Re: Boosting STFM: 16MHz bus, 64MHz Shifter

Cool, :) Just a small note though.. the ST clocks don't actually have any skew at all. That was another AF argument I had with ijor :roll: He did agree with me in the end that there was no delays though, so at least that was something. IIRC one clock is inverted from the 8mhz, can't remember if it w...

Re: Boosting STFM: 16MHz bus, 64MHz Shifter

It might be worth trying the 64mhz into the GAL and bypassing the clocks generated by the shifter & MMU totally ? At least then you will have a clock gen which is as good as can be and things will be in sync (hopefully) better. IIRC the shifter and MMU clocks have a pretty slow rise and fall time, a...

Re: Boosting STFM: 16MHz bus, 64MHz Shifter

@exxos - do I remember correctly that you had issues with counterfeit GALs that weren't performing at the indicated speed? The 20V8-10 I'm using has a much whiter print than the 16V8-25 (both Lattice) and it would explain things if it isn't a true 10ns Yeah I've seen all sorts. Just do a A=B equati...

Re: syringe gun

I know it's only been a day but how's it feeling? Does it have the issue that "sealant guns" (silicone, caulk etc.) have that one the trigger is released there's still a bit of pressure on the plunger causing excess flow? It's gonna depend on the contents viscosity a bit, granted. Looks dead handy ...
