ga_realestate Posted August 4, 2016 Report Share Posted August 4, 2016 I am trying to use an external interrupt on the ZPUino to report status of an 8-bit counter via the USB port. I have the code working on a Arduino Mega. I want to port the code over to a Papilio One 250 and utilize the FPGA to handle some external output signals. Basically I am looking for the equivalent to the following Arduino code: attachInterrupt(0, capture_bearing, RISING); Any help would be greatly appreciated.

alvieboy Posted August 5, 2016 Report Share Posted August 5, 2016 Currently we do not suport per-pin interrupts. The main reason for this is because one would normally not use the GPIO pins for this purpose, but rather design a custom VHDL controller. What exactly are you trying to implement ?

ga_realestate Posted August 5, 2016 Author Report Share Posted August 5, 2016 Thank you for the response. I want to send the status of a state machine I have in the FPGA at a user definable rate via the ZPUino usb port to a computer. Basically I would like to plot bearings from a radio direction finder (heart of the state machine) to Google Earth. The FPGA drives multiple antennas and a display. The reason I am using the ZPUino is to have the ability to change baud rates, scan rates, etc via an Arduino sketch and windows app. Jim Quote Link to comment Share on other sites More sharing options...
