Communication and/or networking between PC and Genesis?
Hi,
What are the methods available to do PC/Genesis communication? Say I want to be able to get debug message in real time from the genesis to the PC? Or send commands to the Genesis?
Thanks!
DJCC

The easiest method is probably through one of the controller ports. 4 pins for data with 2 pins for handshake will probably yield the best throughput. I've used such a cable connected to a parallel port in the past.
Using serial will probably use less CPU time (though at 4800 baud it's rather slow), but you'll need a level shifter to connect it to a PC serial port.
A Teensy USB is a decent option for connecting to a computer without a parallel or serial port.

He took down the old page on it. You can find it on wayback here:

He's still got the software for the link unit on his support page. You'd have to ask him directly if he has any more of these.

I'm not hardware inclined so any solution that's close enough to plug and play would be good for me. I'll email Krikzz about his link unit.KanedaFr wrote:yep, definitlyMask of Destiny wrote:

Got the WIP project on this one
Chilly, how much were the devices when you bought them?
https://www.sparkfun.com/products/718? is all you need
with the Serial part on the Genny and a terminal to communicate (like the powerfull realterm on windows)

If he's sold them all and people are still asking for them, there's clearly still a market for the items. Seems that's what you'd WANT to make more of, not the items still in stock that aren't selling.
Oh well, maybe we can make a open version of an adapter... use a PIC part and design a simple two layer board.

These Devices could be used well for logging Data from the Megadrive - a very good Idea - cheers!KanedaFr wrote:yep, definitlyMask of Destiny wrote:

I feel that something like the Teensy USB could be greatly extended as it has more potential with the AVR/ARM Microcontrollers - 'clever' logging, triggering - many, many Options
For the Case of uploading Binaries and Programs into the Megadrive's WRAM I am stumped as I am unsure what type of Software to use to upload from the Host's USB to the Megadrive's Serial-Port - is there something general purpose for this or would something have to be written to support uploading? Apologies for the USB Ignorance
I have exactly the same Type of Needs as DJCC.
I wonder if Krikz would mind posting the Schematic as it would be helpful at this Stage.
Cheers.

I personnally dislike the FTDI....always need drivers
I found 2 others USB to Serial IC which don't need driver and works on Linux
Don't remember the name (Cxxx and Pxxx ?)
For the speed, it's why I first plan to test with the serial available then use the MCD connector (thanks to research for the ECart)
I think any subhardware should use this connector not the EXT (or joy2)
Perhaps I'm wrong because i didn't confirm this with true test yet
