So Marxon: Where can we buy such a marvelous thing?

Hi Everyone: Thanks TK for the suggestions.
press & hold the blue button on the STM32F4DISCOVERY board, and then shortly trigger the black button (to reset the device)Keep the blue button pressed! This enforces bootloader mode.
That happens OK when using the USB interface to MIOS Studio 2. However, with the MIDI interface, I get the following results:
Check query (blue button still pressed) - does this work?No. The left panel shows "No response from core"
Upload a firmware (blue button still pressed) - does this work?No. This message is returned: "WARNING: No response from core. Please reboot . . ."
Release the blue button after firmware upload so that the application will be started.The previous program is started.

Are you using the latest MIOS Studio release 2.4.6?
Yes. And I believe the boot loader is version V1.017 . Is that the latest one?
With this version the message should only appear if after the invocation of MIOS Studio the communication to a LPC17 core was successfully working, and thereafter you tried to connect to a STM32 core and the communication was failing.That sort of figures. Because the only way I was able to load the new application was to try to load one that was not compiled for the F4 (but was for the LPC17). It only loaded partway and then stopped. After aborting that load, I was able to load the new .hex file. In the course of trying different things, I got an interesting variety of error messages. I didn't write all of them down, but I will do that if it will help to understand the difficulty.

I’m trying to get my F4 core working. I recompiled Tutorial 001 (after changing the path variables to STM32F4 values), and eventually got it loaded into the F4 (I’m not sure now whether it was with the USB or MIDI connection) with MIOS Studio 2.4.6 on the Macintosh.
Next, I tried the same thing with Tutorial 002. Now I’m getting “File contains invalid ranges for MIOS32 LPC17!†And it won’t load with either USB or MIDI. I wonder where the reference to LPC17 is coming from.
The when I try to reload the .hex file for Tutorial 001, I get the same invalid ranges message. I’ve gone through the suggestions offered to smaudio, but they don’t seem to apply to my situation. What should I do next to troubleshoot this issue?

Hi Pete: I have heard the organ at Organ Stop. Charlie Balogh's drum tracks are wonderful. And Lew Williams is an exceptional musician. You are very lucky to have these guys on the musical staff. Are they using your MIDIbox sequencer now?

I suppose this is a poor time to ask this, but anyway: Are there any plans to produce a core module using the STM32F429? It has more memory, more i/o ports, and it comes with a LCD built-in.

if it weren't for Istel and Novski I would have never been able to program my LPC1769 on my Mac. Unfortunately, I didn't realize that I had to "activate" the LPCxpresso application before it would work with its free version. To activate it, you go to the "help" menu of LPCxpresso and select "Product Activation/Create Serial Number and Activate". That will give you a window with a long, long serial number that you shouldn't even try to write down because the are Os, 0s, Is, and 1s in it. Very confusing. I found the only way to get the serial number and activation code was to check the boxes to "Copy Serial Number to Clipboard" and "Open External Browser". When you do that, it transfers the serial number and states that it will send you an e-mail with the Activation Code. I waited for a long time to get the e-mail which never came. It turns out that the Activation Code is returned immediately just below the line in the external browser where the serial number was automatically entered. Then you can copy and paste that Activation Code into LPCxpresso Help menu "Enter Activation Code". From there things went smoothly :-)

Amazon is selling this book:
"Embedded Design with the PIC 18F452 Microcontroller"
Have you found it useful in your MIDIbox projects?
I think it's tacky to reply to my own message, but I thought I'd let the forum know that I just ordered this book from Amazon. It is kind of pricey @ $69, but it is a hardcover book. I'll let the group know whether I find it useful.

I am a new commer to the forum and am looking for help.
I am beginning conversion of a Moller pipe organ console to midi with the intent of using the organ keyboards and pedal board with Hauptwerk organ imulation software running on my pc.
I'm interested in this too. I've been working on a MIOS routine to keep track of the notes that are being played (and released) on several MIDI channels. This will let me turn off all notes that are ON on (e.g.) Channel 1 when a switch (on DIN) is turned off. I guess I'd be using tables to hold the note-on information. Have you been working on something like this?

How many DIN's and DOUT's are possible?

I'd be interested in the answer to this question also. From what I've read, a maximum of four DIN/DOUT modules are scanned. I'd like to modify something so that 8 or more modules could be scanned. What would be the consequences of doing this?
