My first Core test

Testing/Troubleshooting
1

Hi everyone. I put together a core using Smash’s kit.  There is a sticker on the PIC18F4685 that says BSL V1.2B MIOS V.19F.  So I guess I don’t have to upload those as mentioned here http://www.ucapps.de/mios_bootstrap_newbies.html.

I thought I would give it a revision_id_v1a.zip test as mentioned here

http://www.ucapps.de/mios_download.html

I was expecting to get the Revision ID back as a CC.  I got a CC but I don’t know if this is right.  I have an LCD but it does not really show anything except it has a blinking cursor.  No text yet.  Could be a bad wiring job so that’s why I thought I would test first. 

Anyway, here are the upload logs and what I got back.

Starting upload of main.hex

Sending block 00003000-000030FF

Received Checksum: 38 - OK

Sending block 00003100-000031FF

Upload process complete

Now here is the Midi Monitor In log.  The first line is the “Hello World” from the PIC.  After that is what came when I uploaded the test.

I have no idea if this test succeeded or failed.  Once I figure that out, I will start trying to make sure the LCD works.  I was thinking I would see some text or something.

Thanks for any help!  I know this is pretty basic but honestly as a noob I am pretty happy I got this far. ;D

I guess I don’t have to upload those as mentioned here http://www.ucapps.de/mios_bootstrap_newbies.html.

Correct.

I got a CC but I don’t know if this is right.

Yep looks fine. A tip for next time: the logs you pasted are perhaps a little confusing… You’ve shown the log of the upload, and the subsequent CC messages after a reboot… Maybe separate the two next time for clarity… or maybe I’m the only one that didn’t realise that at first :wink: But at first, all those 7F’s made me go “that ain’t right!” hehe

I have an LCD but it does not really show anything except it has a blinking cursor.  No text yet.  Could be a bad wiring job so that’s why I thought I would test first. 

Did you wire it for 4-bit mode? That’s the default on a 4685… You can search for more info on that one :slight_smile:

Anyway, here are the upload logs

Looks sweet. Did you use smart mode and wait for upload request? Have you tried re-uploading the app?

Now here is the Midi Monitor In log.  The first line is the “Hello World” from the PIC.  After that is what came when I uploaded the test.

00000000029189 ms | Sysex message: F0 00 00 7E 40 00 01 F7  That’s the PIC sending an upload request

timestamp [unknown] | Sysex message: F0 … F7    Thats the 1st part of the upload

00000000864544 ms | Sysex message: F0 00 00 7E 40 00 0F 38 F7    That’s the core confirming that it was received correctly

timestamp [unknown] | Sysex message: F0 … F7    Thats the 2nd part of the upload

00000000864660 ms | Sysex message: F0 00 00 7E 40 00 0F 60 F7    That’s the core confirming that it was received correctly

timestamp [unknown] | Sysex message: F0 … F7    Thats the 3rd part of the upload

00000000864779 ms | Sysex message: F0 00 00 7E 40 00 0F 40 F7    That’s the core confirming that it was received correctly

timestamp [unknown] | Sysex message: F0 … F7    Thats the 4th part of the upload

00000000864933 ms | Sysex message: F0 00 00 7E 40 00 0F 60 F7    That’s the core confirming that it was received correctly

00000000867238 ms | Sysex message: F0 00 00 7E 40 00 01 F7  That’s the core upload requesting again. This shows us that it’s rebooted, which is what it does automatically after an app upload

00000000871353 ms | [b0 27 61] Channel 1: CC LSB 7 (Channel Volume) value: 97 [b0 27 61] is a CC (B) on channel 1 (0) sending CC# 27(hex) value 61(hex). This is how the app works, it shows the revision (whichis in hex) as a CC.

I have no idea if this test succeeded or failed.  Once I figure that out, I will start trying to make sure the LCD works.  I was thinking I would see some text or something.

You should also see the above number 27 61 on screen.

This brings me to my question: Why’d you run this app if you didn’t know what it did?

Thanks, Stryd, you’re the best!!!  ;D ;D ;D

As for your question, I probably didn’t express myself very clearly.  I read the page

http://www.ucapps.de/mios_download.html

and knew that this file would test the Core.  From the associated readme, I read:

Revision ID V1.0

===============================================================================

Copyright © 2006  Thorsten Klose (tk@midibox.org)

Licensed for personal non-commercial use only.

===============================================================================

This program displays the Revision ID of a PIC18F and sends it

also via MIDI as CC# event

Known numbers (mostly documented in the errata sheets of the PIC devices)

  - 0427: PIC18F452  C1 Silicon (latest and greatest)

  - 0C03: PIC18F4620 A3 Silicon (contains EUSART bug)

  - 0C04: PIC18F4620 A4 Silicon (contains EUSART bug)

  - 0C06: PIC18F4620 B4 Silicon (the good one w/o EUSART bug)

===============================================================================

I was expecting to perhaps see one of these numbers (actually, since my PIC number was not listed as a known number, I was not quite expecting to see one of those - however, since the last three revisions have sequential numbers I thought perhaps I would see 0C07 or 0C08).    I did not quite expect

00000000871353 ms | [b0 27 61] Channel 1: CC LSB 7 (Channel Volume) value: 97

Anyway, I will try that search on 4-bit like you said.  I really do appreciate that it does take your (and others) valuable time to answer noob questions and so I have and will continue to read as much as possible and take things as far as possible before even considering to post.

Thanks again!

Indeed, and it’s a positive result :slight_smile: We love when it works first time!
