Schematics, circuit board designs, test/prototyping code for stuff I'm working on. Once these evolve to a full- blown project, they'll get promoted to their own repositories. But there may still be interesting and useful tidbits lurking within these files...
Contains three radio-frequency circuit board designs:
- bpf-0805-4pc-breakout: 2.4 GHz band-pass filter using Johanson or TDK SAW filter.
- saw-dcc6e-breakout: 315 or 433 MHz band-pass filter using EPCOS SAW filters.
- tc1-1-13-breakout: transformer-based balun using the Mini-Circuits TC1-1-13M.
Headers and low-/mid-level API for the [ST Microelectronics STM32F2xx microcontroller] (http://www.st.com/internet/mcu/subclass/1520.jsp).
Low-level API for [Wolfson WM8731 audio codec] (http://www.wolfsonmicro.com/products/codecs/WM8731/) I2C interface.
See the README in each subdirectory to understand what you're looking at. :-)
