I've been using a beaglebone black (in debian) to communicate with my Matsuura MC800 VF (1993). It's got an old yasnac I-80 controller on it, and I have to drip feed most stuff because I've only got about 30k of program memory. For the record I was unable to get this to work with USB to serial adapters, in both Windows and Linux. As soon as I went directly to the UART pins it was easy.
I recommend using stty to set the serial port, and the just copy the file you want to the serial port. For example, I run at 4800 baud, 7 data bits even parity 1 stop bit with software "flow control". Here's how I set the port settings for the beaglebone black: stty -F /dev/ttyS1 4800 parenb cs7 -icrnl ixon nl1 cr1 then do something like this to copy the file to the serial port and have the beaglebone spit it out. In my case I'm using serial (uart) 1: cp /pathtofile/mycncfile.nc /dev/ttyS1 You can do it in Python, but I'd get it working at the most basic level first. With Python there could be additional software buffers between you and the cnc machine that could cause issues. I use a max232 between the beaglebone and the machine for level shifting. I'm currently using an old one a buddy soldered up and had laying around, but I'm going to put in a more professional max232 in the next couple days. The one I got was on Amazon link here: https://www.amazon.com/gp/product/B00HKIMBZW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 It looks, good, but I haven't tested it yet. Now, I've got a question for you guys. Has anyone been able to get hardware flow control working on the beaglebone black in debian? -Marc On Wednesday, November 15, 2017 at 1:49:26 AM UTC-8, Jeff Andich wrote: > > Yeah we also stumbled last-week on Tx and Rx being swapped/ ‘crossed’ for > UART1 (?only?) on the BB-X15 AND TI 572x evm REVA3 schematics.
