performer (or is it per|former?) sequencer build

[dlavila]

I have a stencil, I can borrow it

[Quinie]

Hi Dlavila,

That is a very nice offer. But I'm hesitant to go with it. The stencil could get damage and Amsterdam is not in the neighbourhoud I could drive over.
My oven is still in build process so I would hold on to the stencil for quite some time probably.

I might get back to you, your offer is really appreciate.

For me the question really is do I need to get a v1.1 or will the v1.0 do? And if so are there any known bug I could possible fix myself on v1?
Else I could get my stencil and pcb made for v1. I don't mind the thonky or other jacks. Might be even better cause got a lot of them and most modules use thonky's these days.

The 1.0 is the official version from westlicht , the 1.1 was not from westlicht its modified for thonkiconn jacks and some other stuff but its no longer available. You are fine with the 1.0

Hello all,

I have a programmer question. I own a mac and don't want to figure out programming my performer in terminal so I borrowed my fathers old windows 7 computer. I installed the st-link software and the drivers as well that are on the st.com site. When I try and start st-link I get a message that I am missing "MFC140u.dll" and that the program can't start. Does anyone understand why I am getting this message and what the solution is? Also, My programmer is a: ST-LINK /V2 with the code "B 2014 45" on it.

EDIT: I fixed the issue and in case someone runs into the same problem the solution is to install both the x86 and x64 versions of Microsoft Visual C++ 2015 Redistributable Update 3 RC


Cheers,
Alex

Hi friends,

Gearing up to tackle this build.
I’ve never programmed an MCU before and am wondering if anyone has accomplished this by using STMs (newish?) multi-os solution on Mac OS? Everything I’ve read seems to confirm that I should be able to do this with a st-link/v2 and olimex adapter but wanted to see if anyone has had any success using this method or can advice of this wouldn’t work at all.

Thanks in advance!

Well, I spent more time trying to get the cube programmer to open on Mac OS than I did installing a fresh copy of Windows 10 via bootcamp and doing it that way... so if anyone is wondering about flashing with Mac OS.....

same experience here
another alternative is to use a virtual development environment with vagrant, the one from mutable instruments works to build and flash this project

Thanks for that! I’ll look into that if my bootcamp method fails but atm I don’t have any reason to believe it will. I’ll have to cough up the dough and pay microsoft for windows 10 eventually but i am impressed that they don’t cripple software.

I believe the demo version of windows will work well enough to run STUtility for programming this thing.

Yeah! It seems like it should get me through the procedure painlessly. I only mean to say that eventually I’ll pay my share for using Windows for free now — haha.

[sduck]

Once in a while it's generally a good idea to pay for the thing. In my case, many years ago I paid for a boxed version of the cheapest windows 7 - and the validation code (or whatever it's called) still works on the latest thing, which I've got running in boot camp on several macs.

Flash - yes;

build - make sure that you have installed the correct toolchain version otherwise you may run into random odd problems (stm32s can be quite sensitive to toolchain versions and you can see unexpected odd behaviour in different toolchains, which is why virtual machines are so nice as you can keep different build environments stable for multiple projects)

Hahaha yeah, long streaks with software always fees rewarding. I went about nearly a decade on a single license purchase for Pro Tools. Made it as far as PT12 before I eventually was needed to fork over cash because of OS comparability.

Ack. My performer has been working perfectly for like a year or more now. Today, powered it on and...

That particular array of pixels is static by the way, no movement. Is my screen dead? Or worse? Ack.

[steviet]

Ouch. Sorry to see that sduck! Here's to hoping for a simple speedy repair my friend!

[mcnys]

i'm going to order pcb and panel next week from jlcpcb, by looking in KiCad sequencers pcb is a 2 layer, right? Also panel pcb should not be thicker than 1.6mil?

Are any of the LEDs lit?

No. And the buttons are unresponsive. I have yet to remove the panel and check the components. Will spend more time with it this evening.

[cnicht]

Check the voltage rails are present.

The microcontroller needs both the 3.3V rails.

[sduck]

Ok, it's all very odd. U16 is working correctly, putting out 5v as it should. But for whatever reason by the time that 5v should be getting to U7 and U10, it's down to 1.7v, and those regulators are putting out -3.3v each. I can't figure out what's pulling it down like that. Maybe this is the excuse I've been looking for to build another improved version of this - my soldering is much better these days anyway.

[cnicht]

Are you measuring in the right place?

3.3 + 1.7 = 5.0

[sduck]

Probably not.

[cnicht]

I think you’re measuring the voltage drop across the regulators.

Is the microcontroller producing signals?

[sduck]

Sorry if I'm being lame about following up on this. I'm just not feeling an immediate need to get this fixed, but I probably still should.

Is there any kind of chart anywhere showing where to measure what voltages? I actually do know how to read schematics and measure voltages (at least I think I do), and am highly suspicious of what I'm seeing, but there's still a good chance I'm doing it wrong.

Edit: just checked the voltage again, after thinking a bit about how to do it. U7 and U10 are actually getting and putting out the correct voltages.

How do I tell if the microprocessor is producing signals?

[cnicht]

You’ll need an oscilloscope.

The microcontroller pins are difficult to probe but you could check where it connects to other ICs (U5 for example)
