Used this procedure with the three units: First I used Erase Device with AVRFuses for safety then, Copy and paste both grids_bootloader.hex and grids.hex files in the same directory Then open a Terminal window from this directory using right click Service>New Terminal at Folder. Type and enter the f...

Got one but it's acting weird. I got disappointed and haven't fired that case up recently, but it might be down to user stupidity but I doubt it, I had the original Grids when it first came out. Hy, how weird is it acting? Does it miss random gates/triggs that are still visible on the LEDs? I've re...

I don't know much about coding in Terminal, but I just opened a Terminal window from directory containing grids.hex file and ran the comand line you gave me. It loaded perfectly. I guess it did also write the lock value: lock:w:0x2F:m according to feedback message. But still do I get this bugg... :r...

I checked the soledring: no unwanted solder bridge. Tested the programming with the new fuses values and for sure some of the described bugs change totally: Now all modules seem to work the same, all channels generate triggers with Pots set before 12 o'clock and the Tap button works normally. But un...

uGrids and MI Grids DIY builds

Just finished the build and programming of three uGrids but encounter some issues. The programming was done quite easily with a Mac running High Sierra and an AVR Pocket Programmer on the hardware side. On the software side, i used this useful tutorial to generate the grids_bootloader.hex and grids....

I actually claimed victory too fast. One unit has a clock issue and the two other share a same strange behavior on Ch1 and Ch2: the rythmic patterns look OK on the LEDs but the trigs/gates OUTs don't always fire accordingly. The result sounds strangly regular making longer patterns but adds a bit of...

Soldering the crystals manually is easily done if you put solder on one pin first that you afterwards melt holding (or just having) the crystal in place. Not having any tiny solder bridge in between the pins of ICs and amps is the most common difficulty for those MI nano builds. To check everything ...

Soldering of the pots for this one required much more attention than for uBurst an uO_C DO you have a picture of the uBurst? Also, was it challenging to solder those crystals in place? I'm building a uBurst right now.. I had a few parts fuck ups in the kit I bought so I'm waiting for them to be cor...

Hello. Thanks for your answer. By continuity testing I mean testing shortcuts using a multimeter because I don't see shortcuts with the magnifying camera I use. The multimeter actually uses a small amount of current to check this. But I don't know if this can damage the STM32. About the color of the...

Thanks a lot for your advice. I didn't know about this Diptrace software. Just installed it. Very useful indeed! I'll need to check everything that is connected to the STM32 I guess. Regarding the U10 I used the part listed as Q1 in the BOM which is Mouser part number CSTCE8M00GH5C99-R0. A 8MHz crys...

Yo! The soldering is fixed. But still I have a similar error message while uploading the firmware. So the question remains: IC10 who's value is V2164SZ in the BOM and that links to the V2164M on smallbear electronics'web page, Are They The Same? Those guys don't provide any datasheet... seriously, i...

What do you mean by reloading frames? Executing the command: make -f clouds/makefile upload or: make -f clouds/makefile upload_combo_jtag ? That's what I did several times. I tried to do it also using the firmware update procedure described in the manual before uploading:"Set the MODULATION attenuve...

Is this a hardware or a software issue? Because there were a couple of uncertain things involved during the building process: First of all I did buy my PCB from pushermanproductions.com and it was hard to read at some places.
