Plugging something into the jack might create a voltage divider?
Yep, here the voltage depends on the Impedance connected to the GATE OUT for sure! The Voltage applied to the 547 base is between something like 3,6V with Z=0 and approximatively 11V with Hi-Z, strange.
Led current depends on it too, between 1,5mA and 9mA.
This will work better:But it's 15V gate. A bit less because of the diode.

I was using the top right corner of this schematic from the YuSynth gate delay, except connecting the base of the transistor to the DOUT module.
Interesting, based on this diagram the LED should work without something connected, except if the load is a lot less than 10K, is your jack has a kind of bypass inside? Maybe the jack put the output to the ground internally when there's nothing plugged?

force a line return after 128 pixels
'Wordwrap' but not between the words ;)

Hi Chris,
It's maybe not exactly what you want, but you can try to rearrange the OLED in Column instead of Row, and work with the lines.
By using the help menu in the bootloader.set lcd_num_x (number of LCDs in X direction)
and
set lcd_num_y (number of LCDs in Y direction)
Not sure this will help you, but it can already force a line return after 128 pixels if you set lcd_num_x to 1.Best

Number 8 perhaps? :D
Though I think I have to get the beat LED installed to get the official stamp! How much clearance should I leave to fit your LED diffuser?
Thanks again everyone! If anyone has similar problems to the ones I faced I'll be happy to share my experience. :D
Let 3 mm, it will be fine! :)

Yeah!!! which number is it? 7 or 8 maybe?

try this hex:

This is a path issue. Did you follow this ? -> http://www.midibox.org/dokuwiki/windows_toolchain_svn#path_environment_variablesMIOS_PATH and MIOS_BIN_PATH need to be set ;)
Always restart you computer after this operation, for changes to become effective.

Ok understood you never use MIOS trunk.
You have to checkout the MIOS, using tortoise svn is very easy.
just follow this howto http://www.midibox.org/dokuwiki/doku.php?id=windows_toolchain_svn#tortoisesvn
this page is useful too: http://www.midibox.org/dokuwiki/doku.php?id=windows_toolchain_core#path_environment_variables
First try by yourself but If you're really stucked I can take the hand on your computer like we already did ;)
-
But question??? How did you tried the 8bit driver without the right recompiled version ???
Hummm lol -
I think you didn't refesh your MIOS folder since a long time ;)

You can also measure resistance between the USB B port (with power off) and PA11/PA12 on the socketed Waveshare MCU breakout, should be 22R.
This is not a Physical USB issue cause the bootloader seems to work otherwise the In/Out "MIDIbox SEQ V4+" port should not appear.
@synaptech
Disconnect all others USB, restart your PC.
Put a jumper on JPA0,
Connect your Core and launch MIOS Studio,
and tell us what happens, please...

I think I understood what TK did in the FM firmware.
You have to let the 8 bit connections and the USE_8BIT_LCD_DRIVER flag to, this will force the use of the custom driver"app_lcd_8bitdriver.inc" which is in /src/ folder, It's an 8 bit one but it doesn't matter your controller supports it.
https://www.dropbox.com/s/zpdxe6cfrxtmv04/app_lcd_8bitdriver.inc?dl=1
Replace that file by the one from my dropbox(I added the command in this file.)
movlw 0x08 ; Display Off rcall USER_LCD_Cmd movlw 0x0c ; Display On rcall USER_LCD_Cmd movlw 0x06 ; Entry Mode rcall USER_LCD_Cmd movlw 0x17 ; DCDC Power On (OLED-0010 controller only) rcall USER_LCD_Cmd movlw 0x01 ; Clear Display call USER_LCD_Cmd bcf MIOS_LCD_TIMEOUT1, 7, BANKED ; everything ok, make sure that LCD_TIMEOUT, bit 7 is cleared movlw 0x38 ; without these lines the LCD will not work rcall USER_LCD_Cmd ; correctly after a second USER_LCD_Init movlw 0x0c rcall USER_LCD_Cmd movlw 0x17 ; rcall USER_LCD_Cmd movlw 0x00 ; set cursor to zero pos rgoto USER_LCD_CursorSet
Compil it, upload a
nd tell me...

The pinout is good.
First did you check with standard 4 bit, without USE_8BIT_LCD_DRIVER option?
The controller is OLED-0010(WS0010) and seems to match HD44780 industrial standard BUT in the command table there's something which differs:
Page 22 of the controller datasheet
Maybe I'm wrong but this specific command is nowhere in the LCD initialisation:
USER_LCD_Init ;; notify that no graphical LCD is connected bcf MIOS_BOX_CFG0, MIOS_BOX_CFG0_USE_GLCD ; (Initialization of Ports: done in Init_Ports) SET_BSR USER_LCD_STATUS clrf USER_LCD_STATUS, BANKED movlw 100 ; 100 ms delay call MIOS_Delay bcf USER_LCD_LAT_RW, USER_LCD_PIN_RW ; LCD_WRITE bcf USER_LCD_LAT_RS, USER_LCD_PIN_RS ; USER_LCD_PIN_RS_0 ;; initialize LCD movlw 0x38 movwf USER_LCD_LAT_D rcall USER_LCD_Strobe_Set rcall USER_LCD_Strobe_Clr movlw 50 ; 50 ms delay call MIOS_Delay rcall USER_LCD_Strobe_Set rcall USER_LCD_Strobe_Clr movlw 50 ; 50 ms delay call MIOS_Delay rcall USER_LCD_Strobe_Set rcall USER_LCD_Strobe_Clr movlw 0x08 ; Display Off rcall USER_LCD_Cmd movlw 0x0c ; Display On rcall USER_LCD_Cmd movlw 0x06 ; Entry Mode rcall USER_LCD_Cmd movlw 0x01 ; Clear Display call USER_LCD_Cmd bcf MIOS_LCD_TIMEOUT1, 7, BANKED ; everything ok, make sure that LCD_TIMEOUT, bit 7 is cleared movlw 0x38 ; without these lines the LCD will not work rcall USER_LCD_Cmd ; correctly after a second USER_LCD_Init movlw 0x0c rcall USER_LCD_Cmd movlw 0x00 ; set cursor to zero pos rgoto USER_LCD_CursorSet
I think you have to add this command somewhere for "internal DCDC power On"
movlw 0x17 rcall USER_LCD_Cmd
But I don't remember where, in the app_lcd.inc maybe??? Someone knows???
Edit: I don't remember which lcd_init is active,- /src/app_lcd.inc
- /module/app_lcd/clcd/app_lcd.inc
-
/mios/mios_lcd.inc

Midi offer 16384 control with 16384 steps (14bit)... we call this NRPN
Right! I Forget it ;)

In that case I've got a solution for you but it's not ready for the moment.
In regular MIDI(UART) if the byte is >127 it is always recognised as a status byte, less it's always data. But the MCAN is not an asynchronous link, and each packet has is own header, like in an ethernet frame, then it's possible to transmit a status followed by some 8bit data, it's the position of the byte in the frame which determines what it is.
I will try to find some time to finish it, @Zam needs it for his project. @monokinetic also has a secret project around it.

Is it possible to send MIDI CC parameters where 2 CC channels are merged and allowing of sending 8bit values?
When you say "2 CC channels" you want to say 2 CC numbers?
MIDI can't transmit 8 bit value, max is 7bit except if you use two CC, one for MSB(Most significant bits) and another for the LSB(Less significant bits), which will give you 14bit resolution max.The Pitch Bend is already a 14bit parameter, but it's not CC it's PB MIDI status.
Best is to keep the resolution from your Pots(assuming they are 12bits ADC) to your DAC internally, and get less resolution(7bits) from external MIDI control.

Thanks for sharing! Has a bit of "Saturate" vibe going on
Yes did not check the levels and render on the NS10. This is just a quick jam... I've got a lot of work currently and just needed to empty my mind today.
1 hour ago, latigid on said:Did you slave the 909 or sequence from the v4+?
The 909 is in Sync, it's a 2 measures 909 sequence, I know it by heart, easier for me for the moment and it has its specific groove. But I learn slowly the V4, I will try with it next time, I promise ;)
The midi clock is coming from the Seq and is routed to the 909. There's 3 separated event layers on the Bandmaster, VOICE, REALTIME and SYSTEM Messages. Then the 909 just receives realtime.

Little jam on Sunday afternoon with my new SeqV4+
An amazing machine, the Echo Fx is so playable, all happiness!
Microwave + EX-800 + TR-909, everything thru my Bandmaster Router prototype ;)

If you're patient you can order an hot air station for a few.
When my weller felt, I ordered this one in the hurry thinking that it will be temporary. Finally I didn't ordered a new professional one cause this chinese Baku does the job.
For less than 60$.

I don't know about the RTPMidi itself, but connected to a MIDIbox Core in SPI MIDI only 8 ports(cables) are supported, means 8 In/ 8 Out.
Just by curiosity, how many MIDI gears you have in your setup?
