At the Vintage Computer Festival Midwest last weekend, I also got to test it on a serial terminal printer, which worked great!
My hovercraft is full of eels.
I had this same problem with two of my new Omega 2+s last week. After lots of searching around and digging into config files...I tried power-cycling my router and then they both worked. Might be worth ruling that out first.
As a followup to my Commodore 64 Omega2 Interface, I've designed a small and simple custom board that allows the Omega to be connected to any "retro" computer that has a DB25 RS232 port.
As you can see, it works beautifully on a WYSE terminal in VT100 mode!
The hardest part was waiting 6 weeks for the super-rare 2mm headers to arrive from China ;-)
Thanks, that does the trick.
No documentation that I know of,
How do you not have documentation for the code that ships on your own product? That fascinates/baffles me.
found the -c option by running ash --help
Fair enough, but the output is pretty cryptic:
root:~#ash --help BusyBox v1.26.2 () multi-call binary. Usage: ash [-/+OPTIONS] [-/+o OPT]... [-c 'SCRIPT' [ARG0 [ARGS]] / FILE [ARGS]] Unix shell interpreter
I don't see how you can glean much from that.
Figured out a good solution after a bit of digging. Shell script:
#!/bin/ash stty -F /dev/ttyS1 2400 while : do echo "" >/dev/ttyS1 echo "Onion Omega 2+ on Commodore 64!" >/dev/ttyS1 ash -l </dev/ttyS1 >/dev/ttyS1 2>&1 done
Right now I'm launching it manually, but could do it from inittab or some other approach at startup.
Still two outstanding questions:
I've done something similar with a Raspberry Pi, but I much prefer the Omega2's form factor, looks like it would fit tidily in a retro cartridge case, for example.
Some minor issues though:
There isn't quite enough oomph from the C64's User Port to power the Omega2 directly (through a voltage converter) - max at 5V is officially 100 mA but it can usually be pushed safely to 200 mA with a good power supply though. Still not enough for the O2+ unfortunately.
It's a little awkward to get a login prompt over ttyS1 as well as at 2400 baud, as per this post. A login prompt isn't strictly necessary, you could have a python script running for example to handle whatever, but a real prompt is pretty cool.
Way back in August last year I had an idea to "supercharge" my Commodore 64 with the Omega 2(+). This would require a second serial port, so the addition of ttyS1 on the Omega 2 worked out great for this.
Here's the breadboard circuit, using a 74HC245 for voltage level shifting (3.3V to 5V):
Awesome! How are you using the LEAP sensor? Do you have any videos?
I use the LEAP to detect hand position and turn it into motion commands. The robot follows your hand movements. I'll post a video "soon" ;-)
