Thanks for the reply, power was fine, 2 amps if needed, just sorted it out, I'm using the displays from Rapid Electronics, they have worked fine but when the Aout ng is connected it won't function, it is the RD 5 pin of the PIC, it won't drive both the display and Aout ng board, I've disconnected the display and have the Aout ng connected directly to RD5 and run the line to the displays through a 1K resistor and the display and analog out are both now working. Maybe the Rapid display's input's are pulling the line down too much, I'm no expert but the 1K works for me. Thanks again for taking time to reply, hope this helps someone else.

Hi, tried to connect my Aout ng from my Midibox CV to my 1 year old fully working SEQ3 and found the Aout ng will only work when the core display is unplugged. Looking on the circuit they share the RD5 from the PIC. If I connect it to the display it stops the Aout ng from functioning but disconnected from the display and the Aout ng works? Is there anyone out there with any ideas as to how I get around this problem?

Hi, has anyone got the Aout ng board working with Seq V3. The gates are working from the core but I,m not getting anything from the Aout ng. The Aout ng works running Midibox CV so I know the board works so I'm stuck.

you would laugh at the constuction, all on bits of boards my seq 3 is even worse, lots of ribbon cables hard wired and the switches are from an old IBM pc keyboard, works beautifully though, now I can integrate the d to a board on it now I know how to edit asms, thanks to you, I'll put some pics up, and thanks again, Graham

Wow thanks, that was it, I was just putting the asm file on its own. I didnt realise you needed the other folders make has generated a hex file from my wordpad edited asm I am so happy I've tried most of the weekend, thanks for your help and perseverance this is the hardest thing I've done building the midibox seq3 was easier I guess I'm more of a hardware person thanks once again. Graham

Thanks again for your reply. I've called my asm file test and saved it straight to C drive to make it easier. i then typed cd C: // now after the green writting it says /c $ so I think I'm at the C directory and i typed make setup but got the message make: *** No rule to make target "test. stop.

I have MSYS, when I run it it brings up a screen like CMD but with a flashing $, don't know what to do with it? thanks again for your reply, I've ltterally spent about 5 hours reading last night and 3 this morning going round in circles and feeling totally dejected as to how I cant do a simple task

I have downloaded docuwiki seems to be a collection of files, dont know what to do with any of them.

Have abandoned MPLAB and read the Quick Start Guide Toolchain Setup I can load the asm file in wordpad and edit and save it but which program do I need from those listed to create the Hex file from the ASM?

Been trying to use MPLAB followed some youtube videos to create a new project but when I try to build it I get the following Debug build of project `C:\Users\gra\Desktop\New folder\tes.mcp' started. Preprocessor symbol `__DEBUG' is defined.

I thought it would be simple to convert an asm file to hex but it appears to be out of my depth.

Ive found the wiki page but cant find anything on a build environment? thanks for your help

I've built the hardware and programmed the PICs and loaded hex files from mios studio all ok but stuck on editing and saveing an asm file to a hex to load into the core.

I looked at the link but it not sure what I'm looking for?

I'm using windows 10 and have built a midi cv converter all the menus work but the Aout ng board needs to the asm file to be changed, this is where 'im stuck. thanks for your reply

Hi, I've got my hardware working but I can't find anything on how to edit an asm file and save it as a hex. I've googled it and downloaded mplab and tried to follow the instuctions and got lost, can anyone point me in the right direction?

Hi, Got as far as burning the "software implemented loopback test" this worked, so I concluded that the hardware, pic and midi were all working! but still got the message that "mios wouldntt connect" tried to load a hex file and got the message "unable to connect" but it then loaded the file! I've now loaded hex files and got the core working and the display is working. no idea why mios studio says its not getting a response and can't connect but still it loads files? anyway I'm extremely happy now, thanks for all your help and giving me ideas and the will to carry on, I couldn't have done it without you so once again many thanks for your help and time responding to me.

Thanks, I will do, unfortunately my frequency meter wont measure that, thanks again for you help

I have managed to program a 18F452 with this programmer for the mr9090 drum machine.

my programmer dosen't have this, it has something similar I think, I included screen shots

Yes, the write and verify were fine, I don't know what you mean by the configuration bits? I just loaded the hex file into the programmer and pressed burn, is there something else I need to do?

Thanks, I get the message "no response from mios8 or mios3 core" however if I unplug the PIC and power the board, linking the midi rx and tx pins 25 & 26, and connect my midi monitor box to the core midi out, it shows note, mod wheel a controller information when I send it from mios studio, so I'm a bit puzzled. I've got another core board, so I'm going to build another with totally different components and a new PIC and I'm getting another midi interface, surely this will work, thanks for your help, it confirms I'm not doing something stupid. Thanks Graham

Hi, It's a MBHP board, the PIC is removed from the board and put in an adaptor in the PICKIT3 to program, then plugged in the mbhp core board, pin 1 is pulled up to 5v with a 100R resistor, is this correct?

Hi Bruno, Thanks for your reply, I got a blank PIC18F452 and downloaded the "miosv1-9h" and burned "bootloader_v1_2b_pic18f452.hex" from the "burner" folder inside the "PIC18F452 folder", is this correct so far? Graham

Is it possible to program a 18f452 just using a pickit 3 without resorting to midi. Ive spent 3 weeks trying to get mios studio and midi ox to communicate with the core with no success. I'm on my third midi interface, second lot of midi cables and built 2 different cores, one with a pic18f452 and the other with a pic18f4620 midi gets sent through the input and I've shorted the two pins together as in the instructions and midi comes out of the board and makes it correctly into my midi monitor so i can send midi notes, controllers and sysex from the laptop through the core and into my midi monitor but still cant get any core to connect to mios studio, just about to bin the whole lot and move on with my life tbh four wasted weeks!
