Can't get my Core SysExed

Testing/Troubleshooting
1

Finally I have got my JDM working under XP and I have programmed several PIC. So I decided to try them in action, finished my core module, tested voltages, put in a  PIC programmed with BootLoader, soldered midi cable,  as in http://www.ucapps.de/mbhp/mbhp_midi_gameport.gif and hooked it up to my Live!. Configured MIDI-OX as in BootLoader page. Turned my core on got that nice string after that I tried to SysEx it but I only get that request string. Here is the log:

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT               
 0001D83D   9  XXX    F0  Buffer:     8 Bytes   System Exclusive

 SYSX: F0 00 00 7E 40 00 01 F7
 0066FF4B   9  --     FF    --    --   --  ---  System Reset

After first string I started sending mios_v1_3.syx, but as you can see it simply don’t get that SysEx. I tried to SysEx it witk onboard sound car, but get the same - nothing. What is wrong? I’m confused:-/, I checked all configurations, reprogrammed PIC without any use.

Hello Domas!!!

You should try leaving your buffers under sysex/configure to 2048 * 4 @ 700ms delay after F7. The delay should also be at zero. Thorsten had suggested these as a possible standard, and they work great.

Also go to the devices section and disable automatically attach inputs to outputs, go to the top right cell open the midi output and erase the input from the output.

I myself had problems initially similar to this.

I would check the midi ports and make shure they are connected properly first.

Second I would test my voltages, let me know what voltages you are getting ( Especially at the LCD +5v :slight_smile:

I would initially disconnect the LCD to make shure this is not causing problems like it did in mine.

You can test this

by removing the D7 and +5V line - in this case the LCD driver should

get a timeout and ignore all following calls to MIOS_LCD_*

Thanks Thorsten :slight_smile:

Check all your connections (all of them making shure buttons and AIN are pulled up/down properly.

If it seems to load the MIOS with the LCD disconnected check your LCD connections. If these are correct add a 100 ohm resistor at the LCD +5v. This helped stablize my system.

When you load MIOS you should see 13 checksums.

After loading MIOS it will restart and only send the verification string once. You can check and see if MIOS is working by send the string (F0 00 00 7E 40 00 0F F7) it should reply fairly fast. Also you can verify if MIOS is working by uploading the CRC application.

Let me know what you find!

Thanks, I will try it  :D
