    I looked around for some other similar National parts and found one that has a similar (if not the same) DSP engine: http://datasheet.elcodis.com/pdf/9/4/90447/lm49350rlnopb.pdf Check page 70 onwards or 87+ for the 5 filter bands. They are just 2 bits of cut off and 5 bits gain per band. Maybe...

    I was planning to do speaker enclosure compensation EQ in the fpga, but even better if the amp could do it. Maybe took a look at the EVM and its documentation? Maybe the companion PC software may have some notes. Class D is very efficient. Its headphone amp is alright, but not as good as a...

    Got it working. For now I am just putting in analog in thru the LINE_IN pins. As with all TI datasheets, their pdf is garbage and doesn't actually describe anything about LINE IN, I just got it working by guessing. Fan controller works great. It has both internal temp sensor + remote junction...

    It should be fine - UltraHDMI eats mode changes for lunch since it was specifially designed for such. I would guess there is some other problem which is probably related to the screen blanking. A pin with bad soldering/contact will still work most of the time except for certain data patterns...

    Ok, today I spent 10 hours debugging all my problems. 1. The first two boards have pulldowns on /INT1 because my documentation did not show the correct notation, so I thougth it was active high. Changed to pullup and all games started working, real carts, all 64drives etc. 64drive HW2 managed...

    For some reason it's booting but the bootloader hangs. This is the same phenomenon as the 3x3 board (it worked with 64drive HW2 but not real games or 64drive HW1). the VGA part is perfect though - it just works.

    No, it will not work well at all. Probalby has 1/4 its original charge capacity (they are Ni-Cd cells). You can open it up and order replacement cells, install them, and have it working just like brand new. I owned a Tek handheld oscilloscope for a while that had a totally ruined custom...

    To do low volume (1-10) costs around $85-100 each. I can only get the price down if I get more people together again.

    Flex is not included. I use the connector for testing and provisioning. I can't sell the flex because not only is it a big hassle for me to deal with shipping and payment for basically no profit ,I don't have enough flex. If you wanted, you could buy a cable off digikey to plug in and then run...
