hi djamsia, sure. ping me an email.

dubtoms, if you don't mind getting your own panel made up, I've still got a couple of PCB pairs left.

There's also some bytes in the controller init sequence that determine the RAM to screen mapping. One changes the scan direction, the other the mapping so you can flip the screen without changing the drawing code. Similarly you can bake in the 2px offset. a cool - that would be one(or two) more byt...

Yes that could be it. I had a quick look into what could cause SIGILL on the Pi. Binaries built for ARMv7 or 8 would do this on an an ARMv6. File doesn't show the architecture the binary is built for, which is why they possibly all look the same, but "readelf -A " shows the cpu arch the binary was b...

As nobody else has mentioned it, a general observation on this from a linux/unix perspective ... Whatever it is you are running there is being killed due to an illegal instruction (SIGILL, signal 4). pd was reporting the same thing in the logs on the previous page. As it's the only issue you're gett...

mager, there's a Mouser cart for the red ATMega programmer that has all the components you need. A link to the cart is at the top of the ATMega programmer BOM sheet. Or if you've got a teensy3 spare it's easy enough to build one out of one of those. Details are in the programmer directory. Don't use...

I took everything from 0 and I followed the instructions on this page: https://github.com/westlicht/performer/blob/master/README.md and I find myself stuck again in the previous step: "xx:performer xx$ make setup_stm32 (mkdir -p /Users/xx/performer/./build/stm32/debug && cd /Users/xx/performer/./bu...

There's no reason i can immediately think of why those 2 programs wouldn't exhibit it & others would. They use both left & right adc & dac channels, as do other programs. I'd start by investigating the issue with output 2. My guess is that'll be the cause of the hum. There's a section in the build g...

Before you pass it on, that board looks like this one

Back on MacOS, that "another process has device opened for exclusive access" is probably why it's failing. Another process is running that has the st-link device open & it's preventing your st-flash command from accessing it. (It might be worth updating libusb if that didn't get done when you instal...

Macports (like homebrew) provides up2date ports of a lot of the open source projects that MacOS doesn't include by default. If you've got brew installed then easiest is probably just install stlink using the brew installer (i think "sudo brew install stlink" will do that. Sorry for being a bit vague...

So here is my last attempt: Go into the "performer" directory OK Launch the VM: vagrant up OK Open a shell: vagrant ssh OK Follow the procedure described by gbiz (p13) : git clone https://github.com/westlicht/performer cd performer git submodule update --init make setup_stm32 cd build/stm32/release...

I've just been trying to order some parts from RS & noticed no matter how much i added to the basket it added a £4.95 delivery charge, even though all items were marked as "free delivery" & the basket still had "place order before 8:30pm for free delivery". Turns out they're introducing a handling c...

No problem !
I'll add "--force" to the doc so anyone else trying this will use that.

efluon, i've seen that here too. try adding "--force" to the dfu-programmer erase command. ie

dfu-programmer atmega32u2 erase --force

Edit: these kits are now all sold Something i've been meaning to do for a while, this cv-19 lockdown has given me the opportunity to put together a small number of µDervish full kits for sale ... * DSP & control PCBs with all SMDs factory pre-assembled. The ATTiny & EEPROM are programmed. The boards...

I used TE Connectivity LR0204F series resistors, which are the correct physical size, they fit flush to the PCB & their legs fit the holes. I sourced mine from Farnell, but Mouser also stock them. The resistor bodies have to be 3.5 x 2mm to fit correctly. The body of a regular 0.125W resistor might ...

I forgot, theres also "SpinCAD+Dervish.txt" in that same directory on how to use SpinCAD with dervish. That's probably closest to what you want to do here.

If you get it working & don't mind creating a basic text doc on how you did it, that others could use, i'd happily add it to the FAQs there.

Dervish/uDervish will run any fv-1 binary, (same applies for any fv-1 based module). All you need to do is package them up into a Dervish format bank & upload them. There's a couple of FAQs that cover how to do this with the Dervish programming environment http://gbiswell.myzen.co.uk/dervish/DSP/doc...

One thing i just noticed i forgot to mention above, you'll need to create a udev rule file for the v3 in the vagrant image. In /etc/udev/rules.d/ you'll find 3 rules files with names beginning "49-stlinkv". You'll need to add a similar rule file for the v3 that contains the usb id for the v3. You'll...

Neil, if you don't mind sharing, can you remember where you got your 3478a calibrated ?. I really should get around to replacing the battery in mine before it runs down & it's cal cert expired a while back. Post battery swap would be a good time to get it done. Sure: https://www.absolutecal.co.uk/i...

For bench DMM, go for HP/Agilent/Keysight. I still reckon the best value-for-pocket-money is a calibrated HP 3478A. Look for a good one eBay and then get it calibrated (change the internal battery before you get it cal'ed). Last time I got mine calibrated cost me £69 which was less than half what I...

is there a specific tool you DIY'ers use for this though (to turn these things)? just a tiny screw driver? You need a "trimmer adjustment tool". eg https://uk.rs-online.com/web/p/trimmer-resistor-adjustment-tools/8524614/ One end is a regular screwdriver blade, the other end has a recessed blade, g...

I've just been looking for something similar for a LED lighting project i've been working on. I needed 12V @ 5A panel mounted, something that won't budge once it's in. I've ended up using RS sku 487832. They're not the cheapest, but certainly match your requirement if you need something at that curr...

... The Mutable VM won't see the STLINK-V3 at all even though it sees other USB devices. ... It sounds like you need to configure USB passthrough for the programmer USB id for the VM. Until that happens the host o/s will retain access to it. You can configure passthrough from the VirtualBox console...
