EJK Posted April 17, 2013 Report Share Posted April 17, 2013 Hi! My research group currently uses an NI cRIO as an FPGA and processor, with a custom breakout board for low-level robot IO: http://cwrucutter.wordpress.com/2012/11/09/cwru-cutter-robot-architecture-low-level/ I would like to use a Papilio instead as a customizable, low-cost, all-in-one SOC which interfaces with a higher-level PC. So, I'm putting together a MegaWing for robot I/O based around the Papilio. I'm curious what (if anything) people would like to see on a robotics-oriented MegaWing. Here's my current list of requirements based on my robot:4x Serial ports. Not sure if we need RS-232 or TTL. Possibly both.4x Differential line receives4x Relay Drivers. Capable of sourcing enough current for a relay (100-300 mA)8x Analog inputs. Or so.8x Straight-through GPIOs with pull-up resistors. Used for various switches, indicators, or digital IO (PWM input/output, other SPI or I2C peripherals, etc)2x H-Bridge motor controllerAre there any other things you'd like to see for robotics (maybe an onboard IMU IC, or something of the sort)? Or things that maybe arent so necessary? Also- 2 spare wing slots (as in the Retrocade) would be really great for a robotics application because we could add smaller wings if it turns out we need more IOs based on the specific application. Thanks for any input! EJ Link to comment Share on other sites More sharing options...
