  1. Where can I see the relations between the Arty Z7 board pins (I/O) and the FPGA pins? In "Arty Z7 Reference Manual" it is not enough information: only buttons, slide switches, LEDs and HDMI pins relations appear. (eg. BTN0 is D19) What about the rest of the pins (I/O)?
  2. Hello there! I am a newbie using ChipKit uC32, and wonder what is the meaning of underscored pins on J5 and J6. Pins 3, 5,6,9,10 May I use all J5 and J6 pins as I/O? Thanks in advance for any help.
  3. I'm trying to compile the Xilinx example file for the MIG generated DDR3 controller in Vivado 2015.4. I used the .ucf file to generate the controller just fine. But when I look at the .xdc file, I don't see the DDR3 pins. I see all the other interfaces I believe, except for the DDR3. Won't this prevent a design that uses the DDR3 from compiling?
  4. Hello: I am trying to better understand the functionality of the Chipkit Max32 board with respect to the analogWrite command. I have been testing pins A4, A5, 21, 23, 44 and 45 using the anlogWrite function. I am testing each pin separately, i.e. one at a time. I have the pin connected to ground through a 180Ohm resistor and monitoring the voltage across the resistor using an oscilloscope. I am using the following code changing the pin number in the analogWrite for each pin: void setup() { Serial.begin(9600); } void loop() { for (int i=0;i<256;i++){ analogWrite(4,i); delay(5000); Serial.print(i); Serial.println(""); } } I am using the delay(5000) command to give me enough time to monitor and measure the oscilloscope value and the Serial.print function to know where I am in the code execution. When I test the A4 and A5 pins, I measure 0V, regardless of the value written with the analogWrite. When I test the 21, 23, 44 and 45 pins the voltage is 0 until a value of 127 is reached. above 127 the voltage is 3.3V., constant. Do I need to initialize any other values for the analogWrite to function properly? Thank You
  5. I have an old Uno32 that I had not used and finally dug out. I am confused on the pin numbering. For instance I am looking for J6-7. Looking at the Uno32 reference manual, page 2 has a picture of the top of the board. balloon 14 indicates this is J6. the silkscreen on the board as 2 rows of numbers which looks like the lower right pin would be 0. and pin 7 is on the outer edge. then I need j6-11, however the silkscreen numbers go from 0 to 13, G, A. This does not seem to correlate with the manual. looking at page 11 of the reference manual there is a pinout table, but how do I find the Chipkit OR the connector pin #? Could someone enlighten me.
  6. Hi, I bought a Max32, and need to find out which one is pin 3 and which one is pin 5. Is there a spread sheet available for all the pin names please? Thanks, Jack
  7. A customer asked me this question: hi I'm facing a problem while using DIGILENT BASYS2 SPARTEN 3E board. How can a sonar unit(external hardware) giving digital output pulses can be connected to the pmods. How are the 4 pmods in the board connected. With thanks and regards Aparna
