This past week we have been working on improving some of the cross-development tooling that we use, which I will write about soon. But for now there is nothing really visible to show. So I will instead share with you the work I did today on getting the MEGA65 Audio Mixer
A quick post just to share the exciting progress with the injection-moulding tool manufacture for the MEGA65 case. The major pieces of the tool have now been produced, as you can see below!
First, here we see the inside of the lower case. The tools are all in negative profile. The big round
…I recently got the MEGA65's 8MB built-in expansion RAM mostly working. I say mostly working, because it was still doing various strange things sometimes. So I have been spending all my spare time trying to get this sorted.
While in theory the RAM controller is simple, in order for it to offer
…So, we have had HDMI-compatible video output working for some time. We even have the audio working on many monitors, but not all. There is something fishy with the audio output of the ADV7511 driver, when using certain TVs, monitors and HDMI capture devices. The symptom is either no audio, or no
…This short post is really one for the folks out there pulling their hair out with FPGA development in general, rather than the MEGA65 specifically.
I have had errors like the following a few times, and it always takes me a while to remember what the cause is:
ERROR: [Synth 8-2396] near character
I'm continuing to work on creating a tool to write updated bitstreams (or "cores", or whatever you like to call the things that turn an FPGA into an interesting computer 
Here's what it looks like after I got it working:
But let's go back to the beginning...
In a recent post, I confirmed
As many reading will know, the German arm of the project has been running a fund raiser since mid-October last year, with the goal of funding the manufacture of the injection-moulding tooling to build the cases for the MEGA65.
The main concerns that people raised about this, was that it was rather
