I edited the MBSEQ_HW.V4 for the WILBA Panel for the STM32F4 where the SRs are set to 3, 4, 5 and 6, cause the wilba only uses 2 SRs for OUT, that part is working, Gates, Clocks and Triggers work with ~4.5 Volts.
The thing that is not working is the CV row from the AOUT_NG.
The MBSEQ_GC.V4 is on the SD card and I configured the AOUT via the Midibox. Type is set to 3 (AOUT_IF_TLV5630), which should be the right type for the AOUT_NG.
I now have some voltage, but not the 5V on C3 that I expected.
I triple-checked the whole connections and solderpoints of the AOUT_NG, all points of the DAC are at the right points, no bridges or something similar.
The receivers JAOUT is connected matching to the J1 of the AOUT_NG.
Jumper on transmitter is mounted like mentioned in the docs.
I don’t know where you are at in testing this problem but I had similar problems that are still unresolved. Check the forum . My clocks, gates, triggers all work just no CV and I know the Aout works because I built an NG to test it. Check the “testaoutpin” in MIOS, documented in the thread, that is particularly useful.
Did you select the right interface (AOUT_NG) with GP16 encoder?
If yes: there is a special testmode accessible via MIOS terminal.
Just open MIOS Studio and enter “testaoutpin”, this gives you some instructions.
Best Regards, Thorsten.
Yes I did, AOUT is selected and was written to the GC.HW4 config file
I will test the “testaoutpin” tomorrow and report then. (my Linux Mint does not support the right juice-stuff, so MIOS terminal will crash )
Receiver PCB JAOUT to AOUT_NG J direct 1:1 soldered … Pin1 and Pin measure correct 5V on J1
I also tested without Printercable and connected J19 of the STM32F4 board directly to J19 of the receiverboard … JAOUT of receiver_board and J1_AOUT_NG stay connected ( I didn’t want to desolder everything to test it with the special-cable you describe in the AOUT-Wiki)
Here’s my notes from my last attempt at getting CV to work, in MIOS Studio I found all related signals switched and my Aout_NG PCB was tested separately in a MBNG with a Standard Control Surface and the CV worked.
Aout Problem
Tested and found all signals good - core J19 through line transmitter & receiver to TLV5630 pins 2/3/4.
All switched as expected when using command “testaoutpin”
If all connections and power rails are good, then it’s possible the chip is defective. I think they’re quite easy to kill with ESD/excess heat from soldering.
I connected the AOUT via the Linedriver to see what happens
Results from the testaoutpin via mios terminal
J1 of AOUT_NG
between Pin 1 and Pin 2 I have 4.8 Volt
testaoutpin cs 0 => pin 3 => 0,13 V
testaoutpin cs 1 => pin 3 => 3,67 V
testaoutpin si 0 => pin 4 => 0,13 V
testaoutpin si 1 => pin 4 => 3,66 V
testaoutpin sc 0 => pin 5 => 0,13 V
testaoutpin sc 1 => pin 5 => 3,64 V
so all seems like it should be
BUT … PIN 13 (OUTB) of the TLV5630 gives 2,16V permanently … so … solderissue there … somewhere … or TLV damaged like latigid_on said …
so, luckily I have to place another mouser order next days … wheeeee …
I desoldered the TLV today, reconnected the board and did some measuring on the SMDpads to see if there are other errors.
All OUT’s except OUTB and OUTG have -13.78 Volts ???
OUTB and OUTG have 0.13Volts …
J1 Pin5 (SC) has connections to pads 1-2 and 3 of the SMD-field.
I know shit can happen and I know my soldering is not always perfect, but if there was no production-fault on my AOUT_NG board (which can alway happen) there is one now … So .. restarting at zero … buying a new AOUT_NG board and all new components … savest way
Just as another data point, I am still troubleshooting an AOUT_NG. However when I do the testaoutpin, i get 0v and 5 volts, which is what MIOS tells me I should get. That is except on one pin that is not flipping, so thats my next step, to trace that back, but that issue should be on the core board, not the AOUT_NG board.

Do you use a Linedriver or connect directly to the Core?
If you use a Linedriver, try connecting the J19 of the receiver to J19 of the board OR connect directly from the board J19 to J1 of the AOUT_NG (with the special cable)
