I have a Dash that was working back in February, 2016. I put the project aside for a few months, but am now trying to get back up to speed. Now, my Ubuntu laptop is not seeing the USB serial interface. I have other serial interfaces that show up as /dev/ttyUSB0, but the Dash is not showing up as I would expect. I may have a cable problem – it doesn’t help that all my other devices use mini-USB as opposed to the micro-USB on the Dash. So far, my pain is all self-inflected.
I have a FTD1232 board that shows up as /devttyUSB0 as it should. so I thought that it should be easy enough to hook up the Dash following your instructions here:
The instructions are for the Dash Pro and they reference U14 and U15. So, I go to the pinout diagram here:
There is no reference to “U” designations on the diagrams. I see Rx0, Rx1, and Rx3 and note that Rx1 and Tx1 are the only adjacent receive and transmit pins as implied by the U14 and U15 designations. If I stand on my head and start counting at zero, backwards from the “L” and “R” designations for the Dash (as opposed to the Dash Pro) I can convince myself that U14 is the Dash *RX1 signal on L04 and U15 is the Dash *TX1 signal on L03. Is that correct?
I don’t mean this to sound like a rant. I’m sure the problem is mine. Have I missed a table somewhere in your documentation?
Thank you for your help,
