I'm about halfway through modifying the cape PC board. Correct me if I'm wrong but because the BBB has internal flash it's expected that the OS and all run on that. That then frees up the pins on P8 marked MMC1_-- ? I'm basing this off the charts from www.ExploringBeagleBone.com. I have both editions of the Derek Molloy's book. I've added a CAN driver to the cape and I'm going to shift some pins down so the I2C pins can be brought to the header. What I'd like on the first connector is standard I/O and PWM out for spindle. Maybe even add the circuitry to create 0-10VDC. But there aren't enough pins on a standard parallel port to be able to do a spindle encoder or mpg. That's why I was looking at the RS232 and connecting to something like a MODIO or for that matter something similar that runs on CAN bus with CANopen protocol. If you can afford it there are some pretty nice robust displays with CANopen or J1939 used for industry. More as I work out what I'm trying to accomplish.

As long as the daughter boards match the cape no probs. In my defense I was looking after a Beagle pup we got at 8 weeks old. There's also the raw pins brought out for the ADC, an I2C bus and for an external power switch. I don't know if you've seen my spread sheet but I've thrown it up (hopefully without any major typos). With a bit more thought some pins would have been better elsewhere, but I was aiming at a simple conversion from a 2 port PP setup. Hence the "output daughter board" resembling a Std PP and the Input resembling a PP setup for input. I figured that the main cape could be used on it's own for experimenting with external devices without the daughter board. But I'd be interested to see your progression, as I have time on my hands now as I stopped the Linuxcnc Mint ISO's, the devs prefer seem just to support Debian. So you want someone to bounce ideas off my old noggin is pretty hard & dense.
