YASP update & name
I’ve decided on a name, at least for now, TinySynth. Basically because, well, it’s tiny. So a lot has, and hasn’t happened, it’s sort of being developed in fits and starts as and when I have the beans to work on it. Which I’m fine with. So let’s jump to it. First we got the display working, this was based on some code my partner had done for another project, so there are some psudo 7 segment digits counting from 0 to 999. Then we got the LEDs and switches working, these are on a pair of PCA9555 I2C GPIO expanders, so two wires gives me 32 GPIO lines, neat!…

YASP (Yet Another Synth Project) Part 2
Well the front Panel PCB arrived, it’s also the same size as the others, 45mm by 65mm but has 10 switches, MIDI in, autio out, USB-C PD power, 1.44″ TFT display, lots of LEDs and a joystick thing. Top to Bottom; I’ve included two 1/4″ audio jacks for scale (I ran out of Bananas). It’s not yet fully assembled, I’m waiting on the switches to arrive, but they’re due in the next couple of days. From there it will be software development time. It all powers just fine from the USBC connector, and will auto negotiate the best power from any USB-C PD capable supply, though I’ve limited it to…

YASP (Yet Another Synth Project)
ok, ok, I know, I should finish something first…… but…. no seriously, let me explain…. So one of the things that frustrates me is having to sit in my study of an evening to play with my synths, it takes me away from my other half and my Suzi dog. Now my other half usually plays games on her laptop, or sometimes does some coding, so I figured why not make something I can have sat on the sofa next to me instead of needing my lab, power supplies, big screens, etc. So I remembered I had this rather nice little Alchitry FPGA dev board, I found that someone had…
