Glasgow Interface Explorer

Hi all,

I have been mostly in read-only mode lately, but I keep following 
interesting developments. Today I encountered something that I thought 
is worth sharing.

https://github.com/GlasgowEmbedded/glasgow is a piece of open hardware 
that features an FPGA and 16 digital I/O pins with a wide voltage and 
frequency range (1.8 to 5.5 volts, up to 100 MHz). The cross-platform 
software (GNU/Linux, Mac OS X, Microsoft Windows) includes a library of 
protocols, consisting of Python that runs on the host system and some 
HDL that is synthesized and uploaded to the device. They employ an open 
FPGA compiler http://www.clifford.at/icestorm/ for that part. Apart from 
the usual I2C and SPI, they mentioned being able to interface with a 
floppy drive (I would guess, MFM encoding). The hardware claims to be 
expandable (you can supposedly chain multiple units together to get more 
than 16 I/O pins).

I am in no way affiliated with this project, and I do not expect to 
return any time soon to a hobby project where this would be useful, but 
I thought that people here would be interested. They are collecting 
crowdfunding at https://www.crowdsupply.com/1bitsquared/glasgow until 
February 2, 2021.

For a few past years, I have been meaning to buy something that would be 
supported by http://sigrok.org. A fully open stack (including open 
hardware) ought to have better potential in the long term.

Best regards,
