Since it's now been more than five years since I left the project, I think I can finally reveal that the #RTL8762C is not only used in #SmartWatches, but also in #BLE connected #SexToys - the #SatisfyerConnect series to be precise.

Seeed Studio also sells a module containing the MCU along with the required passives and an antenna.

LCSC also has the bare MCU in stock.

I2C should give us access to the pulse sensor and accelerometer.
The LCD driver also should "just need rebasing".
I also want to make use of the DMAs. I'm still contemplating whether to abstract DMA as a MicroPython module or just use them in the background for UART and the LCD
My PR for #apolloFPGA just got merged 馃コ
It adds the #RP2040 rpi pico as a target platform for this open #FPGA debugger firmware.
Sorry for closing and reopening this PR. I was cleaning up my fork to be forked from this repo. This PR provides the files to run apollo on the Raspberry Pi Pico. Compile with make APOLLO_BOARD=ra...
Rendering from cli currently requires a very specific KiCad version in NixOS.
I just started a run that's building it on the fly, this could take a while 馃槄
It should get cached in cachix, bringing future runs down to ca. 1 minute.
I implemented automated export of production files, PDF exports and rendering of my KiCad template in github CI.
https://github.com/cyber-murmel/kicad-template/actions/workflows/build.yml
The newest version of #KiCad features 3D rendering from the CLI. I added this to the Makefile in my template repo.
Got sidetracked and designed an ADC that's just a chain of OpAmps and resistors that basically do successive approximation.
There is no feedback / only feed forward and the settling time is determined by the propagation delay of the Amps together with the passives. This results in some glitching at the zero crossing, to gating with registers might be needed.
It can be scaled to arbitrary bit depth and might be interesting for #ModularSynthesizers.
