Reverse engineering SWD JTAG debugging/flashing protocol for Freescale chips

2017-04-17T09:08:18+00:00

One of the great breakthroughs of the Arduino has been that to get started, you only need the device itself and the software. The try/fail/try again cycle of development got reduced [...]

STM32F030F4P6 “AVR programmer” board

2017-04-17T09:11:21+00:00

by Krzysztof Foltman After the initial success with LPC810, I was ready to work on something with more memory and more I/O. Searching the Farnell catalogue for simple, low-cost and [...]

LPC810 board

2017-04-17T09:15:04+00:00

by Krzysztof Foltman This is my first successful attempt to do something with a 32-bit microprocessor in a circuit of my own making, instead of relying on commercially-available development boards. After some [...]

The yellow panel – prototyping utilities.

2014-09-05T09:47:00+00:00

The recent DirtyPCBs.com paneling experiment resulted in a nice new addition to our prototyping toolbox: the yellow panel. The yellow panel contains: Wolfsom SMT microphone breakout with small amplifier QFN24-to-dip [...]

Dealing with PCB artwork: procedural vector art tooling for Eagle

2014-07-25T14:09:51+00:00

I like decorating PCBs. After I've spent ages designing and routing a schematic, I want it to look nice. Sadly - this is very badly supported by most CAD software [...]
