Re: DIY Mutable Unsuccessful Builds

I use a brymen bm869s - ~€200 It depends how accurate you want it! If you want accurate v/oct tracking and want to reliably calibrate a dac to less than 1mv accuracy you need a precise voltmeter. No getting away from it.... But just use what you have - if your dmm is not very accurate or precise, y...

Re: DIY Mutable Unsuccessful Builds

Not sure I understand the question - it seems banal to just say “use an accurate and precise voltmeter” (Ideally you want at least a 50,000 count meter for precision - accuracy is another matter !). Not sure if that answers your question or not.... In his spreadsheet, he has values like this for a ...

Re: DIY Mutable Unsuccessful Builds

I have successfully built 2 stages modules, and everything works. But each step is totally out of tune with the others. I read a really useful how-to on a github that has a spreadsheet with voltages and how to edit the config to adjust them. But I don’t understand how to get such precise voltage mea...

Re: DIY Mutable Unsuccessful Builds

Greets - Why is the IC1 - Block 3.3V regulator not installed. The MCU needs this. Dude, I was just telling someone else I feel like I’m missing something totally simple and stupid. I even saw that IC1 on the schematic, but assumed since the BOM I had did not list a regulator for that slot, that it ...

Re: DIY Mutable Unsuccessful Builds

This post is regarding a Plaits board. First time posting, but I've searched through a lot of this thread and can't find a definitive answer about the vagrant STLink error "unable to connect to the target." I have never used the STM32F0Discovery until this project, and have no experience programming...
