I've now tested vga666 module hooked to AV3 RGBHV with the modelines below: ``` # 320x240 (jittery) #hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0...
Digitized audio doesn't go through FPGA, but the audio ADC chip includes a DSP which could be used to perform such mixing.
Cyclone IV PLLs impose some limitations as their lock range and multiplication factor is cumbersome to control dynamically. This is much improved in the upcoming Pro model. There has been...
Not yet. An official fw will be released soon which includes them.
There's on-going work for optimizing line3x timing (see #52), but 180+MHz is tall order for Cyclone IV. Decoupling sampling and output can only be done in a very limited fashion...
Can you elaborate a bit which resolutions you mean, 384x240 and 512x240 perhaps?
320x240 preset is already processed as square PAR. It'd be possible to add such option for 384x240 and 512x240 in certain output modes at least, but I'm not sure where...
Do you have "480p in sampler" set to "Auto" or "VESA 640x480@60"? Your comment implies that H.Samplerate has no effect at all which shouldn't be possible unless that option is...
I'm not sure if I understood correctly, but I presume the issue was "480p in sampler" having been set to DTV-480p which caused 640x480 Adv Timing adjustments end up with...
The video encoder should be fed with a subcarrier generated from a stable clock to avoid these issues. Such signal is available from dejitter/multi board but the standard instructions may...
