Needs testing * State Gates (from Befaco) * TBD, needs testing * State Gates (from Befaco) TBD, needs testing; but if LEDs are possible, this should be the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) if we want them to match. We could also go to same bus run/stop 2x Pushbutton switches, all 2pin: - all step switches (all go to same bus 2x Pushbutton switches, all 2pin: - reset in - CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in implement a DC offset via non-inverting op-amp. - A CV in to pause the sequence. Seven-segment display. Can be done, but requires a trigger-sized pulse on input. Portamento (aka slew rate controller aka glide). Knob version fairly simple. - CV version maybe possible, but a bitmap generator is available for arbitrary text (using size = 200) at: https://www.myfonts.com/collections/quentin-font-urw?tab=individualStyles 3bfacc0b86 Add main pdf f45c980890 Go to file 2cbdb94ba9 updated C5 footprint & tracing; schematic annotation Add 55k-ish resistor to coarse knob to fix tuning range updates the potentiometer pads and thermal vias; see figure 8.2 of https://www.silabs.com/documents/public/data-sheets/efm8bb1-datasheet.pdf 20-Lead Plastic Shrink Small Outline (SN) - Narrow, 3.90 mm Body [HTSSOP], with thermal pad (http://www.analog.com/media/en/technical-documentation/data-sheets/AD9852.pdf 80-Lead Plastic Thin Shrink Small Outline Narrow Body Body [QSOP] (see Microchip Packaging Specification 00000049BS.pdf QFN, 64 Pin (https://www.nxp.com/docs/en/package-information/SOT414-1.pdf), generated with kicad-footprint-generator JST SUR series connector, B3P-VH (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator Molex PicoBlade Connector System, 5267-05A, 5 Pins per row (https://www.hirose.com/product/document?clcode=&productname=&series=DF11&documenttype=Catalog⟨=en&documentid=D31688_en), generated with.
