up goes something like this (recalled from memory so may not be exact...
