  1. Just finished building my TPD. It is recommended on the WIKI to test everything before soldering the led displays in place as they cover several of the 595 IC. The schematic is good but there is a lot more data that would make testing go much quicker and easier. Here are the work sheets I put together to test my TPD. Hope this saves you from having to work this out on your own.   The following Dout assignments are with the TPD directly connected to the core with nothing in between. This is recommended for testing as you do not have to worry with anything else if your core is good. Dout shift register chip chain order and pin counts   u1    u2     u6      u7      u8       u3      u4      u5        u9  0-7  8-15 16-23 24-31 32-39 40-47 48-55 56-63   64-71 SEG SEL  M2G  M2R  M2CA M1G  M1R  M1CA BiLEDS   U10 is on its own DIN serial chain. DIN is easy to test just close the switch and you should see the pin toggle in the console.   To test Digital Out Shift Registers from the mios console: Set dout 0 1 --> sets dout 0 to 5v set dout 0 0 --> sets dout 0 to 0v I liked turning things off as I went so only the one that I was testing was on.   IC IC pin dout#   led pin          IC IC pin dout#   led pin          IC IC pin dout#    led pin U3  1       40         10               U4  1        48         11               U5  1        56         12        2       41         7                       2        49          8                       2        57          9        3       42         4                       3        50          5                       3        58          6        4       43         1                       4        51          2                       4        59          3        5       44         22                     5        52          23                     5        60          24        6       45         19                     6        53          20                     6        61          21        7       46         16                     7        54          17                     7        62          18      15       47         13                     15       55          14                    15      63          15   IC IC pin dout#   led pin          IC IC pin dout#   led pin          IC IC pin dout#    led pin U6  1       16         10               U7  1        24         11               U8  1        32         12        2       17         7                       2        25          8                       2        33          9        3       18         4                       3        26          5                       3        34          6        4       19         1                       4        27          2                       4        35          3        5       20         22                     5        28          23                     5        36          24        6       21         19                     6        29          20                     6        37          21        7       22         16                     7        30          17                     7        38          18      15       23         13                     15       31          14                    15      39          15   Led matrix pin out from top of board: 13 14 15 16 17 18 19 20 21 22 23 24  0   0   0   0   0   0   0   0   0   0   0   0   1  0   0   0   0   0   0   0   0   0   0   0   0  1   2   3   4   5   6   7   8   9  10  11 12   For U1, U2, U9 and U10.  These IC are also not captive when the board is complete so you can get at them fairly easily. It would still be good to test everything with just the IC, caps, box header and resistors on the board. It is a lot easier to get at the ic legs with a soldering iron with the other components not in place.

I did this on paper and marked with red anything that was not working or just did not seem right.  I then went back and soldered anything that needed it again then retested. I am not sure why but some of those 595 pins just do not want to take solder. Maybe I just need more practice or flux.   on the encoder mine is turning backwards. I read elsewhere to set the config to the odd shift register instead of the even. I have not tried this yet but will give it a shot. Tested and I set the Encoder to 1 instead of 0 on the shift register and it is good to go now. Does anyone know how to get the display to run in the other modes? I see in the sequencer program that there are other modes but I do not see a way to alter it. Is there a pointer to the location of the text that displays on the TPD on startup? It plays "HW config v4l" on startup. I have not located it yet in the code but am looking.   I looked through the TPD wiki and the seq manual but do not see anything on the above.   Thanks for the great add on to the SEQ now I just need to get the panel cut for it.  
  2. MB6582: what's wrong with PICs?

    Hello all,   I almost completed my MB6582 and I am stuck at testing the main board. My idea is testing the PICs are running before inserting the precious SIDs.   I flashed all 4 chips with "setup_mb6582.hex", but nothing happen on the LCD...   I also flashed the 1kHz test FW --> nothing... :no:   Supply voltage is OK on all pins and MCLR (pin 1) is high as expected.   Cannot see any waveform at the oscillator's pins (10MHz XTAL and 33pF caps are OK). I would say the internal oscillator is not set for external xtal...   Anyone got a similar problem starting from blank PICs?   Thank you,   Walter
