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 [...]
Tonight I reached another milestone on my way to world domination, in that I managed to 1) Assemble the USBasp AVR programmer I ordered and 2) build up a very simple setup for the ATMega644 (which is a possible target system for my hardware sequencer project) and 3) program the ATMega644 with avrdude via the [...]
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 [...]
