As I was playing with PureData, I had to think back to my hardware controller/midi sequencer project. It is/was on hold, as other projects seemed to be more important. Also, I was kinda running into a wall trying to implement the readout of the rotary encoders. Probably it’s their quality, probably I’m simply too dumb [...]

So, I am currently researching ways of establishing a workflow for developing my hardware sequencer firmware. As someone who largely did web programming in rails during the last few years, I try to follow a few best practices, such as test-first, using automated tests and so on. Turns out that this is not too usual [...]
From the MIDIBOX description of the MIOS core:
The SRIO handler requires just only 75 uS to fetch the data from 128 digital input pins and to write out data to 128 digital output pins.
What this means is that he’s reading 128bits (from 16 74HC165 shift registers, all connected serially, IIRC) AND writing 128 Bits (into [...]
In my diploma thesis in 2002 I had to program a firmware for, let’s say a prepaid solar charger (sounds strange, but that was the idea). It was based on an MSP430 by TI, which is a very cool, ultra low power microcontroller. The problem was, that we had so many things to do with [...]
Hm, quite a cool idea: start all blog posts with a name of a former music-hardware-vendor :)
Anyway, while waiting for the LCD display which finally arrived on sunday (well, it arrived on saturday, but we didn’t pick up the notice that it’s been delivered to our neighbour, so I only fetched it on sunday, but [...]
